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.
bit code 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
register
0 OV Not used
1 OT Over temperature
Standard event
register
0 OPC Operation of power supply is completed.
2 QYE Query error. Data of output array is missing.
3 DDE Device-dependent error. Data stored in register is missing or error occurs
in preliminary checkout.
4 EXE Execution error. Command parameter overflows or the condition is not
right.
5 CME Command error. Syntax or semantic error occurs when receiving
information.
7 PON Power on. It is 1 when power supply is reset.

5 ESB If a standard event status enable register changes, ESB is 1.
6 MSS
7 OPER If a operation event enable register changes, OPER is 1.
