Testing the instrument
6. Testing the instrument
Due to the measurement principle, calibration of the
equipment is not necessary. It is recommended,
however, to check the functionality of the instrument
at regular intervals (about once every 3 months). The
reference tile included with delivery is provided for
this purpose.
Select the “Standard” in the Measure menu. The
configuration of this organizer is fixed and cannot be
changed.
The unit then switches to the measurement mode.
Place the instrument on the test tile as shown
above and perform three measurements.
If the values measured on the reference tile are
within the printed tolerance range, the requirements
are met.
If the mean value is not within the desired tolerance
range, try carefully cleaning the test tile. If this
produces no improvement, please contact our
Customer Service department.
Reference tile:
To ensure a precise instrument test, only original
test tiles from the manufacturer should be used.
Their surface must not be touched and must be
protected against scratches. Due to environmental
influences, however, the values of test tiles can
change over the course of time even if they are
handled gently. For this reason, have the test tiles
checked by the manufacturer at regular intervals
(annual checks are recommended). For cleaning the
test tile refer to chapter 17.
