5.4 SCPI Command Description
5.4.1 SCPI Condition Register
You can obtain the state of the power supply and read parameters from the operation register. The different states
of the power supply can be read from 7 condition registers. These registers are status byte register, standard event
register, quest condition register and operation status register. The status byte register stores the information of 3
other registers. The following table provides the details on each register’s meaning.

Operation status
sub register
0 CAL The power supply is calculating new calibration parameters.
1 UNR The status of the power supply is unregulated.
2 CV The power supply is in constant voltage condition.
3 CC The power supply is in constant current condition.
4 RI Not used
Quest condition
