The clear front panel label shows the current path at each stage through the on-board load resistor. In addition there is a smoothing capacitor which may be switched in as required.
The unit may be powered from a 6V d.c. supply (mains or battery) with the connections reversed for each half cycle. A better approach is to use a slow Signal Generator (about 1Hz) or our special A.C. Waveform Generator which allows the signal to be paused at any point in the cycle.
