1. SAFETY INFORMATION
l
Read the following safety information carefully before
attempting to operate or service the meter.
l
To avoid damages to the instrument do not exceed the
maximum limits of the input values shown in the technical
specification tables.
l
Do not use the meter or test leads if they look damaged.
l
Use extreme caution when working around bare conductors
or bus bars. Accidental contact with the conductor could
result in electric shock.
l
Use the meter only as specified in this manual; otherwise,
the protection provided by the meter may be impaired.
l
Read the operating instructions before use and follow all
safety information.
l
Caution when working with voltages above 60VDC or
30VAC RMS. Such voltages cause a shock hazard.
l
Before taking resistance measurements or testing acoustic
continuity, disconnect circuit from main power supply and
all loads from circuit.
Safety symbols
Caution refer to this manual before using the meter.
