3-5 Diode Check
1. Set the rotary switch to "
;
" position.
2. Connect the black test lead to the "COM" terminal and the red test lead to "V
Ω
Hz" input terminal.
3. Connect test leads to the diode. Normally the forward voltage drop of a good silicon diode is between
.500V to .900V. If the diode under test is defective, "000" (short circuit) or "1" (non-conductance) is displayed.
Reverse Check of Diode. If the diode under test is good "1" is displayed. If the diode under test is defective
"000" or other values are displayed.
3-6 Continuity Check by Sounder
1. Set the rotary switch to the "
;
" position.
2. Connect the black test lead to the "COM" terminal and the red test lead to "V
Ω
Hz" input terminal.
3. Connect test leads to the circuit under test.
4. Built-in buzzer sounds if the resistance of the circuit under test is below 50
Ω
.
