Tutorial on Portable Rockwell Hardness Testing

Test Principle
During measurement with the Equostat 3 probe, a diamond indenter is forced into the test piece to be measured, and then released back out of the material. The indentation depth of the indentor is measured continuously during application and release of the test load. From the indentation depths d1 and d2 recorded at two defined loads, the difference is calculated: Δ = d2 – d1. This difference Δ is a measure of the hardness of the material.

Measurement on Basis of DIN 50157 (“DIN method”)
Both depth measurements d1 and d2 are taken at preload, first during application (d1) then after release of the total load (d2). The difference between d1 and d2 originates from the deformation response of the material to penetration.

Measurement on Basis of ASTM B724 (“ASTM method”)
According to ASTM B274 the depth measurement d1 is taken at preload, d2 at the total load. As this standard refers to aluminium testing, this mode is applicable only to testing aluminium alloys (i.e. if Material Group 6 is selected; for details please refer to 7.2 Material Groups)

Test piece preparations
Keep the test piece supported, flat, during the test, i.e. avoid movement. Ensure that the sur-face of the work piece is clean, smooth, even and dry. If required, use appropriate cleaning agents for cleaning, such as acetone or isopropanol (no water!).

Note:
The Equotip 3 indicating device can also be connected to Equotip impact de- vices which follow the Leeb principle. By combining Equotip and Equostat on the same indicating device, almost every hardness test application can be addressed.

• The hardness testing principle in Equostat 3 follows the Rockwell stationary test. As for the Rockwell test, no adjustment for the test direction is required. However, there are three main differences to traditional stationary Rockwell tests: 1. The test loads are lower. 2. The Equostat 3 indenter is sharper. 3. The dwell times during the test are shorter.

Installing the Measuring Clamp
The Equostat 3 measuring clamp is designed to facilitate the hardness testing of very thin or small samples. Optimum measuring performance of this clamp is guaranteed when applied to steel samples. Equostat 3 clamp measurements stand out due to extremely repeatable results.

1. Use the Equostat setup tool to release the cantilever. Turn it by 90°.
2. Take the probe and remove the foot. The diamond indenter remains mounted.
3. Screw the probe into the probe holder of the clamp clockwise (hand-tight).
4. Turn the cantilever so its tip is centered over the probe; tighten the cantilever screw securely using the 3mm Allen key setup tool.
5. The recommended clearance between the bottom of the probe holder and the sample surface should be between 2 and 5mm. Adjust the height with the two knurled screws.

Note: In case the probe connector is in an inconvenient position, release the set screw. Ensure that the springs in the mechanism do not get lost. Turn the mecha-nism into a convenient position, aligning the set screw with the guide channel. Lock the set screw so that the probe holder will still slide up and down without rubbing on the set screw.

General Considerations

• Due to the mechanics / physics of the ASTM B724 measuring mode, which specifies testing on aluminum samples, when using the hand clamp, slight but unavoidable elastic deformation of the clamp can noticeably affect the reading. It is therefore not advisable to use the Equostat 3 clamp, when using ASTM B724 measuring mode. Hardness con-versions according to ASTM E140, when using the measuring clamp in the standard DIN 50157 measuring mode are unaffected.
• When measuring cylindrical samples with adapters Z4 or Z4+28, make sure, the sample is not twisted on the clamp support (neither in plane with the clamp support, nor rotational round it). This is best ensured when the back part of the clamp rests on a table and only the sample support of the clamp sticks out over the table’s edge.
• When applying the load, slowly squeeze the leavers and allow the sample to adjust to the support. During the measurement, do not touch the sample, if possible. When releasing, grab the sample again.
• Whenever the sample geometry (i.e. the wall thickness) allowes it, freehand measurements usually offer better measuring performance. This applies particularly to measurements on cylinders.
• For small diameter rods (or stiff enough pipes), the V-notch clamp adapter Z2 has been designed. When installing the Z2 support ensure that the center of the V-notch is centered underneath the probe holder.

Installation of Standard Foot or Tripod
The round standard foot permits measurements on test objects that are only accessible from one side, such as large metal sheets. The tripod is used when the flat foot cannot be placed on the test piece without wiggling.

• The diamond indenter remains mounted (1).
• Install the foot on the probe (2).

