Rules For Safe Operation

Warning
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:
l 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.
l Inspect the test leads for damaged insulation or exposed
metal. Check the test leads for continuity. Replace
damaged test leads with identical model number or
electrical specifications before using the Meter.
l Do not apply more than the rated voltage, as marked on
the Meter, between the terminals or between any
terminal and grounding.
l 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.
l When the Meter working at an effective voltage over 60V
in DC or 30V rms in AC, special care should be taken for
there is danger of electric shock.
l Use the proper terminals, function, and range for your
measurements.
l 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.
l When using the test leads, keep your fingers behind the
finger guards.
l Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, diodes,
current, or capacitance.
l Before measuring current, check the Meter's fuses and
turn off power to the circuit before connecting the Meter
to the circuit.
l 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.
l Remove test lead, temperature probe, RS232C interface
