DIODE MEASUREMENT
•
Move the rotary dial to the
•
Contact the red probe to the anode of the measured diode, and the black probe to
the cathode of the measured diode.
•
The reading on the screen is the approximate value of the diode forward voltage
drop. If it is connected in reverse, it will display "OL".
Warning
•
Firstly, disconnect the power supply of the circuit and discharge all high voltage
capacitors.
•
If the diode to be tested is an open circuit or with reverse polarity, the instrument
will display "OL".
•
After completing all measurements, always disconnect the probe and the
measured circuit.
CONNECTIVITY TEST
•
Move the rotary dial to the
connectivity function.
•
Contact the probe to both ends of the measured circuit. When the resistance of the
measured circuit is below 50Ω, the buzzer will sound.
Warning
•
Firstly, disconnect the power supply of the circuit to be measured and fully
discharge all high voltage capacitors.
•
After completing all measurements, always disconnect the probe and the
measured circuit.
NON-CONTACT VOLTAGE DETECTION
•
Move the rotary knob of the instrument to NCV.
•
Approach the non-contact voltage induction area of the instrument to the live wire
of the AC voltage (less than 5mm).
•
The non-contact voltage indicating light of the instrument will light up. At the same
time there is a 'beep', which indicates that there is AC voltage on the fire wire.