Installing the Long Foot
The long foot increases accessibility of the Equostat 3 probe to constricted test piece geometries.

• Unscrew the reference mandrel (1).
• Demount the diamond indenter using a paper clip or similarly thin tool (2).
• Screw the extension rod onto the probe, and the in-denter onto the extension rod (3).
• Install the long reference mandrel.
• Install the long foot on the probe (4).

Installing the Special Foot
Two special feet extend the Equostat 3 application range to cylindrical test pieces.

• The diamond indenter remains mounted (1).
• Install the foot on the probe (2).
• Place the foot on the test piece and release the set screw on the foot. Then press down the probe onto the test piece and lock the set screw (3).

Testing procedure

Connecting Equostat 3 to the Equotip 3 Indicating Device

• Connect the Equostat 3 probe to the indicating device using the provided probe cable. • On the Equotip 3 indicating device press the on / off button for approx. 2 seconds to power up the device.
• Open the main menu by pressing
• Select “Bar graph” or “Basic mode” from the “View” menu (see section 6.1. “Views”).
• Select the suitable value for the surface curvature by pressing the F1 key. For zero surface curvature, select “Off”.
• Select the material group applicable to the test piece by pressing the F2 key (see section 7.2. “Material groups”).
• Select the hardness scale to be displayed by pressing F3 (see 7.3. “Hardness scales”).
• Select the number of readings n per measurement series by pressing the F4 key (see section 7.4. “Number of indentation tests per measurement series”).

Note: The material dependence for conversions of the Equostat 3 hardness is small. If the elasto-plastic properties of your test piece material are very different from the selectable materials, i.e. large deviations from stationary test results are found, please refer to section 8.1. “Custom conversion curves” to increase accuracy.

Connection to Equolink 3 software

• Connect the Equostat 3 probe to a PC using the provided probe cable
• Start the Equolink 3 software , and click  for the software to detect the Equostat  3 probe. Click the “New” button at the bottom of the screen.
• Select the suitable value for the surface curvature. For zero surface curvature, select “off”.
• Select the material group applicable to the test piece (see section 7.2. “Material groups”).
• Select the hardness scale to be displayed (see 7.3. “Hardness scales”).
• Select the number of readings n per measurement series (see section 7.4. “Number of indentation tests per measurement series”).

The user can now start testing the test piece.

Using the Equostat 3 Probe

• Conduct measurements by cycling through the “1. position – 2. press down – 3. release” mechanism:

1. Position the probe on the test piece. Take particular care that the foot is placed on the test piece without wiggling or directly on top of a previous test indentation. It is recommended to hold the probe foot firmly with one hand. When using the clamp, adjust the height of the clamp to accommodate the test piece.
2. Depress the probe body with the other hand through the loading stage, until contact is felt. Hold for approx. 2-3 seconds, following the instructions shown on the display.
3. Slowly release the load. To perform another reading, repeat this cycle.

• After the last of the n readings, the hardness average and further statistics of the measurement series are displayed.

Note: The guidance dialogue on the Equotip 3 screen or in the Equolink 3 win-dow, respectively, will indicate the appropriate timing for the load- release cycle.

• If possible, follow the standard practice of “Hardness testing with por-table measuring instruments operating with mechanical penetration depth”, as described in the standard DIN 50157-1 (metallic materials). Alternatively, use ASTM B724 (aluminium materials), or other applicable standards.
• If no standards are available at hand, the user is recommended to aver-age a minimum of n = 3…5 readings of the test piece taken at an indentation distance of 1 to 3 mm (0.04 to 0.12”) from each other. Do not carry out an indentation in an area that has already been deformed by another indentation.

Testing Curved Surfaces
The instrument in the standard foot setup works properly only when the foot sits securly on the surface (i.e. without wiggling), and if the diamond indenter is precisely aligned 90° to the test surface. If convex surfaces are tested, replace the standard foot by a specially suited foot for testing cylindrical surfaces, or by using the measuring clamp, respectively (see “Accessories” or contact your local Proceq representative).

Testing Welds and Heat-Affected Zones (HAZ)
For weld testing, or the testing of HAZ, the combination of the Equostat 3 with the Equotip impact device DL has proven particularly useful to cover a wide range of geometries. The Equostat 3 helps to cover the range of particularly thin-walled test pieces, whereas the Equotip impact device DL is used for rigid / tightly-fixed test pieces. The user yields best aiming accuracy using the long foot or the tripod. On curved test pieces, the special feet can be used to adjust to the cylindrical geometry. Even and smooth sample surfaces are of the essence.

 Overview of the Equostat 3

The Equostat 3 is typically used for testing the hardness of metallic surfaces. As a result of its compact design, measurements can be carried out quickly, on the spot and in any position and direction. The device measures the difference of indentation depths at defined loads. Based on calibration curves, this difference is used to calculate

• the Vickers hardness HV (when using Material Group 1),
• the Rockwell hardness HRB (when using Material Group 6).

Conversions of the determined hardness to different hardness scales are provided, for example to Rockwell (HMMRC, HRA, HRB, HRC, HR15N, HR15T), Brinell (HB), Vickers (HV), and Shore (HS), as well as to tensile strength (Rm), according to the conversion standards ISO 18265 or ASTM E140, and according to customer selections (please refer to 7.1 Measuring Method, Conversion Standard)
Note: ‘MM’ stands for ‘mobile mechanical’ measurement, an ancillary that is re-quired by the German standard DIN 50157 to explicitly denote the lower applied loads, sharper indenter shape and shorter loading times during a measurement. The different denomination is formal, i.e. the HMMRC results should be very close if not equal to stationary HRC readings.

Application Examples

• portable testing applications on both small and large test pieces
• fully documented hardness tests on assembled machines or steel and cast constructions, as well as on small parts and awkward part geometries
• testing of metallic work pieces when the test indentation should be as small as possible
• quality control measurements for quick determination of a particular heat treatment condition
• fast testing of numerous measuring points to examine the change of hardness over large areas
• automated testing
• laboratory tests which require very high repeatability

Danger:
Other applications could be dangerous. The manufacturer is not liable for dam- age caused by improper use or incorrect operation.

In accordance with the power manager settings, the instrument automatically switches to idle or standby mode.
Note: In case the device is powered on but the screen does not respond to pressing any keys, a reset can be carried out by pressing the on / off key for approx. 20 sec.

Charging the battery
A fully charged battery is sufficient for at least 8 hours of operation. The operation time can be extended by reducing the brightness of the backlight or switching it off. If the battery becomes weak, the battery indicator on the screen starts flashing until the indicating device eventually switches off. To recharge the battery, use the Equotip 3 AC power adapter. The charging status of the battery is indicated by the green status LED beside the on / off key:

Flashing

• LED mostly on
• LED mostly off

| Indicating device is in standby state.

• Battery is charging
• Battery is not charging

LED continuously off| Battery is fully charged or not inserted.

Danger:
To fully recharge the battery, the device needs approx. 8 hours of charging. Danger: Only use the Equotip 3 AC power adapter (12 V, 1.25 A) to charge the Equotip 3 indicating device.
Note: Only the Equotip 3 Li-Ion battery can be charged internally in the Equotip 3 indicating device.

• The integrated Li-Ion battery allows over 500 complete charge / discharge cycles. If the operation time of the battery is shortening notably, a new battery should be ordered. The battery lifetime has expired when the LED does not go off even though the battery has been charged for several days.

Optimizing performance of the battery system

As with many other electronic instruments using a rechargeable battery, the battery system will perform best when it is first completely discharged and then completely charged.
Thus, in order to calibrate the battery indicator  of the Equotip 3, Proceq recommends con-ducting a complete discharge-charge cycle, as follows:

1. Upload the latest OS (version ≥ 1.2.2) and firmware (version ≥ 1.6.0). Verify on the first screen when booting up, or in the help menu, that these have been successfully loaded.
2. Disconnect the mains power supply.
3. Set backlight to the highest level.
4. Select the menu item Config >> System settings >> Power manager… and set both entries under “Battery powered” to “never”.
5. Wait until the battery is discharged completely. Make sure that the Equotip 3 is running. It will shut down at the end of the discharge process.
6. Connect the mains power supply.
7. Switch off the backlight.
8. Completely recharge the battery. The instrument must be switched on during the charging process.
9. Wait until the battery is charged completely. Make sure that the Equotip 3 is running. It is best to open the “Show system info” box.
10. Check if the timestamps under “Bat. charged” and “Bat. discharged” entries in the “Sys-tem info [Battery]” dialog have been set.
11. Restore the Power manager settings, as desired.

Note: The recalibration of the battery indicator can take 24 hours, depending on the initial charging state of the battery before the cycle is started.

Performance check / daily verification

1. Verify that the Equostat 3 test block is supported by a solid worktop to ensure it is fix and free of vibrations. Use a test block the hardness of which is similar to that of the test object. Proceq offers test blocks at three hardness levels.

2. Peel off the protective sticker off the surface, and store for subsequent reuse. Ensure that the testing surface is clean, smooth and dry. If required, use acetone, isopropanol or the
   like to remove any residues of adhesives or dirt (no water!).

3. Power on: Press the on / off button for approx. 2 seconds to switch on the Equotip 3 indicating device.

4. Display: Select “Bar graph” or “Basic mode” from the “View” menu (see “Views”).

5. Settings: Turn off the diameter correction by pressing the F1 key. Select the hardness scale, in which the Equostat test block is calibtrated in, by pressing the F3 key. Select the number of indentation tests n per measurement series by pressing the F4 key.

6. Perform 10 indentation tests, which ideally should be evenly distributed across the entire test block (see section 2.5. “Testing Procedure”).

7. The average set point hardness of the block is engraved on the surface. The measured average should coincide with the target range. (If not, please refer to sections 4. “Getting Started” and 13. “Troubleshooting”.)

Your new Equostat 3 is fully operational and you can now continue with your measurements.

• Bar graph: Shows the measurements as a bar graph. This view is practical when the hard-ness profile of a test piece is measured.
• Multiple series bar graph: Multiple measurement series are displayed.
• Set bar graph range: To overview the relevant hardness range only, the viewing range can be fixed.
• Scale bar width: Controls the width of the bars that represent the readings.
• Basic mode: The last reading / mean value is displayed as a large number. This view is handy when the screen is viewed from a distance, or when the device is used in a dark surrounding like a factory floor.
• Signal graph: The actual measurement signal from the probe is displayed. This view is convenient to demonstrate the measurement principle in training sessions, to study the signal shape for consistency, or for signal studies in laboratory studies.
• Conversion function: Measurements are displayed as data points on a graph of the active conversion function. This view permits the user to relate the scattering range of the read-ings in the converted hardness unit to the data scatter in the original penetration depth measurement (in μm).

Note: The large number on the display can either give the mean value or the last reading of the measurement series, respectively. Use the key to switch between the two modes.

Backlight

• The backlight can be adjusted to pre-defined lighting levels simply by pressing the  key repeatedly.

Note: Navigate to “Config” – “Display” to adjust the LCD contrast and the back-light.

Sound
The Equotip 3 indicating device can be configured (“Config” – “System settings” – “Sound…”) to emit audible alarms in case of pre-defined events. For example, when a signal cannot be evaluated or limits are exceeded, alarm signals prompt the user to repeat the measurement or to reject the part, respectively. Also, completion of a measurement series is acknowledged through a validation signal. This feature is useful especially when rapid series testing is con-ducted.

On-Screen Help

• During operation, the user may refer to the Equotip 3 on-screen help library. It is accessible via the “Help” submenu or through pressing the  key to receive context sensitive help.

Operating language
The desired language can be selected in “Config” – “Language”.

Settings **

**

• When starting up, the Equotip 3 is in the same state as it was before the last shutdown. To adjust the settings, either press the “context sensitive function” keys or the “open menu” keys, respectively.

Note: If   symbol is shown instead of the  symbol, unplug the probe cable for approx. 2 seconds and plug back in to re-establish the connection.

• If the automatic storage option is turned on, all data are automatically stored as original penetration depth measurements (in μm) with additional information such as diameter correction, time and serial number of the used devices. When transferring the data to the PC using the Equolink 3 software, they can then be converted to any other scale without accumulation of conversion errors, since the stored original penetration depth value is used as the original value for all conversions.

Measuring Method, Conversion Standard

• There are two measuring methods implemented in Equostat 3, following DIN 50157 or ASTM B724 as described in section 2.1. “Test principle”. The default measuring method is DIN 50157, as it is applicable to testing all metals. It generally yields the more consistent results. Users have the option to measure in the ASTM B724 mode whenever ASTM E 140 is chosen as con-version standard and material group 6 (Cast aluminium alloys) is selected.

• Press the key to open the “Config” submenu and select “Equostat settings…”.

• Use the to select the conversion standard. If ASTM E140 is selected, the alternative measurement method according to ASTM B724 can be selected. This mode will then be employed for material group 6 (Cast aluminium allows).

• To exit the selection window hit the key.

Note: In accordance with the selected measuring method, either ISO 18265 or ASTM E140 hardness conversions are applied in the DIN or ASTM method, respectively.

Material groups

To switch between material groups,

• Press the F2 key to select the material group.
• Use the navigation keys to choose a material group.
• Confirm selection with the key. If readings were shown on the display, they will be  converted using the conversion function for the newly selected material group.

Note: Material group selections have no effect on measurements of the Equostat 3 penetration depth difference in μm, as no conversion is applied. In contrast, hardness conversions to other scales show some dependence on the elasto-plastic material properties. Free online material databases and the Equotip 3 on-screen help can be useful to assign your materials to one of the nine material groups. Suitability of conversions for specific materials should be verified on calibrated test pieces before use. For further advice, please contact Proceq.

• For a given hardness scale, the dropdown menu only lists the material groups for which conversions are available. If no conversion is available, use a different material group and apply a custom conversion, see section 8.1. “Cus-tom Conversion Curves”.

Hardness Scales

To change the hardness scale using conversion functions from the depth measurement in μm to other scales:

• Press the F3 key to select the hardness scale.
• Use the navigation keys to choose a hardness scale.
• Confirm selection with the key. If readings were shown on the display, they will now have been converted to the newly selected hardness scale.

Note: For a given material group, the dropdown menu only lists the hardness scales for which conversions are available.

• Measurements for certain steels can be converted to tensile strength according to DIN EN ISO 18265.
• Converted hardness values may vary depending on the conversion stan-dard selected (ISO 18265 or ASTM E140).

Number of Indentation Tests per Measurement Series

In order to end a measurement series, the user can close the series using the function key “Close”. Alternatively, if a fixed number of indentation tests, e.g. n = 5, is desired for each series, automatic termination of the series after 5 recorded values can be set. To set a fixed number of indentation tests,

• Press the F4 key.
• Use the +/- buttons to select the desired number of indentations.
• To exit press the key.

Note: “Bad” measurement readings may be erased from a test series using the navigation keys and then pressing the function key “Remove”. Make sure readings are only removed in accordance with the relevant quality guidelines, or restrict this function using user profile settings, respectively.

• Following closure of a test series, the user may decide to add further readings or replace “bad” readings simply by pressing the function key “More”. The function key “New” clears the display to start a new series.

File Name of Measurement Series

In order to define the alphanumeric file name of the measurement series,

• Press the key.
• Use the navigation keys to input the filename.
• To exit press the key. The file name can be used as the reference to the tested produc-tion lot / part. The file name identifies the test series after downloading the data to a PC using Equolink 3 or the Equotip 3 Automation Package, respectively.

Note: Ensure that the floppy-disc symbol for automatic storage is displayed if the data needs to be saved. If this function is switched off, the measured data is lost once the series has been closed.

• Keyboard-style or SMS-style input modes can be used. The configura-tion can be changed through “Config” – “User interface”. A USB keyboard, a USB mouse or a USB scanner may be connected to the connection ports (use the USB type A socket). A USB keyboard, mouse, etc. can be connected to the Equotip 3 indicating device at the same time as Equostat 3 using standard USB hubs to multiply the USB port.
• When a measurement series has been closed and the series is stored, the last alphanumeric character of the file name is automatically incremented. A different file name can be defined manually by pressing the key.

Limits

In order to define lower and upper hardness limits for a tested part,

• Press the key to open the “Measurement” submenu and select “Limits…”.
• Use the navigation keys and the key to activate the upper and / or lower limit. The limits can be changed by pressing the keys.
• Confirm selection with the • key. The range of “good” readings is now highlighted in grey, and values outside the limits are flagged with a “+” or “-” next to the values.

Advanced Settings

The most frequently used advanced functionalities of the Equotip 3 indicating device are de-scribed below.

