VII. Tester maintenance
Maintenance of the lens:
-
Avoid to put the fingers on the lens to prevent dirtiness
-
Clean it if necessary (with soapy water or with a windscreen washer product)
-
If your lens is cracked or scratched too heavily you have to replace it through a service
company.
Mechanical checking:
-
When operating your tester, check that the bubble of the on-board level remains in its original
position whatever the tester position.
-
In case of the bubble deviates too much, please contact your service company in order a
technician checks your tester and its calibration.
