3-5 Continuity Check by Internal Sounder
1. Connect the red test lead to the VΩHz terminal and the other (black) test lead to the COM terminal.
2. Set the rotary function selector to Ω : position.
3. Connect the test leads to the circuit to be measured. The internal sounder will operate if the resistance of the
circuit measured is lower than 30Ω approximately.
3-6 Diode Check
1. Set the rotary switch at Ω : position.
2. Connect black test lead to COM terminal and red lead to VΩ Hz input terminal.
3. Connect test leads to the diode. Normally the forward voltage drop of good silicon diode is shown between
0.400V and 0.900V. If the diode under test is defective. 0.000 (short circuit) or OL (non-conductance) is
displayed. During reverse check of a diode, the diode under test is defective if 0.000 or other values are
displayed.
