6. Testing the instrument
Due to the underlying measurement principle,
nocalibrationoftheinstrumentisrequired.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
congurationofthisorganizerisxedandcannot
be changed.
The unit then switches to the measurement mode.
Place the instrument on the test tile and perform
three measurements.
The values printed on the reference tile are the
correctedreadings.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
(seeChap.16).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
inuences,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).
