The actual values of current and power can be negative (signed) or positive (unsigned). A negative value belongs to sink
mode and indicates that the device is working as electronic load.
When the DC terminal is switched on the actual regulation mode is displayed as
CV, CC, CP
or
CR
,
next to the corresponding
actual value, as shown in the figure above.
The set values can be adjusted with the rotary knobs next to the display screen or can be entered directly via the touchscreen.
When adjusting with the knobs, pushing the knob will select the digit to be changed. Logically, the values are increased by
clockwise turning and decreased by anti-clockwise turning.

Area for assigning the rotary knobs and DC terminal status
The two rotary knobs next to the display screen can be assigned to various functions. This area shows the actual assign-
ments. These can be changed by tapping this area, as long as the panel is not locked.
The physical quantities on the depiction of the knob show the current assignment. The
left knob is always assigned to the voltage (U), while the right knob can be switched
by tapping on the depiction. Furthermore, the DC terminal status is indicated by two
LEDs (green = on).
There are following possible rotary know assignments:
