Safety

•  Read the following safety information carefully before attempting to 

operate or service the meter.

•  To avoid damages to the instrument do not apply the signals which 

exceed the maximum limits shown in the technical specifications tables.

•  Do not use the meter or test leads if they look damaged. Use extreme 

caution when working around bare conductors or bus bars.

•  Accidental contact with the conductor could result in electric shock.
•  Use the meter only as specified in this manual; otherwise, the protection 

provided by the meter may be impaired.

•  Read the operating instructions before use and follow all safety Information.
•  Caution when working with voltages above 60V DC or 30V AC RMS. 

Such voltages pose a shock hazard.

•  Before taking resistance measurements or testing acoustic continuity, 

disconnect circuit from main power supply and all loads from the circuit.

Safety Symbols:
