Status Monitoring
The PCR has two mandatory SCPI standard registers, STATus:OPERation and
STATus:QUEStionable, in addition to the IEEE488.2 standard registers.
Register basics
All SCPI registers have standard event/filter
ENABle, and optionally PTRansition and NTRansition. CONDition and EVENt are read-only
registers working as status indicators, and ENABle, PTRansition and NTRansition are read-
write registers working as event and summary filters.
STATus:OPERation
records events or signals that occur during normal
operation.
For example, to check if the PCR is being regulated in CV state, check the CV bit (bit 8) on
the STATus:OPERation register.
'Check whether the CV bit is set
STATus:QUEStionable
records events or signals that occur during normal
operation.
For example, to check if the PCR is being regulated in CV state, check the CV bit (bit 8) on
the STATus:OPERation register.
'Check whether the CV bit is set
Status Monitoring
STATus:OPERation
is used to record events and notifications that occur during
normal operations.
To check whether CV output is being performed, check the CV bit (bit 8) of the
OPERation:INSTrument:ISUMmary{1|2|3} subregister.

STATus:QUEStionable
is used to record events and notifications that occur during
abnormal operations.
To check whether the overvoltage protection function has been activated, check the OV bit
(bit 0) of the STATus:QUEStionable register.
'Check whether the OV bit is set.
Even if bit 0 is true, you can not tell on which phase the overvoltage protection function has
been activated. To check which phase is operating abnormally, check the
STATus:QUEStionable:INSTrument subregister.
'Check which phase is operating abnormally.
All phases whose corresponding bits are true are operating abnormally. You can determine
how the specified phase is operating abnormally by checking the
STATus:QUEStionable:INStrument:ISUMmary{1|2|3} subregister of the phase.
