A. Introduction
This product is the world's first 9999 counts palm-size auto-ranging digital
multieter. The product is battery-powered with true-rms, 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.

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 botton for more than 2 seconds; long-
press again to turn off.
2b. SELECT/HOLD: To toggle between different
testing modes (functions), press this botton.
To hold the current reading, press this
botton for more than 2 seconds and you
will see “HOLD” on the display; long-press

(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.

4. Read the measured capacitance value on the display once the reading is stablized.
*Caution:
a. Disconnect circuit power and discharge all capacitors before you test capacitance.
(9) Measure Frequency and Duty Cycle
1. Connect the black test lead to the COM Terminal and connect the red test lead to
the VΩHz Terminal;
2. To measure high voltage low frequency, turn the rotary switch to the DC Voltage(V)
Mode; press SELECT twice to toggle to the Frequency Mode or press SELECT three
times to toggle to the Duty Cycle Mode. To measure low voltage high frequency,
turn the rotary switch to the Frequency Mode; press SELECT once to toggle to the
Duty Cycle Mode;
3. Touch the probes to the desired test points of the circuit;
4. Read the measured frequency/duty cycle value on the display.
Warning：
1. Do NOT exceed the “maximum value” indicated in the Specification;
2. Do NOT input voltage at the Current Mode, the Resistance Mode, the Diode
Mode, the Continuity Mode, or the Temperature Mode;
3. Do NOT use the product when the batteries or the battery cover is not placed
properly;
4. Turn off the product and remove the test leads from the test points before
changing batteries or fuses.
