3M 965DPS RFL Resistance Fault Locate, Separate Pair This is the preferred hookup

RFL (Resistance Fault Locate)

Use this function to locate a Resistance Fault on a pair or on a single conductor.

There are two possible hookups: Separate Pair or Single Pair. Use [Tab] to switch between the two hookups.

Separate Pair (This is the preferred hookup)

You must first use the Resistance function to determine the faulted conductor and identify a separate good pair (a pair with no faults).

Once you identify the wires, connect the shorting strap at the ‘far-end’ with the common (red) clip to the faulted conductor and the black clips to the two wires of the separate good pair.

Press the [RFL] key and select “Separate Pair” by pressing the [Tab] key.

The hookup screen will show the last selected wire gauge and temperature. Use the [Setup] key to change the gauge, temperature, or to enter a known distance to Strap.

Note: Either the temperature or length (distance to Strap) must be selected as unknown. Enter the pound (#) sign as the unknown.
