5 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.
6 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.
7 Measurement
To make a measurement, place the tip of the sensor on thesurface 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.
7.1 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.

9 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.

9.1 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.
9.2 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.
9.3 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.
