Getting started

Power supply

For power supply, three AAA Alkaline batteries are required. Before replacing the batteries, turn off the meter. The battery compartment is located at the rear side of the meter and fixed with two screws. Loosen the screws, remove the cover, insert the batteries as marked and close the battery compartment by tightening the screws

Preparation

To turn on the meter, press until the display reacts. After charging, the meter will show the measuring screen. To turn off the meter, press . Connect the included probe FN1.5 to the probe socket of the meter. Make sure that the plug is in the right position. The arrow must be visible from the front side of the meter.

Options

To change the standard settings, navigate to the submenu “Options“. Follow these steps:

Press to enter the “Root“ menu.
Use the key to go to “Options“ and confirm with .

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 ERO“ 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 .
Select according to the following subsections (a, b, c) what values you would like to delete.

a) Delete multi-point calibration values

Navigate to “Point Cal“ by using the keys and confirm with .
Use the keys to navigate to “Clear Magnetic“ or ”Clear Magnetic“ as required and confirm with .
A dialogue box opens. Confirm with to delete the calibration values or cancel the procedure with .

b) Delete zero-point calibration values

Use the keys to navigate to “Zero Cal“ and confirm with .
Use the keys to navigate to “Clear Magnetic“ or ”Clear Magnetic“ as required and confirm with .
A dialogue box opens. Confirm with to delete the calibration values or cancel the procedure with .

c) Delete all calibration values

Use the keys to navigate to “Clear All“ and confirm with .
A dialogue box opens. Confirm with to delete all calibration values or cancel the procedure with .

Measurement

Procedure:

First connect the desired probe as described in chapter 4.2.
Make the required device settings (measure mode, group mode, probe mode, speed, etc.) as described in chapter 4.3.
Make a zero-point calibration and a multi-point calibration before the measurement (chapter 5.1).
Place the probe vertically on the surface to be measured. Lift the probe when you hear the beep sound.

To delete other memory groups and values, change the memory group as described in chapter 4.3 and follow the steps above again.

Delete values
Press to enter the “Root“ menu. Navigate to “Recall“ with the keys and confirm with . In the upper left part of the display, you will now see what value of a memory group has been selected (1/4). Select the desired reading with . You can delete that reading by pressing .

Statistics
When making a measurement in measure mode, the current mean value, the maximum and the minimum values will be displayed below the current reading. To view the complete statistics, press first. In the menu that is now displayed, go to “Browse Stat.“ by using the keys and confirm with . You can now see the statistical values of the currently selected memory group. To view the statistics of the other memory groups, change the memory group as described in chapter 4.3 and go back to the statistics function.

The meter creates individual statistics based on the saved readings of each memory group. In the statistics, the number of readings, the mean value, the minimum and maximum values as well as the standard deviation will be displayed. When the memory is full in direct mode, the first reading will be deleted and the new reading will be saved. The statistics will be updated accordingly. When the memory is full in general mode, no new readings will be saved and the statistics will not be updated. If you delete the current reading or all readings of the group, the statistics will update.

Limit settings
Each memory group has its own upper and lower limit value. When changing the memory group, the limit values will be switched automatically. When a limit value is exceeded/fallen below, the red LED on the left will flash. Moreover, a will be displayed when the upper limit has been exceeded or a if the lower limit has been fallen below.

To enter the upper and lower limit value, follow these steps:

Press to enter the “Root“ menu.
