6 Battery replacement
6.1 Batteries should be replaced once the battery symbol is displayed.
6.2 Slide the battery compartment cover 3-8 out of the measurement instrument and
remove the batteries.
6.3 Insert batteries (4 × 1.5 V, AAA/UM-4), paying attention to their polarity.
6.4 If the device is unused for an extended period of time, remove the batteries.
7 Adjustment films
The scope of delivery comprises adjustment films, including various films with differ-
ent measurement ranges which, however, always cover the measurement range of
20 to 2000 µm They are available also as optional accessories, product ATB-US07.
8 Correct measurement of layer thickness using external sensors
Sensor
(orange: F/black: N)
Spring pin for manipulating
Measuring probe
The sensor should be held by the lower pin segment and pressed against the meas-
ured object slightly.
The black, ribbed pin segment moves on the spring. The spring presses the sensor
head against the measured object with a pre-defined force, eliminating any meas-
urement errors in this way.
Moreover, the measurement errors can be avoided by carrying out many test meas-
urements before the first use.
9 General guidelines
9.1 The measurement instrument should always be adjusted using the substrate ma-
terial to be used for the proper measurement instead of the delivered calibration
plate. This will ensure higher measurement accuracy.
9.2 The measuring probe can be worn. The measuring probe service life usually de-
pends on the number of measurements and the roughness of the measured layer.
The probe should always be replaced by qualified specialists.
10 Resetting to factory settings
Resetting to factory settings is recommended in the following circumstances:
— Absolute inability to measure any further;
