Display description

Key description

Power supply

To start using the meter, first insert 2 x 1.5 V AA batteries into the battery compartment on the back. Make sure the polarity is correct when inserting them.
The meter can also be supplied with power via the micro USB port. Thus, the coating thickness gauge can be operated via the USB port of a computer, for example.

On / off

To switch the meter on/off, press and hold the key for more than 1 second. When the meter is not in use, it will automatically turn off within 3 minutes.

Measurement

To make a measurement, place the tip of the sensor on the surface to be measured. A measured value will be displayed directly. Make sure that you place the sensor on the sample vertically and quickly. The meter will detect automatically whether the base material is magnetic (Fe) or non-magnetic (nFe). During a measurement, the sensor must not be moved, otherwise incorrect measurements may occur. To carry out further measurements, place the sensor on the next measuring spot.

Important:
In order to obtain the best results, it is important to take measurements on a smooth and non-slip surface.
Do not impact the sensor head too forcefully on the test object, otherwise you could damage the probe.

Continuous measurement
To perform a continuous measurement, place the sensor on the object to be measured. A measured value will be displayed. Now keep the sensor on the current measuring spot for three seconds. The continuous measurement starts automatically. To stop the continuous measurement, lift the sensor.

Important:
Do not make continuous measurements on sensitive surfaces to create sequences, otherwise you could damage the surface.
Do not carry out continuous measurements on rough surfaces as this could damage the sensor.

Calibration

To perform a calibration, the meter has various functions.

• Factory calibration
• Zero point calibration
• One-point calibration
• Five-point calibration

In order to obtain the most accurate measurement result over the entire measuring range, a five-point calibration is recommended. A calibration of magnetic (Fe) and non-magnetic substrates (nFe) is independent on each other. After each calibration, check the measured values again with the references. If the measured values are still not within the accuracies, repeat the calibration if necessary.

Zero point calibration
To perform a zero point calibration, press the key. Now place the sensor on the corresponding zero reference. When “Lift probe up” appears on the display, remove the sensor from the reference. You will then be asked if you want to accept the calibration. Press the key to save the change. To discard the setting, press the key.

One-point calibration
To perform a 1-point calibration, first go to the calibration menu and select “1-point calib”. Now place the sensor on the corresponding zero reference. When “Lift probe up” appears on the display, remove the sensor from the zero reference. Now place a foil reference on the zero reference. Now carry out a measurement of the reference by positioning the probe on the foil. When “Lift probe up” appears on the display, remove the sensor from the reference. The display will now show the measured value. With the arrow keys, you can now set this value to the calibration reference. Confirm the set value with the key. You are then asked whether you want to accept the calibration. Press the key to save the change. To discard the setting, press the key.

Five-point calibration
To perform a five-point calibration, first go to the calibration menu and select “5-point calib”. Now place the sensor on the corresponding zero reference. When “Lift probe up” appears on the display, remove the sensor from the zero reference. Now place a foil reference on the zero reference. Now carry out a measurement of the reference by positioning the probe on the film. When “Lift probe up” appears on the display, remove the sensor from the reference. The display will now show the measured value. With the arrow keys, you can now set this value to the value of the calibration reference. Confirm the set value with the key. The second calibration point will follow now. Now use another calibration reference and repeat the calibration procedure until you reach the last calibration point. Then you are asked whether you want to accept the calibration. Press the key to save the change. To discard the setting, press the key.
Important: When instructed to lift the probe, lift the probe quickly and place it 30 cm away from the reference before changing the reference film.

Data group

With this coating thickness gauge, the measured values are saved automatically. Various data groups are available for this purpose. To make settings to the data memory, go to the menu under the item “Data Group”. Here, you can make the following settings:

Course (History)	Here you can view the last measured values belonging to the set measuring group.
Selected group (Select Grp XXX)	Here you set the current measuring group. If you make settings in the menu item “Data group”, these always refer to the data group selected here. The measured values are also saved in the data group selected here.
Delete last value (Remove latest)	With this function, you can delete the last measured value.
Delete group (Erase group)	The entire measuring group is deleted here.
Erase memory completely (Erase all)	Here, you can clear the entire memory.

Limit value alarm

To set limit values, first go to the “limit alarm” menu. Under the item “Alarm on”, you can activate the limit alarm function. You can set the limits as follows:

Upper limit value (Up limit)	Here, you can set the upper limit value.
Lower limit value (Low limit)	Here, you can set the lower limit value.

If the measured value is within the limit range, the LED indicator briefly flashes in green. If the measured value is outside the limit values, the LED indicator briefly flashes in red. The display shows whether the current measured value is too high or too low.

Convert unit

To change the unit, go to the menu. Under the item “Unit”, you can choose between the units µm and millimetre.

Backlight

The backlight switches on and off automatically. It is not possible to adjust this.
