using polarity.
2. For checking the charge of the batteries
press and hold the button .
3. The Level of the batteries charging is shown
on the left upper corner of the display as a small
battery icon. The dark battery color means the
batteries is fully charged. During discharging the
battery icon segments disappear consecutively,
from left to the right. One dark segment or
absence of segments means that the batteries
needs recharging. The battery icon is present on
the display in any mode of the device operation.
4. For charging the batteries turn off the device
pressing the button .After that take off
the batteries from the battery compartment and

conditions of use (considerable change of the
temperature, conduction of the material) at first
activation of the probe.
6.4 Average values of measurements
The automatic averaging mode provides a default
calculation of final measurement result in the
arithmetic mean value together with the last
measurements.
6.4.1For switching on the mode of averaging press
and hold button , for more than 2 seconds.
6.4.2On display the following information will
appear:

6.4.4To return from mode with averaging press and
hold button for more than 2 seconds. The
device will return to the usual mode.
6.5 Scales of the measured value
6.5.1For choosing the scale of the measured value
(mm or µm) press .
6.5.2The chosen scale will be indicated on the
display.
6.6 Calibration
To provide an adequate measurement with the
device of the real thickness of the covering calibrate
the device. For it you need to prepare a sample of
the tested part similar or close in geometric,
electrophysical properties and in the type of
mechanical treatment of the tested product.
6.6.1 Setting zero
6.6.1.1 Install the probe perpendicularly on
prepared sample without covering normal to the

0.000; 00.00; 000.0; or 0 will appear on the
display depending on the type of the probe and
used scale.
6.6.1.3 For checking the accuracy of the setting
zero make repeated measurements on the
prepared sample without covering. Reading
must be within the range of 0±2 µm.
Note: Zero setting is recommended for the probe
according to p.6. 5. in the case of changing
conditions of use (considerable change of the
temperature, conduction of the material) at first
activation of the probe.
