5.3 Continuity Test with Constant Current of 1 mA
Ð Disconnect supply power from the electrical circuit of the de-
vice to be measured, and discharge all high-voltage capaci-
tors.
Ð Make sure that the device under test is voltage-free.
Interference voltages distort measurement results!
Ð Set the rotary switch to .
Ð Connect the conductor path under test as shown.
“0 L” appears at the display in the case of an open connection.
Open circuit voltage is approximately 3 V.
Limit Value for Volume Resistance
Depending upon the selected limit value, 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 limit value. The limit
value can be adjusted in the “SET” menu (see also
section 6.4):
