4. The beeper sounds when the resistance of the circuit is less than about 30Ω.
Note
Before measurement, switch off the power of the measured circuit and fully discharge all capacitors.
- Diode test
1. Connect the black probe to "COM" jack and the red probe to "
2. Set the function switch to "
3. Connect the red probe to the positive pole of the diode to be measured and the black probe to the negative pole.
4. Read the approximation of the forward voltage drop of diode indicated on the screen. In case of wrong connection of the probes, "OL" will
appear on the screen.
- Capacitance measurement
1. Connect the black probe to "COM" jack and the red probe to "
2. Set the function switch to "
3. Short the two pins of the capacitor to be measured and fully discharge the capacitor.
4. Connect the probes to the two ends of the capacitor to be measured.
