How to avoid picking up radiated noise on the remote sense wires

The remote sense leads carry very little current, so light gauge wires can be used.

However, steps should be taken to ensure that the remote sense wires do not pick up radiated noise – this can be achieved by:

1. twisting the +ve and -ve sense wires together
2. shielding the wires from the noise

TIP: It is best to use different coloured sense wires (e.g., black and red) so that after they are twisted it is easy to determine which wire is the +ve and -ve sense.
