Setting up

RV1: setting the minimum output voltage.

Set the control voltage to zero (perhaps by disconnecting it). An initial pre-voltage can then be adjusted

using preset RV1. This is especially useful with motors (in order to overcome mechanical resistance) and

with halogen lamps (in order to pre-heat the filament).

 RV2: setting the maximum output voltage.

Set the control voltage to the maximum voltage that you are going to use. The maximum output voltage can

be adjusted with the preset, RV2 (useful for limiting motor speed or light intensity).

 RV3: setting the output frequency.

If an irritating noise can be heard in the load, then it can be resolved by adjusting the output frequency. The

normal position of this preset is the middle of its range.
