3.4.6
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 in
-
stance in the quick menu. Refer to
“3.4.3. Configuration via the menu“
“3.2.4. Internal resistance regulation“ for details.
Set values can be entered manually in two ways: via
rotary knob
or
direct input
. While the rotary knobs adjust values con-
tinuously, 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 “3.4.4. Adjustment
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.
S
electing 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.
3.
Decimal values are set by tapping the point key. For example, 54.3 V is entered
with
and
.
4.
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.
