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 to 0.900V. If the diode under test is defective, "000" (short circuit) or "OL" (non-conductance) is
displayed. During reverse checking the diode is normal if "1" is displayed, "000" or other values are displayed
if it is defective.
3-7 Hz / RPM Measurement
1. Connect the red test lead to the "VΩ Hz" terminal and the other (black) test lead to the "COM" terminal.
2. Set the rotary function selector to "Hz RPM" position to measure the frequency or RPM.
3. Connect the test leads to the circuit to be measured.
