WARNING
Use caution with voltages above 30 V ac as a shock hazard may exist.
FOR USE BY COMPETENT PERSONS
Anyone using this instrument should be knowledgeable and trained about the risks involved with
measuring voltage, especially in an industrial setting, and the importance of taking safety
precautions and of testing the instrument before and after using it to ensure that it is in good
working condition.
The single-pole phase testing is not appropriate to determine whether a line is live or not. For this
purpose, the double-pole voltage test is always required.

part of the building's low-voltage mains installation. Typical short-circuit current is < 50 kA.
Measurement category IV:
Measurement category IV is applicable to test and measuring circuits connected at the source of
the building's low-voltage mains installation. Typical short-circuit current is >>50 kA.
