EXTERNAL VIEW

• 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.
The output is factory set to 0 %.
