8.11 Continuity Test
➭ Disconnect supply power from the electrical circuit of the de-
vice to be measured and discharge all high-voltage capaci-
tors.
➭ Make sure that the device under test is voltage-free. Interfer-
ence voltages distort measurement results!
➭ Set the rotary switch to “ ”.
A loudspeaker symbol appears at the display.
➭ Select the desired threshold with the
scroll keys (see de-
scription below).
➭ Connect the conductor path under test as shown.
➭ Measurement is started immediately.
Adjusting the Threshold
Depending upon the selected threshold, the multimeter generates
a continuous acoustic signal in the case of continuity or short-cir-
cuiting, i.e. at a value of less than the selected threshold.
“OL” appears at the display in the event of an open connection.
The threshold is adjusted with the
scroll keys.
Note
The “Setup for present measurement” submenu cannot
be accessed for the continuity test or the diode test.
8.12 Diode Testing with Constant Current of 1 mA
➭ Disconnect supply power from the electrical circuit of the de-
vice to be measured and discharge all high-voltage capaci-
tors.
➭ Make sure that the device under test is voltage-free. Interfer-
ence voltages distort measurement results!
Refer to section 8.6.4 regarding testing for the absence of
voltage with the help of the direct voltage measurement.
➭ Set the rotary switch to “ ”.
➭ Press the Func key.
The diode symbol appears at the display.
➭ Connect the device under test as shown.
➭ Measurement is started immediately.
Forward Direction and Short-Circuit
The instrument displays forward voltage in volts
(display: 4 places). As long as voltage drop does not exceed the
maximum display value of 4.5 V, several series connected com-
ponents or reference diodes with small reference voltages, as well
as Zener diodes and LEDs, can be tested.
Reverse Direction and Interruption
The measuring instrument indicates overflow “OL”.
Note
Resistors and semiconductor paths connected in parallel
to the diode distort measurement results!
