60 C.A 6681 Cable Locater
3.3.3 SEARCH FOR A SHORT-CIRCUIT
Preconditions:
•
The circuit must be dead.
•
Connect the transmitter as shown in figure 20.
•
The measurement method is identical to that used in
§3.1 Getting started
Fig.20
Remarks:
•
During searches for short-circuits in sheathed wires and cables, the depths of
detection vary because the sheathed wires are twisted together in the sheath.
Experience has shown that only short-circuits having an impedance less than
20ohms can be detected correctly. The impedance of the short-circuit can be
measured with a multimeter.
•
During the detection process along the circuit, if the signals received are
suddenly attenuated, the position detected is where the short-circuit is
located.
•
If the impedance of the short-circuit is greater than 20ohms, try using the
method of searching for a break in a circuit (§3.2.2 Locating breaks in lines)
to find the court-circuit.
