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 the values in manual op-
eration. Default assignment is voltage and current.
As a fourth value there is the resistable internal resistance, for which the resistance mode (R mode) has to be
As a fourth value there is the resistable internal resistance, for which the resistance mode (R mode) has to be
activated in the MENU first. Refer to „3.4.3. Configuration via MENU“ and „3.2.4. Internal resistance regulation“
for details.
Set values can be entered manually in two ways: via
Set values can be entered manually in two ways: via
rotary knob or direct input.
Entering a value changes it at any time, no matter if the DC output is switched on or off.
When adjusting the set values, upper or lower limits may come into effect. See section „3.4.4.
Adjustment limits (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 values with the rotary knobs
1.
First check whether the value to be changed is 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 is required to set the power, 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 clockwise (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
calculator the key
clears the input.
Decimal values are set by tapping the point key. For example, 54.3 V
