5-2 Audible continuity test
On the 400 W , measurement, a continuous beep is emitted for a
resistance R < 40 W . Response time: 100 m. secs.
Protection: same as resistances
Never do a diode test on a live circuit.
Plug the leads into the multimeter and connect to the terminals
of the component to be tested.
Put the switch in the
- in the direct direction, the display gives the value of the junction in
volts (1 mV resolution)
- accuracy: ± 1,5 % L ± 10 ct
- live circuit voltage: < 3 V...
- short circuit current: 0.8 mA
- in the reverse direction, the display indicates the voltage of the live
circuit, in the region of 4 V.
Save the value, if necessary by pressing on the HOLD button
With this function, apart from testing classic diodes, it is also possible
to test electroluminescent diodes (LED's or any other semi-conductor
whose junction corresponds to a direct voltage of less than 3 V.
