Model UT513: OPERATING MANUAL
Warning
Do not use the Meter if it is damaged or metal
part is exposed. Look for cracks or missing
plastic.
Be careful when working above 33V rms, 46.7V
ac rms or 70V DC. Such voltages pose a shock
hazard.
Discharge all loading of circuit under test after
measuring high voltage.
Do not change battery when the Meter is in
wet environment.
Place test leads in proper input terminals.
Make sure all the test leads are firmly
connected to the Meterís input terminals.
Make sure the Meter is turned off when
opening the battery compartment.
Caution
When performing resistance tests, remove all
power from the circuit to be measured and
discharge all the power.
When servicing the Meter, use only the same
model number or identical electrical
specifications of test leads and power adaptor.
Do not use the Meter if the battery indicator
(
) shows a battery empty condition. Take
the battery out from the Meter if it is not used
for a long time.
Do not use or store the Meter in an
environment of high temperature, humidity,
explosive, inflammable and strong magnetic
field. The performance of the Meter may
deteriorate after dampened.
Soft cloth and mild detergent should be used
to clean the surface of the Meter when
servicing. No abrasive and solvent should be
used to prevent the surface of the Meter from
corrosion, damage and accident.
Dry the Meter before storing if it is wet.
When carrying out insulation measurement,
do not contact the circuit under test.
