is made, the backlight returns automatically. Furthermore the brightness can be selected
in 10 steps.
Panel Contrast Here the user can adjust the display contrast to suit best.

3.3.4 Adjustment limits (Limits)
Adjustment limits are only effective in manual operation and only on the set values in the
main display screen!
Defaults are that all set values (U, I, P, R) are adjustable from 0 to
100%..
This may be obstructive in some cases, especially for protection of
applications against overcurrent. Therefore upper and lower limits for
current and voltage can be set which limit the range of the adjustable
set values.
For power and resistance only upper value limits can be set:
► How to congure the adjustment limits
1. Tap the touch area in the main page.
2. Tap the white arrows to select “3. Limits”.
3. In each case a pair of upper and lower limits for U/I or the upper limit for P/R are assigned to the rotary
knobs and can be adjusted. Tap the selection area for another choice .
4. Accept the settings with .
The set values can be entered directly using the ten-key pad. This appears when the touch area
for rotary knob assignment is tapped (bottom center)
The adjustment limits are coupled to the set values. It means, that the upper limit may not be set
lower than the corresponding set value. Example: If you wish to set the limit for the power set
value (P-max) to 6.00 kW while the currently adjusted power set value is 8.00 kW, then the set
value rst would have to be reduced to 6.00 kW or less, in order to set P-max down to 6.00 kW.