Custom Conversion Curves
Minimizing Conversion Errors
Provided the material group is selected correctly, conversion errors will not normally exceed ±2 HR for Rockwell scales and ±10 % for HB and HV. In most cases, the conversion error is significantly lower. If higher accuracy is required, or if the alloy under test is not covered by one of the built-in conversions, the Equotip 3 indicating device provides a variety of methods to define material-specific conversions. These custom conversion curves can be set up through “Config” – “Customer Conversions”, and used through the “hardness scales” dialog, see section 7.3. “Hardness scales”.

Methods for Setting Custom Conversions
The Equotip 3 provides three methods to accomplish custom conversions (example μm → HB):

• One-point method: The penetration depth difference in μm (using Equostat 3) and the hardness in the desired scale HB (using a stationary Brinell hardness tester) are deter-mined for a reference work piece. A standard conversion function μm –> HB is then adapted through vertical offset until the measured reference data pair lies on the shifted curve.
• Two-point method: Two reference test pieces are tested, one as soft and one as hard as possible to find two data pairs μm / HB. A standard conversion function μm –> HB is then adapted through adding a straight line until both of the measured reference data pairs lie on the tilted curve.
• Conversion polynomial: If a custom conversion needs to be applied throughout a wide hardness range, several reference test pieces shall be measured to find a stable basis for interpolation. Up to 5th order polynomials can be programmed into the Equotip 3 indicat-ing device by defining the polynomial coefficients Ai in HB (μm) = A0 + A1·μm + A2·μm2 + A3·μm3 + A4·μm4 + A5·μm5.

Example of a Custom Curve

• The data pairs ( 34.9 μm / 75.4 HB) and (56.2μm / 136 HB) were measured on two refer-ence test pieces made from “Al-Cu alloy”.
• To measure “Al-Cu alloy” in future using an adapted μm –> HB conversion, the original μm –> HB conversion curve for “Aluminium Alloy” is tilted using the two data points. In this example, the special conversion is defined as valid for the range 34.9μm to 56.2μm.
• Once this curve has been created, it can be selected via material group “Customer de-fined” – “Al-Cu alloy”, using the hardness scale “HB Brinell”.

Measuring Reference Test Pieces

• The test piece surfaces must be prepared very carefully.
• Prior to each measurement series, the proper working order of Equostat 3 shall be verified against the Euqostat 3 calibrated test block.
• The functioning of the static hardness testing machine (HV, HB, etc.) shall be verified against respective test blocks of the corresponding measuring scale and range.
• To obtain a pair of comparative values, the mean values from at least 10 to 15 μm-measurement values and from 3 values from the static test shall be calculated. These values shall be obtained from proximate positions in a small measuring area.

Data Printout and Digital Output
The Equotip 3 is equipped with USB, Ethernet and RS 232 ports by default:

• USB type A: Connector socket for Equostat 3, keyboard, mouse, barcode scanner, printer, etc.

• USB type B: Refer to the separate operating instructions “Equolink 3 Software” included on the Equotip CD.

• Ethernet: Configuration is accessed through “Config” – “System settings” – “IP set-tings…”. Enter the IP address of the device or use the DHCP option.

• RS 232 (serial): The RS 232 interface can be used for printing, but due to its speed limitations it is not suitable for device updates.

• Printer setup: Printers can be connected via USB type A, RS 232, or network (ethernet), respectively. Configuration is accessed through “Config” – “System settings” – “Print-er…”. Various printers can be selected from a list. If “Autoprint at end of series” has been enabled, the indicating device will automatically print a protocol each time a measurement series is closed. Alternatively, a protocol of the current series can be printed at any time using “Measurement” – “Print series” – “Long protocol” or “Short protocol”.

Note: Communication via Ethernet connection is faster than USB.

User Profiles with Password Protection

Minimizing Operating Errors and Enhancing Efficiency
Super-users can define user profiles via “Config” – “User profiles”.

