care should be taken as there is danger of electric shock.
•Do not touch the probes to a voltage source when the test leads are connected to the
current terminals.

5OPERATING MANUAL
•Connect the common test lead before the live test lead and remove the live test lead
before the common test lead.
•Do not use a current measurement as an indication that a circuit is safe to touch. A voltage
measurement is necessary to know if a circuit is hazardous.
•Do not use the HOLD function to measure unknown potentials. When HOLD is turned on,
the display does not change when a dierent potential is measured.
•When using the test leads, ensure leads are fully seated and keep your ngers behind the
nger guards.
•To avoid electric shock, injury, or damage to the meter, disconnect circuit power and
discharge all high-voltage capacitors before testing resistance, continuity, diodes, or
capacitance.
•Before measuring current, check the meters fuses’and turn o the current to be tested
before connecting the meter to the circuit. After connecting the circuit reliably, turn the
current to be tested on.
•Replace the battery as soon as the battery indicator “ ” appears. With a low battery,
the meter may produce false readings that can lead to electric shock and personal injury.
•Do not alter the meter and use only as specied, or the protection supplied by the meter
can be compromised.
•Use a soft cloth and mild detergent should to clean the surface of the meter when
performing general maintenance. No abrasives or solvents should be used in cleaning;
this is to prevent the surface of the meter from corrosion, damage and accident.
•Turn the meter o when it is not in use. Remove the batteries if the meter is not used for
an extended period of time. If the batteries are not removed, battery leakage may result.

AC VOLTAGE MEASUREMENT
WARNING
!
Do not input voltage over 1000Vrms. It is possible to measure higher
voltage. However, it may cause damage to the meter. Be cautious to
avoid electric shock when measuring high voltage.
1. Switch the function dial to Vposition (range: 6V/60V/600V/1000V).
2. Connect the common test lead to COM terminal, then insert the red test lead into the to
Hz
V Ω°C
terminal.
3. Connect the leads to the correct test points in the circuit to measure voltage.
NOTE:
•Before using the device, it is suggested to measure a known voltage for verication.
•The meter input impedance is about 10MΩ. This load may cause measurement error when
measuring the high impedance circuit. In most cases, if the circuit impedance is under
10kΩ, the error can be ignored (<:0.1%).
•The input impedance of DC mV scale is innite ( > 1000MΩ), and it does not attenuate
when measuring weak signals, so the measurement accuracy is high. However, when the
test leads are disconnected, there may be a value on the screen, which is normal and will
not aect the measurement result.
•Readings of AC measurement are true RMS.
•At AC voltage position, short press {<2s) SEL/REL button to enter frequency measurement.
Frequency measurement range: 45Hz-1kHz (for reference). Min measurement amplitude:
10% of voltage range.

RESISTANCE MEASUREMENT
WARNING
!
• To avoid damaging the meter or to the device under test, disconnect
circuit power and discharge all the high-voltage capacitors before
measuring resistance.
• To avoid electric shock, do not input higher than DC 60V or AC 30V
voltages.
1. Switch the function selector to Ωposition (range: 600Ω/6kΩ/60kΩ/600MΩ/60MΩ), make
sure the circuit power is turned o.
2. Connect the common test lead to COM terminal then insert the red test lead to Hz
V Ω°C
terminal.
3. Connect the leads to the correct test points in the circuit to measure voltage.
NOTE:
•If the measured resistor is open or the resistance exceeds the maximum range, the “OL”
symbol will be displayed on the screen.
•When measuring low resistance, the test leads will produce 0.1Ω-0.3Ω measurement error. To
obtain accurate measurement, short-circuit the test leads and use the REL function.
•If the resistance is greater than 0.5Ω when the test leads are shorted, please check if the test
leads are loose or damaged.
•When measuring high resistance at 60MΩ range, it takes a few seconds to stabilise the
readings.
•The internal 600mA and 20A fuses can be checked by the 6MΩ measurement function.
Please refer to Picture 5b for more details: Insert the red probe to the 630mA or 20A input
terminal to measure the resistance. If both fuses are blown, the“OL”symbol will appear on
the screen.

CONTINUITY MEASUREMENT
WARNING
!
• To avoid damaging the meter or to the device when testing, disconnect
circuit power and discharge all the high-voltage capacitors before
testing for continuity.
• To avoid electric shock, do not input higher than DC 60V or AC 30V
1. Switch the function dial to the position, and make sure the circuit power is turned
o.
2. Connect common test lead to COM terminal, then insert the red test lead to Hz
V Ω°C
terminal.
3. Connect the probes to the circuit test points.
4. Measured resistance >30Ω : The circuit is broken; buzzer makes no sound;
red indicator is on.
Measured resistance, <30Ω: The circuit is in good conduction status; buzzer beeps
continuously; green indicator is on.
If “OL“ appears on the screen, the circuit is in open status.

17OPERATING MANUAL
CAPACITANCE MEASUREMENT
WARNING
!
Please fully discharge all capacitors before measuring (especially
for capacitors with high voltage) to avoid damage to the meter
and personal injury.
1. Switch the function dial to 100mF position, the green indicator should be on.
2. Connect the common test lead to COM terminal, then insert red test lead to Hz
V Ω°C
terminal.
3. Connect the probes to the pins of capacitor.
4. When measuring large volume capacitor, if the yellow indicator is on, it indicates that the
capacitor is being charged, and the green indicator will be on when the capacitor is fully
charged, then wait for the steady reading.
NOTE:
•If the measured capacitor is short-circuited or the capacitance exceeds the maximum
range, the“OL”symbol will appear on the screen.
•When measuring large volume capacitors, it may take a few seconds to obtain steady
readings.
•When there is no input, the meter displays a xed value (intrinsic capacitance).
•For small capacitance measurement, this xed value must be subtracted from the
measured value to ensure measurement accuracy. Or users can choose the relative
measurement function (REL) to automatically subtract the intrinsic capacitance.
