4.2 Continuity sound test
On the 400 Ω range a beep sound is given off for a resistance
R ≤ 35 Ω. Temporal response: 100 ms approx.
5. DIODE TEST
Never carry out a diode test on a live circuit
Select the function
Connect the leads to the multimeter and to the terminals
of the component to be tested.
In the forward bias the voltage at the junction is displayed
(1 mV resolution):
- open circuit voltage: typically 3.5 V
- short circuit current: 1 mA,
- in the reverse bias the open circuit voltage is displayed
(in the order of 4 V),
- with no component connected, OL is displayed.
If desired, store the value by pressing the HOLD button.
