Current measurement values (Display)
In normal mode, pushing the button Display switches between five different overview screens.
Main display
The main display shows current measure and set values. The display is divided in two separate displays. After enabling
the unit, the measured values for output voltage and putput current (position 1 and 2) are displayed. On the right
display (position 6) the actual set value (Preset V
set
) is shown. To change this value, the rotary pulse encoder Display
must be turned. Pushing the button Select , toggles through the next set parameters (in UI mode it will be output
current). To open the mode select menu (left display, position 3) where different operation modes are available, the
button Select must be pushed again.
