Initialisation
Loop:
The R measurement starts automatically.
In this example, the R measurement
shows a resistance of 388 ohms. This is
the resistance for both wires, i.e. the a-wire
(tip) and the b-wire (ring) are short-
circuited (loop). The twisted pair has as
length of 388 ohms/353 ohms/km =
1.1 km, see equivalent circuit diagram.
Laid out one behind the other, the two wire
would have a length of 2.2 km
ARGUS generates a signal tone
for a resistance < 20

>
Deactivate signal tone
Equivalent circuit diagram:
Loop resistance = 2x resistance
ARGUS alway calculates the length of the circuit.
