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).
