8.2.4. Diodes and Continuity Measurement
8.2.4.1. Diode test
• Turn the function/range SELECT switch “Ω
” gear. Press the SELECT key to choose the desired
diode measurement mode.
• Insert the red test probe and black test probe into the respected “VΩ” and “COM” ends.
• Connect the red test probe to the positive of the diode and the black test probe to the negative.
• Read the currently measured result from the display.
Note
• In case of open diode or reverse polarity, the display will show “OL”.
• When the online diode is measured, be sure to shut off the line power supply and discharge all
capacitors completely.
• After the measurement is over, immediately disconnect the test probe and the tested circuit.
8.2.4.2. Continuity test
• Turn the function/range SELECT switch “Ω
” gear.
• Press the SELECT key to choose the desired continuity measurement function.
• Insert the red test probe and black test probe into the respected “V” and “COM” ends.
• Simultaneously connect the test probes to both ends of the tested circuit as shown.
• If the resistance between both ends of the circuit is less than about 50Ω, the built-in buzzer will sound.
