PEN TYPE DIGITAL MULTIMETER
OPERATOR’S MANUAL
1. Overview
The pen type digital multimeter is characterized at slim size,
portable, stable performance and anti-dropping capacity. Using
6000 counts digit LCD monitor with character 12mm high, they
offer clear readings. With overall circuitry design centering on
large-scale IC A/D converters in conjunction and over-load
protection circuit, the meters give excellent performance and
exquisite making as a handy utility instrument.
The meters can be used to measure DC & AC voltage, resistance,
capacitor, positive diode voltage fall and audible continuity. If the
equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.
2. Panel Layout
1. VΩ: V/ Input test lead.
2. Lamp light.
3. Test lead fixture: Fix the COM test lead.
4. LCD display: 6000 counts digit, full function symbol display.
5. Toggle Switch: Use this switch to select functions and ranges.
6. HOLD key: Press the “HOLD” key to lock display value, and the
“DH” sign will appear on the display, press it again to exit. Press
the “HOLD” key over 2 seconds to light the back light, press it
again for more than 2 seconds to lights off it, it can lights off
automatically after 15 seconds too.
7. REL Key: Press the “REL” key, the meter enters relative
measuring mode, “REL” is displayed on the LCD and the present
reading becomes the reference value and displayed on the display.
Relative measurement REL△ =measurement value-Reference
value. Press it again to exit.
8. SELECT key: This key work on the " " range, press the
key to choose resistance, diode, continuity test or capacitance test,
on the voltage range, change to DC or AC.
9. Protective casing.
10. Battery cover.
11. COM: COM input test lead.
3. Safety Information
3-1 The meter is designed according to IEC-1010 concerning
electronic measuring instruments with an over-voltage category
600V (CAT Ⅲ) and pollution 2.
3-2 Follow all safety and operating instructions to ensure that the
meter is used safely and is kept in good operating condition.
3-3 safety symbols:
Important safety information, refer to the operating manual.
Dangerous voltage may be presence.
Double insulation (protection Class II)
4. Special Cautions for Operation
4-1 To avid risk of electric shock, do not use the meters before the
cover is in place.
4-2 The toggle switch should be right position for the testing.
4-3 To avoid electric shock and damaging the instruments, the
input signals are forbidden to exceed the specified limits.
4-4 When measuring TV set or switched power, attention should
be paid to the possible pulses that may bring destruction to the
circuit.
4-5 Toggle switch position is forbidden to be changed at random
during measurement.
4-6 Take caution against shock in the course of measuring voltage
higher than DC 60V & AC 30V.
4-7 After operation is finished, set toggle switch at OFF to save
battery power.
4-8 If the meter is without usage for long time, take out battery to
avoid damage by battery leakage.
5. GENERAL SPECIFICATIONS
5-1 Max Voltage between input terminal and Earth Ground: CAT Ⅲ
600V.
5-2 Over-range Indication: display “OL” for the significant digit.
