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:
zBefore 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.
zInspect 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.
zDo not apply more than the rated voltage, as
marked on the Meter, between the terminals or
between any terminal and grounding.
zThe rotary switch should be placed in the right
position and no any changeover of range shall
be made when measurement is conducted to
prevent damage of the Meter.
zWhen the Meter is 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.
zUse the proper terminals, function, and range
for your measurements.
zDo 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.
zWhen using the test leads, keep your fingers
behind the finger guards.
zDisconnect circuit power and discharge all high-
voltage capacitors before testing resistance,
continuity, diodes, current or capacitance.
zBefore measuring current, check the Meter’s
fuses and turn off power to the circuit before
connecting the Meter to the circuit.
zReplace 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.
zRemove test leads, point contact temperature
probe and RS232C interface cable from the Meter
and turn the Meter power off before opening the
Meter case.
zWhen servicing the Meter, use only the replacement
parts with the same model or identical electrical
specifications.
zThe internal circuit of the Meter shall not be
altered at will to avoid damage of the Meter and
any accident.
zSoft 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.
zThe Meter is suitable for indoor use.
zTurn the Meter off when it is not in use and take
out the battery when not using for a long time.
zConstantly check the battery as it may leak when
it has been using for some time, replace the
battery as soon as leaking appears. A leaking
battery will damage the Meter.

protection circuit.
zThe test lead has distributed capacitors during
measurement, it has more attenuation effect against
high frequency. Therefore,when testing higher than
1MHz frequency signal, it is recommended to perform
the test using HF-transmitting cable which should be
as short as possible.
zWhen Hz measurement has been completed, discon
-nect the connection between the testing leads and
the circuit under test and remove the testing leads
away from the input terminals.
