TOMKAT & SIGEN Function Check

It is recommended that the operation of the TOMKAT Cable Avoidance Tool and SIGEN Signal Generator are checked before use.These checks DO NOT guarantee full system performance. The Cable Avoidance Tool and Signal Generator should be returned to the manufacturer or an approved agent for recalibration every 12 months.

Power Mode

Select Power Mode.
Set Sensitivity fully clockwise and point the body of the TOMKAT Cable Avoidance Tool at a fluorescent light from a distance of  approximately 1m. With the light switched on a tone should now be heard. Reducing the sensitivity should cause the TOMKAT to cut out.

Radio Mode

Select Radio Mode. Set the Sensitivity fully clockwise and, from a distance of less than 0.25m, point the unit at a metal conductor of length greater than 100m (for example a pipe or cable). A warbling tone should be heard.

Generator Mode

Locate an outdoor test area that is free from extraneous fields resulting from overhead and underground cables. The area should also not be near fences, steel framed buildings, or on reinforced concrete as the signal will be reduced.Place the SIGEN on the ground and switch to induction. Ensure there is a sound from the speaker. Hold the TOMKAT approximately 10m away with the foot facing towards the SIGEN. Select G mode and ensure sensitivity is at maximum and depress the trigger. Check there is an audio response from the TOMKAT.
