The meter is a stable multimeter with 26mm LCD display, driven by battery. It’s
widely used on measuring DCV, ACV, DCA, ACA, resistance, capacitance, diode,
transistor, continuity test and temperature. Ideal for lab, factory and family use.
SAFETY NOTE
The meter meets the standards of IEC1010. Read the operation manual carefully
before operation.
1. Do not input limit over-ranged.
2. The voltage below 36V is safe. To avoid electric shock, check whether the test
leads are connected correctly, whether the insulation is good when measuring
over 36DCV or 25ACV.
3. Remove the test leads when changing function and range.
4. To select correct function and range, beware of error operation.
5. Do not operate the meter if battery case and back cover is not fixed.
6. Do not input voltage when measuring resistance.
7. Remove test leads from test point and turn off the power before replacing battery
and fuse.
8. Safety symbols:
“” indispensably refer to the manual, “ ” GND ,
“ ” double insulation, “” low battery。
NOTE: at 600Ω range, the test leads should be short-circuited, and measure the
down-lead resistance, then, subtract from the real measuring.
WARNING: DO NOT input any voltage at resistance range for safety concern!

circuit under tested, the polarity and voltage of the point which red lead connect
will display on LCD.
NOTE:
1. If the measured voltage is unsure beforehand, the range knob should be set to the
highest range; then, switch to a proper range according to the display value.
2. If LCD displays "0L.", it means over range, the range knob should be set to a
higher range.

1. If the measured voltage is unsure beforehand, the range knob should be set to the
highest range; then, switch to a proper range according to the display value.
2. If LCD displays "0L.", it means over range, the range knob should be set to a
higher range.
3. The value of the AC voltage measured with this meter is True RMS (root mean
square). These measurements are accurate for sine wave and other waves
(without DC offset), square wave, triangular wave and step wave.
3.4 Frequency MEASUREMENT
1. Insert the black test lead to "COM " jack, the red one to V/Ω jack.
2. Set the range knob to a proper AC 750V range, press the " /SEL" key to select
"Hz" measurement mode, connect the test leads across to the circuit under tested.
3. When the measured signal ≥100V and the frequency is within the range of
45Hz~1000Hz,the LCD of the meter will display frequency value of the voltage.
3.5 DCA MEASUREMENT
1. Insert the black test lead to "COM " jack and the red one to "mA" jack(max.
600mA) ,or insert the red one to "20A" jack(max. 20A).
2. Set the range knob to a proper DCA range, connect the test leads across to the
circuit under tested. The current value and polarity of the point, which red lead
connect will display on LCD.

NOTE:
1. If the measured current is unsure beforehand, the range knob should be set to a
higher range; then, switch to a proper range according to the display value.
2. If LCD displays "0L.", it means over range, the range knob should be set to a
higher range.
3. Max. input current is 600mA or 20A (subject to where red lead insert), excessive
current will blow the fuse. Be careful when measuring. Continuously measuring
large current may heat the circuit, affect the accuracy, or even damage the meter.
3.6 ACA MEASUREMENT
1. Insert the black test lead to "COM" jack and the red one to "mA" jack(max. 600mA),
or insert the red one to "20A" jack (max. 20A).

to the highest range, then set to a proper range according to the displayed value.
2. If LCD displays "0L.", it means over range, the range knob should be set to a
higher range.
3. Max. input current is 600mA or 20A (subject to where the red lead insert to),
excessive current will blow the fuse. Be careful when measuring. Continuously
measuring large current may heat the circuit, affect the accuracy, or even damage
the meter.
4. The value of the ACA measurement with this meter is True RMS (root mean
square). These measurements are accurate for sine wave and other waves
(without DC offset), square wave, triangular wave and step wave.
3.7 RESISTANCE MEASUREMENT

the resistance under measured.
NOTE:
1. If the resistance value being measured exceeds the max value of the range
selected, LCD displays "0L."; thus, the range knob should be set to a higher range.
When the resistance is over 1MΩ, the meter may take a few seconds to stabilize.
This is normal for high resistance readings.

2000F.
2. If LCD displays "0L." , it means over range.
3. Before measuring, LCD display might not be zero, the residual reading will be
decreased gradually and could be disregarded.
4. When measuring large capacitance, if creeps seriously or break capacitance, LCD

of the diode positive volt drop.
3. Press the key "HOLD" to select the " "Connect the test leads to two points of
the measured circuit, if buzzer sounds, the resistance is lower than approx.
(50±20)Ω.

3.12 NCV test (non-contact voltage detection)
Turn the rotary switch to NCV position, and place the top of the meter approach the
conductor. If the meter detects the AC voltage(≥AC 90V 50/60Hz), the indicator
LED will be on, while the beeper will sounds alarms at different frequencies.
Note:
1. Voltage may still remain in the absence of any indication. The operator shall not
rely on non-contact voltage detector to check the presence of voltage. The
detection operation may be affected by various factors, including socket design,
insulation thickness and type.
2. When the voltage is input into the meter's input terminal, the voltage sensor LED
may be on as a result of induced voltage.
3. External sources of interference (like flashlight and motor) may trigger non-contact
voltage detection.

sleeping mode. To restart the meter, press “power” button twice for back to working
status.
