A. Introduction
This product is a battery-powered, true-rms, auto-ranging digital multimeter with
a 9999 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:

2a. RANGE/Backlight: 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, turn the
Rotary Switch to another mode and then
turn it back. To turn on the backlight, press
this button for more than 2 seconds; long-
press again to turn off.
2b. SELECT/HOLD: To toggle between different
testing modes (functions), press this button.
To hold the current reading, press this
button for more than 2 seconds and you
will see “HOLD” on the display; long-press
again to turn off.
3. Rotary Switch: To change mode or range

3e. Frequency (low voltage high frequency)/Duty Cycle
3f. DC Current (mA&A)/AC Current (mA&A)
3g. DC Current (μA)/AC Current (μA)
3h. NCV
4. AmA: Input terminal for current (mA&A) measurements.
5. COM: Common terminal for all measurements.
6. VΩHz: Input terminal for voltage, current (μA), frequency, duty cycle, resistance,
continuity, diode, capacitance, and temperature measurements.
(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 DC Voltage (V) Mode, or the DC Voltage (mV) 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.
