Supervisory Commands
The commands below enable the remote configuration of the supervision features (Events)
of the unit, related to voltage, current or power on the DC Input.

Identical to event OPD, as

The :ACTion can have following parameters:
NONE =
Event inactive, no supervision
SIGNAL =
As soon as the event occurs, a status text is presented in the status field
of the unit’s display resp. a bit in the Questionable Register (STAT:QUES?)
is set (see Status registers). The bit indicates that a specific event has
occurred. This can be used to record the event.
WARNING = As soon as the event occurs, a warning pop-up is presented in the unit’s
display resp. a bit in the Questionable Register (STAT:QUES?) is set (see
Status registers). The bit indicates that a specific event has occurred. This
can be used to record the event.
ALARM =
As soon as the event occurs, a warning pop-up is presented in the unit’s
display, as well as an acoustic alarm is initiated and the DC input/output is
switched off resp. a bit in the Questionable Register (STAT:QUES?) is set
(see Status registers). The bit indicates that a specific event has occurred.
This can be used to record the event.
Note: The action ALARM lets the unit act similar to when a unit alarms occur. However,
unit alarms still have priority. This means that if, for example, the values OVP and
OVD would be equal and the output voltage reaches that level, the unit would
initiate an OV alarm rather than an OVD event.

Adjustment Limit Commands
Adjustment limits are additional, globally effective, adjustable limits for the set values U, I, P
and R (where featured). The purpose is to narrow the standard 0...100% adjustment range
and to prevent, for example, to accidently set a too high voltage for the load. There is also
the overvoltage protection (OVP), but it is generally better to block irregular set values in
the first place.
In case a set value is sent to the unit that would exceed an adjustment limit, no matter if too
high or too low, the unit will ignore it and put an error into the error queue. At the same
