Work Mode:
The work mode must be set in advance for each measuring and calibration mode. You can choose either echo-echo mode (E-E) or pulse-echo mode (P-E). Echo-echo mode should be used if you want to measure coated workpieces as the coatings (varnishes/paints) will be ruled out to avoid material thickness errors. Pulse-echo mode is used for all other measurements, especially for the detection of faults and cavities and for calibration of the meter. The selected mode will be displayed on the main screen.

Calibration

Zero point calibration

Note: For a zero point calibration, the meter must be in pulse-echo mode (P-E). A zero point calibration is carried out by calibrating the meter to the correct zero point by using the internal calibration disc. A zero point calibration is recommended whenever the device is restarted and when the probe is changed.

Procedure:

1. Connect the probe as shown in chapter 4.2.3.
2. Press to enable zero point calibration.
3. Apply some coupling gel to the calibration disk.
4. Evenly press the probe onto the calibration disk until theprogress bar is complete.
5. Remove the probe from the calibration disk.
6. Your meter is now successfully zero point calibrated.

Sound velocity calibration
Note: Before doing a one- or two point calibration, the varnish or paint layers must be removed from the workpiece to be measured. In the following sub-chapters, you can find three possibilities to perfom the calibration.
Calibration to a known sound velocity
For this calibration procedure, the user has to know the correct sound velocity of the measured workpiece. In chapter 6, you can find a chart of materials and their sound velocities.

Procedure:

1. Press F1 to select the velocity.
2. Use the keys F1 UP  and F2 UP to select the decimal place and set the sound velocity with the keys UP DOWN . You can also select some preset sound velocities from a chart by pressing the Zero key.
3. Press F3 UP to confirm your entry.

Calibration to a certain material thickness (one-point calibration)
For this calibration procedure, a workpiece of the material to be measured is needed. The exact material thickness of the workpiece must be known or must be measured with an external meter.

Procedure:

1. Make a zero-point calibration as described in chapter 5.2.1.
2. Apply some coupling gel to the workpiece.
3. Evenly press the probe onto the workpiece. (The coupling status and a material thickness value should now be displayed)
4. Remove the probe when a stable value has been reached. If the value changes while the probe is removed, repeat step 3.
5. Press UP DOWN  to be able to enter the nominal thickness.
6. Select the decimal place with F1 UP and F2 UP and set the material thickness with the UP DOWN keys.
7. Confirm your entry with F3 UP. The meter will display the main screen and show the calculated sound velocity in the upper part of the display. The meter is now ready to measure.

Calibration to a certain material thickness (two point calibration)
For this calibration procedure, two workpieces of the material to be measured are needed. The exact material thickness of the workpieces must be known or must be measured with an external meter.

Procedure:

1. Make a zero point calibration as described in chapter 5.2.1.
2. Apply some coupling gel to the workpiece.
3. Evenly press the probe onto the workpiece. (The coupling status and a material thickness value should now be displayed)
4. Remove the probe when a stable value has been reached. If the value changes while the probe is removed, repeat step 3.
5. Press UP DOWN  to be able to enter the nominal thickness.
6. Select the decimal place with F1 UP and F2 UP and set the material thickness with the UP DOWN keys.
7. Press Zero to calibrate the second point. Then repeat steps 2 to 6 with the second workpiece.
8. Confirm your entry with F3 UP. The meter will display the main screen and show the calculated sound velocity in the upper part of the display. The meter is now ready to measure.

Measurement

Procedure:

1. Before starting a measurement, carry out a calibration (5.2).
2. set the work mode in line with the criteria described in chapter 5.1.
3. Apply some coupling gel to the workpiece.
4. Evenly press the probe onto the workpiece (the coupling status and material thickness value should now be displayed in white letters).
5. If a correct measurement is not possible, double-check the coupling gel and evenly and firmly press the probe onto the workpiece. If the problem persists, try a different probe (different size/ frequency).
6. If desired, you can save the measured value, as described in chapter 5.4.4.
7. Four measurements per second are made. When the probe is removed, the last reading will remain displayed.

Further functions View Mode
You have three different options to view measured values: normal mode, scan mode, difference mode
Normal mode: In normal mode, only the current material thickness value will be displayed.
Scan mode:
In scan mode, the material thickness value will be displayed as in normal mode. In addition, the minimum and maximum values will be displayed. The minimum and maximum values can be reset by means of the On/off key BUTTON.

Difference mode:
In this mode, the material thickness value is displayed along with the difference to the set nominal thickness T0.
The nominal thickness T0 of the workpiece must be set in advance. To do so, go to the main menu by pressing F3 UP and select “Test Settings” where you can find the “Nominal Thickness” setting. You can select the decimal place with F1 UP  and F2 UP and with UP DOWN , you can set the nominal thickness. Confirm your entry with F3 UP.

Limit value setting
In order to see whether the material thickness value is within the tolerance, a top limit and a bottom limit can be set. When the limits are exceeded/fallen below, the reading will be shown in red instead of green when the probe is removed. To set the limit values, go to the main menu with F3 UP Setup and select “Test Settings“. Here, you can find the settings “Bottom Limit“ and “Top Limit“. With F1 UP and F2 UP, you can select the decimal place and the limit can be set with DOWN. Confirm your entry with F3 UP.

Resolution
You can select one of these three resolutions: 0.1 mm / 0.01 mm / 0.001. If you select 0.001 mm, the surface of the workpiece should be very smooth. When the surface is coarse, a low resolution is recommended. To set the limit values, go to the main menu with F3 UP Setup and select “Test Settings“. Here, you can find the resolution setting. Select the desired resolution with F2 UP. Confirm your entry with F3 UP.\
Memory Manager Save
When you press the Save key, the current reading will be saved to the selected data set as the last data record.
