The symbol indicating separate collection for electrical and
electronic equipment.
The RESPONSIBLE BODY shall be made aware that, if the
instrument is used in a manner not specified by the
manufacturer, the protection provided by the instrument may
be impaired.
The finger or any part of your body shall not be beyond
the barrier of the test probe when measuring.
Individual protective equipment must be used if
HAZARDOUS LIVE parts in the installation where
measurement is to be carried out could be ACCESSIBLE.
The following safety information must be observed to insure
maximum personal safety during the operation at this meter.
Do not operate the meter if the body of meter or the test lead
look broken.
Check the main function dial and make sure it is at the correct
position before each measurement.
When making current measurements ensure that the circuit not
“live” before opening it in order to connect the test leads.
Do not perform resistance, capacitance, temperature, diode

and continuity test on a live power system.
Do not apply voltage between the test terminals and test terminal
to ground that exceed the maximum limit record in this manual.
Exercise extreme caution when measuring live system with
voltage greater than 60V DC or 30V AC.
Change the battery when the “ ” symbol appears to avoid
incorrect data.

6. MAINTENANCE
1) Before open the battery cover or bottom case, disconnect
both test lead and never uses the meter before the battery cover
or bottom case is closed.
2) To avoid contamination or static damage, do not touch the
circuit board without proper static protection.
3) If the meter is not going to be used for a long time, take out
the battery and do not store the meter in high temperature or high
humidity environment.
4) Repairs or servicing not covered in this manual should only by
qualified personal.
5) Periodically wipe the case with a dry cloth and detergent. Do
not use abrasives or solvents on the meter.
