Operating the device
6.3 Other control elements
6.3.1 Rotary knobs
Both of the rotary knobs have a push button function. Pushing
any or both of these will effect following:
a) Fine adjustment mode (Fine)
A short push of any of both buttons activates or deactivates the
fine adjustment mode for manual operation. If „Fine“ is active,
all set values, thresholds and limits can be adjusted in smallest
possible steps, no matter what mode is currently active (preset,
memory ect.). It is indicated by the status text „Fine“ in the
status area. Also see section „6.4 Adjusting set values“ below.
b) Device setup
Pushing
both
buttons together for >3s while the output is
off
changes to device setup. It is left the same way.
6.4 Adjusting set values
1. In manual operation
During manual operation, both rotary knobs are used to conti-
nuously adjust the set values of voltage and current from 0%
to 100% nominal value in predefined steps (see table). In order
to set the values for OVP and UVL the button
Preset UVL/OVP
has to pushed once or twice. In order to set the power set value
the button
Preset Power
has to be pushed.
Note
The OVP value can be lower than the voltage set value and
will cause an OV alarm as soon as the output is switched on
and the actual voltage reaches the OVP threshold!
Setting values manually can be done in fine or coarse steps,
whereas coarse is default.
Fine
is required to be activated by
the one of rotary knob pushbuttons and has a step width of 1.
For
coarse
adjustment, following step widths apply in de-
pendency of the nominal values (also refer to technical specs):

Note
The resolution of the set value adjustment in some cases is,
depending on the nominal values, higher than the one of the
output voltage. Thus it can happen that the output voltage
only changes every 2 or 3 steps.