User profiles can be config-ured to serve purposes such as:

• Test piece specific device settings: For different work pieces, the needs for hardness testing may vary. For example, the hardness of small and large test pieces can require the use of Equostat 3 with conversion to HB and impact device G with conversion to HB, respectively. In this case, two user profiles “Small test pieces” and “Large test pieces” can be defined to start up with the settings and restrictions that apply to the respective work pieces. This permits a rapid change of settings at minimal risk for making mistakes.
• User-specific device settings: Two users who test in different surroundings can configure their own preferences for how the data should be displayed on the screen (views bar graph, basic mode etc.) and for display settings (backlight, contrast).
• Access restrictions: Password protection is an effective tool where it is important to trace back test execution to particular users. Also access to confidential data can be restricted.

Example of a User Profile

• User “Dietmar Leeb” has been given restricted access rights for measurements.

• On the one hand, Dietmar Leeb is permitted to adjust the setting of the surface diameter correction during the test. Also, Dietmar Leeb is free to take as many indentations per
  measurement series as he believes is required to make a sound statement.

• On the other hand, Dietmar Leeb is required to test according to the DIN standard and thus cannot change the measuring method, and neither can he change the settings for material and scale, as he is assigned to only report the hardness of aluminium parts in Brinell. For these parts, also the pass/fail limits are fixed.

Data Evaluation

Statistics

Statistics for measurement series of up to 9999 indentations are calculated automatically:

• Number of indentation tests n = 10, lower limit 63.0 HRC, upper limit 69.5 HRC.
• The bar graph provides a convenient overview confirming that all the 10 readings fall within the limits.
• The series statistics (average x, standard deviation s, Max/Min, value range R) are shown in the upper screen section.
• The single readings are shown in the lower screen section.

PC Application Software Equolink 3
More Equotip functionality is made available through the Equolink 3 PC software. A separate manual “Equolink 3 Software” is included on the Equotip CD.

Maintenance and Support

Proceq is committed to providing a complete support service for this instrument. It is recommended that the user obtain available updates and other user information regularly through www.proceq.com.

Regular Device Check
Performance checks (see section 4.6. “Performance Check / Daily Verification”) of the instrument should be carried out at least once a day or at the latest after 1000 tests. In the case of infrequent use, carry out the check before the beginning and at the end of a test series. In addition, have the device calibrated by an authorized Proceq Service Center once a year.
Note: The unit is working properly when the average is within the target range. If the average deviates from the setpoint value by more than ±2 HRC, see section 13. “Troubleshooting”.

Cleaning

• Equostat 3 probe:

1. Unplug the cable and unscrew the probe foot.
2. Take the rubber protector off the probe.
3. Clean the probe with a soft cloth. If needed, use isopropanol to remove severe stains. Use a cotton pad to clean inaccessible areas.
4. Reassemble.

• Indenter: Clean the indenter with an isopropanol-soaked soft cloth.
• Feet, measuring clamp: Clean carefully with a soft cloth, use isopropanol if needed.
• Housing of indicating device: Clean the display and housing with a clean, dry cloth after use. Also clean the connector sockets with a clean, dry brush.

Note: Never immerse the device in water or clean it under running water. Do not use abrasives, solvents or lubricants to clean the device.

• If the factory floor presents a dirty, dusty and rough environment, the user is advised to slip the rubber protector over the probe, and to use an Equotip 3 protective carrying pouch.

Storage
Only store the Equostat 3 in the original packaging and in a dry room free of dust.

Updating the Equotip 3 Firmware and Operating System Connect the device to the computer
Updates can be done using Equolink 3 as follows:

• From the respective folder on the Equotip CD, install Equolink 3 to your PC.
• Select the “Device” menu from the menu bar and select “PqUpgrade” in the submenu, or click the symbol in the toolbar.
• Select “Express” and confirm with “Next”.
• Select the device type and confirm with “Next”.
• In the “Choose Communication Type” dialog box, select the type of communication used between the Equotip 3 and PC, and then click “Next”.
• In the “Device search result and selection” dialog box, make sure the serial number of the device in the drop-down field is the device to be updated, and then click “Next”.
• PqUpgrade will now search the Proceq servers for any available updates.
• Follow the on-screen instructions to finish the update.

Note: Before updating the firmware, the measured data should be saved to the PC.

• The “Custom” update is recommended for advanced users only.

