To avoid possible electric shock or personal injury,
and to avoid possible damage to the Meter or to the
equipment under test, adhere to the following rules:
Warning
Before using the Meter inspect the case. Do not use
the Meter if it is damaged or the case (or part of the
case) is removed. Look for cracks or missing plastic.
Pay attention to the insulation around the connectors.
Inspect the test clips for damaged insulation or
exposed metal. Check the test clips for continuity.
Replace damaged test clips with identical model
number or electrical specifications before using the
Meter.
Do not apply voltage to the Meter.
The rotary switch should be placed in the right
position and no any changeover of range shall be
made during measurement is conducted to prevent
damage of the Meter.
Do not apply more than 30Vrms between the
terminals and the grounding to avoid electric shock
and damage to the Meter.
Use the proper terminals, function, and range for
your measurements.
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.
Disconnect circuit power and discharge all high-
voltage capacitors before testing resistance,
continuity, capacitance or diodes.
Replace the battery as soon as the battery indicator
appears. With a low battery, the Meter might
produce false readings that can lead to electric shock
and personal injury.
