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.
If the value to be measured is unknown, use the
maximum measurement position.

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.
The internal circuit of the Meter shall not be altered
at will to avoid damage of the Meter and any accident.
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
