• How to Set an Output

Turn the Display Selector (C) to the top position.

The Setpoint Display (B) shows the current setpoint (-10.0 –

+105 %). Press UP/DOWN Control (D) until the display

shows a desired set value.

The Polarity Indicator LED (A) is red when the set value is in

positive range, green when in negative range.
