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.
