The multimeter is characterized at slim size, portable, stable performance and anti-dropping
capacity. Using 6000 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, temperature, transistor hFE, Non Contact AC Voltage (NCV) detection,
positive diode voltage fall and audible continuity.
1 NCV detection area: Non Contact AC Voltage (NCV) detection area.
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 red light: Non Contact AC Voltage (NCV) detection red light.
4 NCV green light: Non Contact AC Voltage (NCV) detection green light.
5 LCD display: 6000 counts digit, full function symbol display.
6 SELECT key: This key work on the " " range, press the key to choose resistance,
diode or continuity test, on the voltage or current range, change to DC or AC, on the
range, change to ℃ or ℉ test; If press and hold SELECT key to power on, “Auto
Power Off ” function will be disabled.
7 RANGE Key: Press the “RANGE” key, the meter enters manual range mode, press it more
than 2 seconds again, return to auto mode.
8 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.
9 Hz/Duty Key: On “ACV/ACA” or “Hz” range, press the “Hz/Duty” key, you can choose the
Frequency or Duty Cycle measurement.
10 HOLD key: Press the “HOLD” key to lock display value, and the “DH” sign will appear on
the display, press it again to exit.
11 MAX/MIN key: Press the “MAX/MIN” key to lock MAX, MIN or MAX-MIN value, and the
“MAX”, “MIN” or “MAX-MIN” sign will appear on the display, press it over 2 seconds to exit.
12 Rotary Switch: Use this switch to select functions and ranges.

3-1 The meter is designed according to IEC-1010 concerning electronic measuring instruments
with an over-voltage category 1000V (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.
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
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.
4-10 If the meter is without usage for long time, take out battery to avoid damage by battery
