A. Introduction
This product is a battery-powered, true-rms, auto ranging digital clamp multimeter with a 6000 counts
LCD display and a backlight.
B. Safety Information
To avoid possible electrical shock, fire, or personal injury, please read all safety information before
you use the product.
(1) Do NOT exceed the “maximum value” indicated in the Specification.
(2) Examine the connection of the test leads and the insulation of the product before measuring
voltage higher than 36V DC or 25V AC.
(3) Disconnect the test leads from the circuit before changing the mode。
(4) Misuse of mode or range can lead to hazards, be cautious. “OL” will be shown on the display when
the input is out of range.
(5) Safety symbols:

D. Instruction
(1) Front Panel（see the picture on the right）
1. Jaw
2. Flashlight
3. Jaw release
4. Hold / Inrush Current / Peak Hold
HOLD: To press this button once and you will see
“HOLD” on the display;
Inrush current: To press this button twice
and you will see “INRUSH” on the display;
Peak hold: To press this button twice after
connecting test leads to the Terminals and you
will see “Peak HOLD” on the display;
5. Power / Select
Power: Press this button for more than 2 seconds
to turn it on / off.
Select: Press this button for switching functions
after connecting test leads to the Terminals.
6. Frequency / NCV: Press this button over 2 seconds
into NCV mode and exit from release.
7. LCD display
8. COM: Common terminal for all measurements.
9. : Input terminal for voltage, resistance, capacitance, temperature, frequency,
continuity, diode measurements and judging N/L wires.
10. Wire to be measured
11. Marked position
(2) Measure AC/DC Voltage
1. The minimum voltage of this product is 0.8V. When the measured voltage is higher
than 0.8V, the product will display the reading;
2. Connect the black test lead to the COM Terminal and connect the red test lead to
the Terminal;
3. The DC or AC voltage will be matched automatically;
4. Touch the probes to the correct test points of the circuit to measure the voltage;
5. Read the measured voltage on the display.
*Caution:
a. Do not measure voltage that exceeds the MAX Value as indicated in the
Specifications;
b. Do not touch high voltage circuit during measurements.
(3) Measure AC Current Only
1. Turn power switch on
2. Push the jaw release and center the wire within the clamp jaws (as in the picture).
The wire should be in the marked position to keep measurement accuracy.
3. Read the measured current on the display.
