General Safety Information
WARNING
– Do not exceed any of the measurement limits defined in the specifications
to avoid instrument damage and the risk of electric shock.
– When working above 30 V
AC
RMS or 60 V
DC
, exercise caution – such
range poses a shock hazard.
– Do not measure more than the rated current and voltage (as marked on
the clamp meter).
– Ensure the test leads are disconnected from the input terminals when
measuring current with the clamp meter. Keep your fingers behind the
hand guard when performing measurements.
– When connecting probes, always connect the common test probe first.
When disconnecting probes, always disconnect the live test probe first.
– Detach test probes from the clamp meter before you open the battery
cover.
– Do not use the clamp meter with the battery cover or part of the cover
removed or loose.
– Replace the battery as soon as the low battery indicator is shown on the
annunciator display. This is to avoid false readings, which may lead to
possible electric shock or personal injury.
– When measuring temperature, keep the thermocouple probe as close to
the meter as possible, and avoid contact with surface above 30 V
AC
RMS
or 60 V
DC
as this will pose shock hazard.
– Do not operate the product in an explosive atmosphere or in the presence
of flammable gases or fumes.
– Inspect the case for cracks or missing plastic. Pay extra attention to the
insulation surrounding the connectors. Do not use the clamp meter if it is
damaged.
– Inspect the test probes for damaged insulation or exposed metal, and
check for continuity. Do not use the test probe if it is damaged.
– Do not service or perform adjustments alone. Under certain condition,
hazardous voltages may exist, even with the equipment switched off. To
avoid dangerous electric shock, service personnel must not attempt
internal service or adjustment unless another person, capable of
rendering resuscitation or first aid, is present.
