User Manual
A. Introduction
This product is a battery-powered, true-rms, auto-ranging digital multimeter with
a 8000 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.

2a. HOLD & Backlight
To hold the current reading, push this button
and you will see “HOLD” on the display; push
again to cancel.
To turn on the backlight, push this botton for
more than 2 seconds; long-push again to turn
off.
2b. SELECT
To toggle between DCV/ACV, DCmV/ACmV/,
Resistance/Continuity/Diode/Capacitance,
Frequency(with low voltage)/Duty Cycle,
DCA/ACA, DCmA/ACmA, DCμA/ACμA, or
℃/℉, press this botton.

4. 10A: Input terminal for current (A) measurements.
5. mA/μA: Input terminal for current (mA and μA) measurements.
6. COM: Common terminal for all measurements.
7. VΩHz: Input terminal for voltage, frequency, duty cycle, resistance, continuity,
diode, capacitance,and temperature measurements.
8. RANGE: push this botton 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.
9. REL: the product allows relative measurements for the Modes of Voltage, Current,
and Capacitance; push this button to enter the relative measurements mode;
push again to exit.
10. MAX/MIN: push the botton once to measure the MAX Value; push twice to
measure the MIN Value; push three times to measure the difference between
the two values; to exit the mode, push the botton for 2 seconds.
11. Hz%: push this button when the product is at the AC Voltage (V) Mode to enter
the Frequency (with high voltage) /Duty cycle Mode.
