16.2 Cleaning
We recommend to have the instrument checked and calibrated by Zehntner every
two years. Furthermore you should clean the measurement opening regularly using
the supplied microfiber cleaning cloth. Remove the front plate with calibration
standard before cleaning. Should you not be able to sufficiently clean it with the
supplied microfiber cleaning cloth, use a little bit of window cleaner.
Clean the aluminium housing with a clean soft tissue and a commercial cleaning
agent like window cleaner.
Do not use strong acids or alkaline liquids.
The housing may 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.
The instrument consists of delicate optical 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 shoulder bag.
Make sure that the ZRS 6060 is turned off and unplugged from the battery
charger before maintenance.
During cleaning take care that under no circumstances cleaning liquid flows
into the interior of the instrument. The function of electrical or optical
components could be impaired.
Never immerse the unit in water or in other fluids: Danger of short circuit.
