” Loop Impedance Measurement with 2 mA Constant Current
Ð Disconnect supply power from the electrical circuit of the
device to be measured, and discharge all high-voltage
capacitors.
Ð Make sure that the device under test is voltage-free.
Interference voltages distort measurement results!
Ð Set the rotary switch to R
SL
.
RSL appears at the display.
Ð Connect the measuring point under test as shown.
Depending upon the selected limit value / threshold, the
multimeter generates a continuous acoustic signal if the
respective value is exceeded.
“0L” appears at the display in the case of an open connection.
The limit value can be adjusted in the “SETUP” menu (see also
chapter 6.4):
