appropriate measurement range (there are five ranges from
600mV to 1000V) based on the magnitude of the signal being
measured.Touch the probes to the correct test points of the
circuit to measure the voltage.
3. Make sure to use the test leads to make contact with the correct
testing point on the circuit.
4. Read the voltage value displayed on the screen.

Measure AC Voltage
1. Insert the black test lead into the COM port and the red test lead
into the port.
2. Rotate the knob to the AC voltage range and select the
appropriate measurement range (there are five ranges from
600mV to 750V) based on the magnitude of the signal being
measured.Touch the probes to the correct test points of the
circuit to measure the voltage.
3. Make sure to use the test lead probe to make contact with the
correct testing point on the circuit.
4. Read the voltage value displayed on the screen.
*Do not measure a voltage that exceeds the maximum rated
testing value, as doing so may damage the instrument and
potentially cause harm to yourself.
*When measuring high-voltage circuits, it is necessary to avoid
touching the high-voltage circuits.

10
 Measure AC/DC Current
1. Rotate the knob to the current measurement area, and the current

range indicator light will light up.

2. Select the appropriate measurement range based on the type and

magnitude of the current being measured (with a range of 6000uA to

20A, divided into 5 ranges). Press the SEL button to switch between

AC and DC current measurement.

3. Black test lead should be inserted into the COM port. When measuring

current in the range <600mA, the red test lead should be inserted into

the mAuA port. If the measured current is in the range of 600mA~20A,

the red test lead should be inserted into the 20A port.

4. Disconnect the circuit path to be measured, and insert the meter

probes into the

5. To read the current value displayed on the screen.

* The measured current should not exceed the maximum rated

test value, otherwise there is a risk of damaging the instrument
