Meter.
z Do not apply more than the rated voltage, as marked on the Meter,
between the terminals or between any terminal and grounding.
z 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.
z 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.
z Use the proper terminals, function, and range for your measurements.
z If the value to be measured is unknown, use the maximum
measurement position.
z 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.
z When using the test leads, keep your fingers behind the finger guards.
z Disconnect circuit power and discharge all high-voltage capacitors
before testing resistance, continuity, diodes.
z Before measuring current, check the Meter's fuses and turn off power to
the circuit before connecting the Meter to the circuit.
z Replace the battery as soon as the battery indicator
a low battery, the Meter might produce false readings that can lead to
electric shock and personal injury.
z When servicing the Meter, use only the same model number or identical
electrical specifications replacement parts.
z The internal circuit of the Meter shall not be altered at will to avoid
damage of the Meter and any accident.
z 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.
z The Meter is suitable for indoor use.
z Turn the Meter off when it is not in use and take out the battery when
not using for a long time.
z Constantly 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.
