9. Accessories & Options
9.1 A-frame
The A-frame accessory is used to detect ground faults on pipes and cables. In the case
of pipes, the faults consist of coating defects. In the case of cables, faults are usually
caused by insulation damage allowing the metallic sheath (or internal conductor) to
become in contact with the ground.
9.2 Remote Antenna
The remote antenna can be used to help identify a particular cable on a cable tray or
where cables are bunched together.
9.3 Loc3-10Tx Vehicle Power Lead
12V DC, 30ft (10m) lead to power the transmitter from a vehicle.
If it is intended to apply the transmitter to a target line at high output levels and long
periods, it may be useful to power the transmitter using the 12V DC vehicle power lead.
To power the transmitter from the 12V DC vehicle power lead, connect the lead to the
12V DC input positioned on the side of the transmitter. Plug the cigarette lighter plug
into the vehicle cigarette lighter socket (be sure that the socket is live. Some vehicles
only activate the cigarette lighter when the vehicle is running).
It is not necessary to disconnect or remove the standard batteries as the unit will
automatically select the external 12V DC supply.
9.4 Loc3-10Tx Outdoor Power Supply
23V DC, 30ft (10m) lead to power and charge the transmitter from the mains supply.
9.5 LPC Separation Filter
The LPC separation filter (LPC) is used to safely inject a trace tone to a live cable via
a domestic mains socket, so that the cable can be traced from the premises to the
connection in the street. It is suitable for connecting to voltages between 100V AC and
250V AC.
