3-4 Continuity Check by Sounder
1. Connect the red test lead to the "V
Ω
 " terminal and the black test lead to the "COM" terminal.
2. Set the rotary function switch to "

; " position.
3. Connect the test leads to the circuit to be measured. The sounder will operate if the resistance of the circuit measured is
lower than 50
Ω .
4. The sounder may operate when the instrument is first switched on in the continuity mode and all the LCD segments are
displayed.
3-5 Diode Check
1. Set the rotary switch to the "

; " position.
2. Connect the black test lead to the "COM" terminal and the red lead to the "V Ω

" input terminal.
3. Connect the test leads to the diode. Normally the forward voltage drop of good silicon diode is between 0.4V to
0.9V. If the diode under test is defective, "000" (short circuit) or "OL" (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 will be displayed.
