Step Procedure
1 Turn power control to „0“ (0 left limit stop).
2 Set impedance selector switch to Zi = 0.3 W.
3 Select max. output power with button „60VA“ or
„600VA“.
4 Select output frequency with button „2kHz“ or
„10kHz“.
5 Switch on unit by pressing button „ON“.
TG600 is ready for operation.
Impulse operation
By switching, the TG600 unit can be operated at 2kHz
and at 10kHz. As a result, the detecting signal can be
distinguished from the interfering signal easier.
Do not apply with twist method.
Operation with reduced power
For most fault location methods (e.g. twist method) a
highest possible current in the cable is advantageous.
When tracing cables (route determination) and
especially for cable selection, current induction from
adjacent lines must be avoided.
In such cases, an output power of approx. 1VA to max.
100VA is sufficient.

At an output current I

>30A the output power is switched automatically to 60VA. In this
case, turn back power control and switch back again to max. output power 600VA.
