RD Accessory A-Frame
The Accessory A-Frame is can be used to find
cable faults to ground in two ways, the CD signal
method and FF signal method.
Transmitter Setup
The only method of Transmitter signal application
that can be used for fault finding is by direct
connection to the defective cable or to the sheath.
Connect the Connection Cable to the Transmitter.
Clip the Red lead to the defective cable or cable
sheath cleaning the area if necessary to ensure
connection is good. Extend the Black lead of the
Connection Cable as far as possible and at 90° to
the probable route of the target cable then clip to a
grounding point such as a Ground Stake. Do not
clip earth lead to water pipe or buried cable which
could carry the signal.
Note: In situations where the target cable route is
erratic or unpredictable, it may be advisable to
carry out a trace and mark the cable route. Then
return and follow the marked route carrying out
FaultFind checks at regular survey intervals.
Switch the Transmitter On.
Using the Transmitter A-V-O key, select the Ohms
mode, '- - -' is displayed. Press and hold the Line
key until the resistance reading is displayed.
If the resistance is higher than 20 kilohms, 'Or'
(Over Range) will be displayed.
