WARNING:
The safety condition is not to connect Fault locator to the energised
cable, even this equipment does not generate any hazardous voltage
to other circuit.
1. Introduction
The Fault Locator is a pulse-echo cable test set which provides a visual indication of
cable faults such as open circuits, shorts and bad connections up to 3000m (9500 ft.) on
metallic cables. The principle of operation is that a pulse transmitted into a cable is reflected by any
imperfection.
The speed at which the pulse travels down the cable is depend upon the dielectric (insulation) of the cable
and the Fault Locator can be set to suit any type of
cable dielectric.
A list of typical propagation velocity factor
values is given in table A. and a type of cable fault can be determined as section 5. of this manual.
The Fault Locator is available with 120 ohm output impedance and 0.67 defaults PVF
2. Batteries
The unit operate from 6 AA size batteries. Instruction for place / replace batteries are as follows
1) Unscrew the two screws which secure the battery cover on rear side of unit case
2) Lift off the cover
3) Remove old batteries or place new batteries by following polarity mark on the battery pocket
4) Replace battery cover and secure two screws by not over-tightening it
