DIGITAL MULTIMETER
OPERATOR'S MANUAL
1. Overview
The multimeter is characterized at slim size, portable, stable performance and
anti-dropping capacity. Using 4000 counts digit LCD monitor with character
25mm 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, DC & AC current,
resistance, capacitor, frequency, duty cycle, Non Contact AC Voltage (NCV)
detection, positive diode voltage fall and audible continuity.
2. Panel Layout
1. Test lead fixture: Fix the test lead.
2. CDS sensor: The CDS sensor can reaction to the ambient brightness range,
then automatically control the LCD backlight to lighten or go out.
3. NCV detection area: Non Contact AC Voltage (NCV) detection area.
4. NCV red light: Non Contact AC Voltage (NCV) detection red light.
5. NCV green light: Non Contact AC Voltage (NCV) detection green light.
6. LCD display: 4000 counts digit, full function symbol display.
7. SELECT key: This key work on the "
diode or continuity test, on the current range, change to DC or AC; If press and
hold SELECT key to power on, "Auto Power Off " function will be disabled.
8. NCV Key: Press and hold the "NCV" key, the meter enters Non Contact AC
Voltage (NCV) detection, the NCV green LED light will light up, free it to exit.
9. HOLD key: Press the "HOLD" key to lock display value, and the "DH" sign will
appear on the display, press it again to exit.
10. 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.
11. Hz/% Key: On "ACV/ACA" or "Hz" range, press the "Hz/%" key, you can
choose the Frequency or Duty Cycle measurement.
12. Rotary Switch: Use this switch to select functions and ranges.
13. COM: COM Input Jack
14. 10A: 10A Input Jack
15. VΩmA: V/μAmA/Hz/

3. Safety Information
3-1 The meter is designed according to IEC-1010 concerning electronic
measuring instruments with an over-voltage category 600V (CATⅢ) 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 The meters can be safe only according to standard procedures when used in
conjunctions with the supplied test leads. To replace damaged test leads with
only the same model or same electric specifications.
4-2 To avid risk of electric shock, do not use the meters before the cover is in
place.
4-3 The range switch should be right position for the testing.
4-4 To avoid electric shock and damaging the instruments, the input signals are
forbidden to exceed the specified limits.
4-5 When measuring TV set or switched power, attention should be paid to the
possible pulses that may bring destruction to the circuit.
4-6 Range switch position is forbidden to be changed at random during
measurement.
4-7 Take caution against shock in the course of measuring voltage higher than
DC 60V & AC 30V.
4-8 Protection fuse should be replaced only with same type and same
specification.
4-9 After operation is finished, set function switch at OFF to save battery power.
