7 Calibrating the instrument
7.1 Calibration Information
Standards
The instrument is supplied with a white calibration
standard and a cyan and effect checking reference.
Black calibration is done internally by the
instrument.
Mount the test tiles at the position intended for the
instrument test.
Cyan and effect check are recommended to be done
every day.
White calibration must be accomplished at least
every month.
During the white calibration it must be ensured that
the bottom plate is pressed in for 4.5 ± 1 mm from
the zero position. This guarantees that the standard
is aligned flat and the pins are calibrated properly,
i.e. a proper positioning in the measurement plane
is ensured.
To ensure a precise instrument test, only original
checking standards 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
checking standards can change over time even if
they are handled gently. For this reason, they
should be checked by the manufacturer at regular
intervals (annual checks are recommended).
