is turned off and unplugged from battery charger before
maintenance except for charging.
The instrument consists of delicate optic and electronic precision parts. Do not drop it
and protect it from shocks, moisture and dust. Please store the instrument including its
accessories in the transportation carrying case.
16.2
Cleaning
We recommend that the instrument is checked and certified by Proceq once a year. Otherwise
clean the instrument periodically using water- and oil-free compressed air (max. 1.5 to 2 bar), or
wipe the exit window on the bottom of the optics housing with a soft brush.
The exit window is coated with a special anti reflection coating that should not be damaged. If
the soft brush is not sufficient for cleaning the window, you may use a soft paper tissue and
window cleaning liquid.
The optics housing
must not be opened under any circumstances
since the
measuring geometry would be misaligned. The measuring geometry can only be
adjusted by means of special testing equipment in our factory.
