State-of-the-art technology and the
reference-beam principle mean that
calibration is needed only infrequently.
We recommend a calibration interval
of two months.
Calibration is also necessary:

ambient temperature (for example,
after moving the unit to a new site)
s IF0LEASE2ECALIBRATEAPPEARS
on the display (for example, after
stored calibration values have been
modified).
To ensure accurate calibration, use
only original standards from
BYK-Gardner.
Do not touch the reference surface.
Protect it against scratching.
Even with careful treatment, ambient
conditions may alter a standard’s va-
lues over time. For that reason, have
Customer Service check your stan-
dards regularly (once a year) against
primary standards.
Make sure the values displayed du-
ring calibration match the data for the
standards you use, in order to avoid
mixing up or accidentally changing
the calibration values (see Section
5.3).
To calibrate:
CAUTION: Make sure the
calibration standards are clean
and free from scratches!