Troubleshooting

Incorrect Measurements or Failed Performance Check

• During the performance check, if the average deviates from the setpoint value by more than ±2 HRC:

1. Make sure that the foot sits securely on the probe or the probe securely in the clamp, respectively.
2. Clean the indenter, paying close attention especially to the front part (diamond) and to the screw thread. Replace the indenter if necessary, or replace the test block if there is insufficient space for additional tests.
3. Clean the probe, as described in section 12.2. “Cleaning”.
4. Check the mounting and wear of the stand and clamp. Check for deposits. Clean or replace if necessary.
5. If the instrument still shows excessive deviations: return the device to an authorized Proceq Service Center for recalibration / inspection.

• An incorrect conversion or a wrong setting for the diameter correction may have been selected. Refer to section 7. “Settings”.
• The selected conversion scale is not in the permissible range (“noCnv”). Select another hardness scale.
• Individual values are scattered very widely or are continuously too low.
  1. The testing location is insufficiently prepared. Carefully prepare the testing location for the indentation, see section 2.2. “Test piece preparations”.
  2. The test is conducted while the device is not held vertically on the surface, which will generally give a warning on the guidance dialog. This may occur especially when using the long foot or the tripod. Try using another foot, or take more care to align the probe vertically to the surface.
  3. Test piece is insufficiently supported. Prepare the test piece for the test e.g. through supporting it with a larger metal piece.
  4. Make sure the probe does not tilt / move on the surface. See section 2.6. “Testing curved surfaces”.

Note: Do not re-grind test blocks or try to use non-Proceq indenters. This will impair accuracy and may also deteriorate functionality of the Equostat 3.

No Reading displayed or No Probe Connection

• Check the connection of the probe cable. Unplug for 2 seconds and plug back in.
• Check if genuine Equostat 3 parts and accessories are used.
• Check for tight seating of the support foot on the thread of the probe.
• Press down the indenter with the ball of your hand to make sure that the mechanism is moveable. If not, the mechanics of the probe may be jammed or defective. If so, contact an authorized Proceq Service Center.

Empty Display

• If nothing is indicated on the display, activate the device through pressing any key.
• If nothing happens, the instrument may be too cold and/or the battery may be discharged. Take the device to a warmer place and/or charge the battery.

Battery

• If the indicating device does not switch on, recharge the battery using the Equotip 3 AC power adapter, see section 4.4. “Charging the Battery”.
• The battery can be replaced with another Equotip 3 Lithium-Ion battery, or with 3 standard C cell batteries (Alkaline, NiCd or NiMH). Lithium-Ion batteries can be recycled.
• Recalibration of lifetime indicator: Refer to 4.5. “Optimizing Performance of the Battery System”.

Note: Do not remove or insert the Lithium-Ion battery while the device is running with an external power supply. This leads to an unwanted reset of the lifetime indicator, which subsequently results in wrong battery status indication.

• If the operation time of the battery is shortening noticeably, order a new battery. The battery lifetime has expired when the LED does not go off even though the battery has been charged for several days.

Danger:
Only use the Equotip 3 AC power adapter (12 V, 1.25 A) to charge the Equotip 3 indicating device.

Error messages

• “The application contains no version information…”:

Possible causes:

1. Something fatal went wrong during device update, e.g. a power loss occurred.
2. The flash memory of the device is defective.

Countermeasures:

1. Delete the update by pressing the “yes” button when the error message “The application contains no version information…” is displayed. Then retry updating the device.
2. If this error persists, contact an authorized Proceq Service Center.
   • “Boot menu”:
   • If critical files in the Equotip 3 indicating device have been corrupted, the boot menu can help to reset the device to a functioning state.
   • For this, select “Start Default Application”.

Note: The boot menu can be accessed by simultaneously pressing and during the booting sequence in case the indicating device does not boot up properly anymore.

Slowing Down of Device
The device reacts very slowly, e.g. keys must be pressed for several seconds until the key press is registered, or measurements are displayed with a delay of several seconds.

• The more you write to the flash memory (e.g. measurement series, device power up & shutdown cycles, device updates), the more frequently this condition can occur.
• The flash disc is automatically cleaned up when there are too many invalid sectors. This is a common and necessary task.
• Wait some minutes, or continue working under this special condition.

Device Reset
If the indicating device does not react, a reset must be carried out to correct faults. Press and hold the on / off key for approx. 20 seconds. Wait for approx. 5 seconds, and then press the on / off key again to switch on the indicating device.
