PIN-142
1. Overview
The multimeter is characterized as slim sized, portable, stable
performance and anti-dropping capacity. Using a 3½ digits LCD monitor it
offers clear readings.
The meters can be used to measure DC & AC voltage, DC current,
resistance, temperature, positive diode voltage fall, hFE parameters for
transistor and continuity and gives excellent performance and exquisite
making as a handy utility instrument.

3. Safety Information
a. The meter is designed according to IEC-1010 concerning electronic
measuring instruments with an over-voltage category (CAT Ⅲ) and
pollution degree 2.
b. Follow all safety and operating instructions to ensure that the meter is
used safely and is kept in good operating conditions.
c. Safety symbols:
important safety information, refer to the operating manual.
Dangerous voltage may be present.
Double insulation (protection Class II)
4. Special Cautions for Operation
a. The meter can be safe only according to standard procedures when
used in conjunction with the supplied test leads. Replace damaged test
leads only with the same model or same electric specifications.
b. To aviod risk of electric shock, do not use the meter without the cover
in place.
c. The range switch should be in the correct position for testing.
d. To avoid electric shock and damaging the instruments, the input
signals should not exceed the specified limits.
e. When measuring TV sets or power switches, attention should be paid
to the possible pulses that may bring destruction to the circuit.
f. The range switch position should not be changed at random during
measurement.
g. Take caution against shocks while measuring voltages higher than
60V DC & 30V AC.
h. The protection fuse should be replaced only with the same type and
same specifications.
