A hexagon key is used to clamp the clear Perspex
disc. The yellow line on this disc indicates the
maximum AC and DC voltage available. The
control knob can be turned to adjust the voltage
output from 0 to the preset maximum.
The DC output is higher due to the internal
smoothing capacitor (4700uF).
NOTE: AC and DC outputs are available
simultaneously, but the total current should be
limited to 8 amps.
