Safety Precautions
Be sure to read and follow these instructions !
The Model 136S Conductivity Meters may only be opened
to change the batteries outside hazardous areas. If repairs
are necessary, the meter must be sent in to the factory.
Never operate the remote interface or printer within haz-
ardous areas.
When using the meter in hazardous areas, watch for elec-
trostatic charges! For example, never wipe off the meter
with a dry cloth. Observe the relevant regulations concern-
ing ESD.
Whenever it is likely that the protection has been impaired, the meter shall
be made inoperative and secured against unintended operation.
The protection is likely to be impaired if, for example:
❏

❏
the meter fails to perform the intended measurements
❏
after prolonged storage at temperatures above 70
°

Before recommissioning the meter, a professional routine test according to
EN 61 010-1 shall be performed. This test should be carried out at our fac-
tory.
