PIN-142 MANUAL

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.

2. Panel Layout

① LCD Display: 3½ digits, character 16mm high

② Data-hold Switch (HOLD)

③ Back Light Button Switch: Press this button to switch back light on

and off. If the battery is weak, the light will be dimmed.

④ Rotary Switch: use this switch to select functions and ranges

⑤ 10A -input Jack, Temp (-) & COM -input Jack, Temp (+) & V Ω mA

-input Jack

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.
