Area for assigning the rotary knobs
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.
The area will then show the assignment:
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 knobs, unless the assignment is changed. Alternatively to tapping on the knob depiction, the assign-
ment can also be changed by tapping the coloured set value areas. However, values can be entered directly with a
ten-key pad by tapping on the small icon
.
This method of entering values allows for big set value steps.

The rotary knobs also have a pushbutton function which is used in all value adjustment to move the cursor by
rotation as shown:
