Obtaining a reference reading
It is useful to obtain a reference reading from the ground stake.
This will provide you with two pieces of information:
! Severity of fault
! Survey interval.
Before taking the reference reading set up the transmitter and receiver as follows:
Setting FF on the transmitter (RD4000T3F)
• Switch the transmitter on by pressing the on/off key
• Press the frequency key repeatedly until the FF LED is illuminated.
Setting FF on the Transmitter (RD4000T10)
• Switch the transmitter on by pressing the on/off key
• Press the on/off key again to select menu
• Press the up arrow or down arrow to select ‘FAULTFIND’ mode
• Press the on/off key again to confirm selection. The FaultFind screen is displayed indicating that the
FaultFind signal is being applied to the cable
• Press the up arrow to select 100% (boost). Press the down arrow to select 50% (normal). Use boost only if
the fault is high resistance or if the cable to be surveyed is long. Using boost in other circumstances will
reduce battery life.
