3.3.5 Display modes for actual and set values
In general, the display of a PS 9000 model shows the actual output voltage and the related set value in the left
half of the display and the actual output current and related set value in the right half. In order to have the power
set value in direct access, the display mode can be switched.
Mode UI
Only voltage (U) and current (I) are displayed. This is the default mode.
The set values is here only accessible in the setup menu or quick menu.
Mode UI(P)
Additionally to the actual and set values of Strom (I) and voltage (U)
the actual power (P) is displayed.
Mode UP(I)
Similar to mode UI(P), but with the power set value displayed instead,
which is now assigned to the right-hand rotary knob for adjustment.
The set value of current then becomes accessible in the setup menu
or quick menu.
► How to change the display mode
1. Switch off the DC output and push button to call the setup menu.
2. In the menu navigate to “HMI Setup” and push . Then in the submenu navigate to “Status Page Set-
tings” and push again.
3. Select the desired display mode (see above) with the right-hand rotary knob.
4. Accept the settings with or discard them with .
Depending on your setting, the main display will change after leaving the setup menu and the right-hand rotary
knob is then either assigned to set value of current or power
3.3.6 Manual adjustment of set values
The set values for voltage, current and power are the fundamental operating possibilities of a power supply and
hence the two rotary knobs on the front of the device are usually assigned two of the three values in manual op-
eration. Default assignment is voltage and current.
The set values can only be adjusted with the rotary knobs.
Entering a value changes it at any time, no matter if the output is switched on or off.
When adjusting the set values, upper or lower limits may come into effect. See section „3.3.4.
Adjustment limits“. Once a limit is reached, the display will show a note like “Limit: U-max” etc.
or “[i]” for 1.5 seconds.
► How to adjust values U, I or P with the rotary knobs
1. First check whether the value to be changed is assigned to one of the rotary knobs. The assignment can
be changed in the setup menu by selecting a different display mode. See „3.3.5. Display modes for actual
and set values“.
2. With mode UI selected and as long as the main display is active, turn the left-hand knob to adjust output
voltage and the right-hand knob to adjust the output current. In mode UP(I), turn the right-hand knob to
adjust the output power.
3. Any set values can be adjusted with the adjustment limits. For switching the digit to adjust, push the rotary
knob that you are currently using to adjust the value. Every push moves the cursor under the digit in clock-
wise order:
