DIGITAL INSULATION TESTER

INSTRUCTION MANUAL

SAFETY INFORMATION

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.
