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 always assigned to two of the values in manual operation.
As a fourth value there is the internal resistance R, for which the resistance mode (R mode) has to be activated
first, for instance in the quick menu. Refer to
“3.4.3. Configuration via the menu“
Set values can be entered manually in two ways: via
rotary knob
or
direct input
. While the rotary knobs adjust
values continuously, entering them via numeric pad can be used to change values in bigger steps.
Changing a value is immediately submitted, no matter if the DC output is switched on or off.
When adjusting set values, upper or lower limits may come into effect. See section
justment limits“. Once a limit is reached, the display will show a note like “Limit: U-max” etc. for
1.5 seconds next to the adjusted value.

How to adjust set values U, I, P or R with the rotary knobs
1.
First check if the value you want to change is already assigned to one of
the rotary knobs. The main screen displays the assignment as depicted in
the figure to the right.
2.
If, as shown in the example, the assignment is voltage (U, left) and power
(P, right), and it’s required to set the current, then the assignments can be
changed by tapping this touch area. A set of selection fields then appears.
3.
After successful selection, the desired value can be set within the defined limits.
Selecting a digit is done by
pushing the rotary knob which shifts the cursor from right to left (selected digit will be underlined):
►How to adjust values via direct input:
1.
In the main screen, depending on the rotary knob assignment, values
can be set for voltage (U), current (I), power (P) or resistance (R) via
direct input by tapping on the set/actual value display areas, e.g in the
uppermost area of voltage.
2.
Enter the required value using the ten-key pad. Similar to a pocket
calculator the key
clears the input.
Decimal values are set by tapping the point key. For example, 54.3 V
is entered with
and
.
3.
The display then switches back to the main page and the set values
take effect.
When entering a value which would exceed the upper/lower adjustment limit it would be rejected
with an appropriate message.
