Diode detection
To avoid electric shock, the diodes carrying voltage must not be tested.
1. Insert the banana plug on the black test lead wire into the negative "COM" socket; the banana plug on the red test
lead wire into the positive "VΩCap" socket.
2. Rotate the knob to select the " " measurement function, the word "RESISTANCE" will appear at the top of
the screen, indicating that it is already in the resistance measurement function.
3. Press the F3 key (SEL) to select the diode detection function. The word "DIODE" will appear at the top of the
screen, indicating that it is in the diode measurement function.
4. Connect the test leads across the diode or semiconductor PN junction under test. (Silicon tube is about 0.5-0.7V,
germanium tube is about 0.15-0.25V).
