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
assignments. 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 as-
signment. 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:
U I
U P
U R
Left rotary knob: voltage
Right rotary knob: current
Left rotary knob: voltage
Right rotary knob: power
Left rotary knob: voltage
Right rotary knob: resistance
(only with R mode active)
Due to the device having two set values each for current, power and resistance, tapping multiple times will cycle
through the 4 resp. 6 assignable set values for this knob. The currently not selected set values can’t be adjusted
via the rotary knob, unless the assignment is changed.
