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 carry out the measurement when the Meter’s back case and battery
compartment are not closed to avoid electric shock.
Do not input higher than 600V between the two Meter’s input terminal to avoid
electric shock and damages to the Meter.
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.
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.
When using the test leads, keep your fingers behind the finger guards.
Disconnect circuit power and discharge all high-voltage capacitors before testing
resistance, continuity and diode.
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.
When servicing the Meter, use only the same model number or identical electrical
specifications replacement parts.
