3.2.1 Measurement of AC and DC voltage
To avoid electric shock and/or damage to the unit do not measure over 600 V.
The voltage ranges for AC and DC (AC/DC) of the device are: 999.9 mV, 9.999 V, 99.99 V and 600 V.
Measure the AC or DC voltage:
1. Turn the rotary switch to the icon (press the SEL button to switch between DC and AC voltage).
2. Connect the black and red test plug of the COM input socket and the V input socket.
3.2.2 Resistance / capacitance measurement
To avoid damage to the device or the equipment being measured, all powered circuits should be cut off and all high voltage capacitors
should be completely discharged before resistance measurement.
Measure the resistance:
1. Turn the rotary switch to position
, to switch to resistance measurement mode;
2. Connect the black test plug and the red test plug to the COM input socket and the V / Ω.
3.2.3 On/Off diode measurement
The device adopts the function of automatic diode on/off recognition.
Perform on/off or diode measurement:
1. Turn the rotary switch to the position
/ .
2. Connect the black test plug and the red test plug to the COM input socket and the V / Ω.
3.2 4. Capacitance measurement
To avoid damage to the instrument, all powered circuits should be cut off and all high voltage capacitors should be completely di-
scharged before the capacity measurement. Use DC voltage to confirm discharge of the capacitor.
1. Turn the rotary switch to the position
and press the SEL button to enter capacity measurement mode.
2. Connect the black test plug and the red test plug to the COM and input sockets .
3.2 5. Current measurement
When the voltage in the circuit exceeds 250 V, do not measure the current in the circuit.
1. Set the rotary switch to mA/A to measure the current.
2. Connect the black test plug to the COM input socket. If the measured current is less than 600mA, plug the red test plug into
the uA/mA input socket; if the measured current is between 600mA and 10A, plug the red test plug into the 10A input socket.
Note: The SEL switching button can be used to carry out the AC/DC conversion.
3.2 6. NCV test
Press the NCV key and close the top of the instrument to the wire, the corresponding signal strength indicator lights up when induced
low voltage,
--- L
is displayed on the screen, and the green indicator lights up when induced high voltage,
--- H
is displayed on the
screen, and two red indicators light up. The buzzer sounds an alarm at a different frequency.
3.2 7. Testing the live wire
1. Turn the rotary switch to the voltage position.
2. Connect the red test plug to the V input socket.
3. Close the black plug to the live wire. If a current flow is detected, the screen displays LIVE, the red indicator is on and the
buzzer sounds an alarm.
3.2 8. Battery or rechargeable battery test
1. Turn the knob to the battery symbol.
2. Connect the red test plug to the V input socket and the black plug to the COM port.
3.2 9. SMART measurement
1. Set the rotary switch to the SMART position, in this case the instrument will go into smart measurement mode.
2. Connect the black test plug and the red test plug to the COM input socket and the V/Ⅲinput socket.
3. The device will automatically evaluate the measured value and the type of signal measured.
Note: SMART can automatically recognize AC voltage, DC voltage, resistance
