Method of Measurement
AC /DC Voltage and Resistance Measurement
1. Press the power key to turn on the meter
。
2. The probe is parallel to the circuit to be tested ACV, DCV or
resistance. Instrument automatic identification of AC voltage, DC
voltage or resistance.
3. When measured resistance, resistance is less than about 50,
built-in buzzer alarm.
4. Read measured results from the display, while measuring DC
voltage, it will show the voltage polarity of tested point of red and
black test lead at the same time.
5. When finished measurement, press the power key and hold for 2
seconds to turn off the instrument.
Warning
To prevent possible electric shock, fire or personal injury, before
measuring the resistance, please disconnect the power supply of
the circuit under test firstly, and fully discharge all the high voltage
capacitors.
After completed with all the measurement operations, make sure
to disconnect the probe and the circuit under test.
Non-contact Voltage Detection
1. Turn on power
2. Press and hold the "NCV" button, and then place the item under
test near the instrument non-contact voltage sensing area (less
than 5mm) to sense AC voltage.
3. Non-contact voltage indicator light will light up, saying there is AC
voltage present.
