Notes on measurement

• When the device is turned on, the minimum distance from the metal should not be less than 10 cm.

• To ensure measurements are as precise as possible, calibrating the
  device with the uncoated original test piece material to be measured is recommended before performing each measurement. If necessary, correct using zero calibration, one-point calibration or two-point calibration.

• If the uncoated original material is not available, use a material that is as similar as possible or the reference material supplied.

• The measurement device has basic calibration settings for ferromagnetic and non-ferromagnetic metals. Using different kinds of metal bonds/alloys, and performing measurements with high precision within defined ranges, may require the measurement device to be calibrated.

• The absolute measuring accuracy is highly dependent on the alignment of the reference films, which should be clean and free from damage.

• Measuring accuracy levels must take the following tolerances into account: device, reference film, original material/alloys, surface roughness/bending radius, contamination, handling (tangential setting down without vibrations).

• Separate calibration processes are performed for Fe and NFe. The calibration settings are retained when the device is turned off.

• Averaging and statistics may increase the calibration accuracy. To achieve this, repeat zero calibration, one-point calibration and two-point calibration at least three to five times.

• If errors take place in the calibration process, the individual calibration must be deleted before the process is repeated (see item, 7, Current data).

• If deviations that cannot be explained arise, the memory must be erased completely (see item 7, Group data).

• Performing multiple statistical measurements increases measuring accuracy; additionally, statistics for multiple distributed points can be used to determine the average coating thickness.

• Interference fields may affect measurement.

• During measurement, keep the device as straight, tangential and still as possible.

• Make sure the surfaces of the material, sensor and reference films are clean. Dust, for example, may result in serious inaccuracies.

Zero calibration

The zero point setting should be checked and, if necessary, corrected before each measurement.

Checking/Calibrating the zero point

Menu > Options > Measure mode > Single mode

Exit the menu: press key 1 twice

3| Perform measurement (see item 12): measurement on uncoated material (original material or reference material)
| Value within tolerance (see technical data): check complete; no calibration necessary
| Value outside tolerance (see technical data): Calibration required: press and hold the ZERO key (3); repeat steps 1-3 to check

One-point and two-point calibration

One-point calibration calibrates a coating thickness as close to the expected measured value as possible.
Two-point calibration defines a second coating thickness in order to increase the measuring accuracy. The expected measured value should be as close as possible to the mid-point between the calibration points (cal 1 and cal 2).
Multiple films may be combined for greater coating thicknesses.
Example: expected coating thickness: 75 µm

• Calibration point 1:
  Measurement with reference film 50 µm ± 1%

• Calibration point 2:
  Measurement with reference film 101 µm ± 1%

Checking calibration

1. Zero calibration; see item 10
2. Place the required reference film(s) on the uncoated material (original material or reference material)
3. Measure the reference thickness
   Value within tolerance (see technical data): Check complete;
   no one-point or two-point calibration required
   Value outside tolerance (see technical data):
   One-point and two-point calibration required; see item 11.2

Perform one-point and two-point calibration

1. Zero calibration; see item 10 One-point calibration (cal 1)

2. Turn the device off/on

3. Set the measuring mode:
   Menu > Options > Measure mode > Single mode Exit the menu: press key 1 twice

4. Set the working mode:
   Menu > Options > Working mode > Direct / Group 1 – 4 (Calibration can be defined individually for each mode.) Exit the menu: press key 1 twice

5. Delete the previous calibration data in the applicable working mode: see item 7

6. Set the calibration mode:
   Menu > Calibration > Enable > ESC
   („cal“ and „zero“ appear on the display)

7. Place the required reference film(s) on the uncoated material (original material or reference material)

8. Measure the reference thickness

9. Set the reference film thickness using the keys

10. Briefly press the ZERO key (3) („cal 1“ and „zero y“ appear on the display)
    Two-point calibration (cal 2)

11. Repeat steps 7-10 („cal 2“ and „zero y“ appear on the display)
    Complete one-point or two-point calibration: Menu > Calibration > Disable > ESC

To increase the calibration accuracy, repeat steps 7-11 at least three to five times using the same reference films that were used previously.

Performing measurement 

During measure-ment, keep the device as straight, tangential and still as possible.

Reset to factory settings

The measurement device can be reset to the factory settings and the basic calibration settings in order to delete all measured values, settings and calibration values.
To do so, follow these steps:

1. Switch off measuring device
2. Press the keys „ON/OFF“ and „ZERO“ at the same time.
3. Let go of the „ON/OFF“ key and keep ZERO“ pressed.
4. After starting, confirm the reset by responding either „Yes“ or „No“ to the prompt.

Average / Standard deviation

For several measurements, the average _x indicates the average value, while the standard deviation (Sdev) gauges the average deviation of the individual measurements from this average value. More significant standard deviations indicate a more scattered series of measurements.
For normal measurement distributions

• 68% of the measurements are within: ± (1*Sdev),
• 95% of the measurements are within: ± (2*Sdev),
• 99% of the measurements are within: x ± (3*Sdev)

Notes:

• The statistics data must be deleted before each new measuring task (first measurement = no. 1).
• In the case of rough, contaminated surfaces, averaging may improve the measurement result.
• Statistics can be used to determine the average coating thickness on extensive measurement areas; to do this, set at least 10-20 measuring points distributed across the entire area.

Error messages

USB data transfer

With the software provided on the CD it is possible to transfer the recorded data to a PC and to use the data for further processing and documentation. Load the CD in the drive and follow the installation routine. After successful installation, start the application. Connect one end of the supplied USB cable to the mini-USB port of the device and the other end to a free USB port on your computer.
For further information on how to use the software, refer to the software manual on the DVD that contains a detailed description of the functions.

Information on maintenance and care
Clean all components with a damp cloth and do not use cleaning agents, scouring agents and solvents. Remove the battery(ies) before storing for place. longer periods. Store the device in a clean and dry place.

Calibration
The meter needs to be calibrated and tested on a regular basis to ensure it produces accurate measurement results. We recommend carrying out calibration once a year.
