Calibration

The meter should be calibrated (zero point / multi-point calibration) each time a new sample is measured. The material properties and the radius of curvature of the uncoated calibration surface should be as similar as possible to those of the sample. Make sure to choose similar calibration/measuring points, particularly when measuring corners and edges of small parts. The radius of curvature, the minimum material thickness and minimum measurement range stated in chapter 2.1 should be observed. The meter offers zero-point and multi-point calibration. Each memory group has its individual zero-point and multi-point calibration. The values previously measured are not affected by a new calibration.

Zero-point calibration

A zero-point calibration must be made on an uncoated calibration surface. If it is not possible to calibrate the meter on the sample, please use the calibration plates that come with the meter. A zero-point calibration is recommended where the measuring accuracy is ±(2 % + 1 μm). To carry out a zero-point calibration, follow these steps:

Press and hold until you hear three beep sounds and ”ZERO“ is displayed.
Place the probe on the uncoated calibration surface and lift it as soon as you hear a beep sound.
Repeat that step several times in order to get a mean value.
Press to leave zero-point calibration.

Multi-point calibration

The meter’s multi-point calibration feature allows up to 4 calibration points to be considered. When making a single-point calibration, the calibration value should be as similar as possible to the expected measurement value. When making a multiple-point calibration, the expected measurement values should be somewhere between the calibration values. The permissible maximum measurement error is ±(2 % + 1 μm).

If you have already made a calibration, you have to delete the existing calibration values first, as described in chapter 5.1.3. If not, start with the next step.
In measure mode, press to open the calibration dialogue which can be enabled or disabled in the calibration settings.
If you have previously made a zero-point calibration, the zero point will be used as the first calibration point. If not, follow the steps described in chapter 5.1.1.
Place one of the included standard foils on the uncoated calibration surface.
Place the sensor on the foil and remove it when you hear a beep sound. The reading will now be displayed.
Use the keys to adapt the reading to the actual foil thickness (flashing value) and confirm with . The calibration point will then be displayed in the dialogue box (non-flashing value). You can cancel the procedure with .
Repeat these steps if you wish to get all four calibration points. Use a different standard foil for each calibration point.
Press to exit the multi-point calibration.

Delete calibration

To start a new calibration, you can delete the calibration points recorded during zero-point calibration and during multi-point calibration individually. Follow these steps:

Press to enter the “Root“ menu.
Use the keys to navigate to “Calibration“ and confirm with .
