User Manual
A. Introduction
This product is a battery-powered, true-rms, auto-ranging digital clamp meter
with a 6000 counts, LCD display and 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.

this button.
7. RANGE: press this button to enter the manual
range; each push increases the range; when
the highest range is reached, next push will go
back to the lowest range; to exit the manual
range mode, press the button for 2 seconds.

8. COM: Common terminal for all measurements.
9. VΩHz: Input terminal for voltage, frequency, resistance, continuity, diode,
capacitance, temperature, current (no more than 6000 μA), and duty cycle
measurements.
10. HOLD: To hold the current reading, press this button and you will see “HOLD” on
the display; press again to cancel. To turn on the backlight, press this button for
more than 2 seconds; long-press again to turn off.
(2) Measure AC/DC Voltage
1. Connect the black test lead to the COM Terminal and connect the red test lead to
the VΩHz Terminal;
2. Turn the rotary switch to the AC/DC Voltage Mode;
3. Press SELECT to toggle between AC/DC;
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.
