Signal Generator:

Searching for an Induced Signal

The search pattern used to find the Signal Generator signal
when applied by Induction is slightly different to the search
pattern used on the Power or Radio Modes or with the Signal
Generator on the Direct Connection mode.

1. Move AT LEAST 10 metres away from the Signal Generator
position with your locator. This is to avoid the locator picking
up the airborne signal rather than the signal induced onto the
buried service.

2. Stand so that you are roughly in line with the end of the Signal Generator and hold the locator so that the side of the
locator is facing towards the end of the Signal Generator.

3. Adjust the Sensitivity so that the locator is just showing a visual response and emitting an audible response.

NOTE A Signal Generator will transmit a significant amount of signal into the air as well as into the ground.

NOTE Make sure you keep the locator upright at all times to avoid the risk of picking up the airborne signal.
