Simple tests are described in the following which you can carry out yourself in
the case of malfunction. In the case of more difficult faults in individual func-
tions, please contact our service personnel. The tests described here are not
meant to lead you to carry out maintenance work yourself but to provide our
service personnel with information which is as accurate as possible.
Testing the vibrometer is limited to such tests in which the housing does not
have to be opened. Opening the housing without authorization invalidates the
warranty.
If required, please contact our service department. Based on your fault
description, further procedure will be determined.
If the vibrometer has to be sent back for repair, always use the original pack-
aging and enclose an exact description of the fault.
