MRX(G) Marker locator is capable of locating cable to ground faults caused by damaged cable sheaths and can also be used to locate damage to insulation on pipelines. This process is known as Fault-Finding and uses specific fault find signals applied to the target.

Fault find signals can only be applied using Direct Connection method.

The A-frame accessory is used to locate cable sheath faults on power and telecom cables or insulation faults on pipelines.

To use Fault-Find you will need the following equipment:

• MRX(G) Marker locator
• Tx-5 or Tx-10 transmitter
• Accessory A-frame with connecting lead
• Direct connection lead and earth stake

There are 2 types of signals that can be used for fault finding:

• 8K Fault Find – useful for sheath faults on cables but can also be used on pipelines over shorter distances.
• CD Fault Find (only available on Tx-10) – this low frequency signal is very useful on pipelines and particularly useful on long distance pipelines. CD can also be used for locating sheath faults on cables.
