CV = The unit is operating in constant voltage mode.

CC+ = The unit is operating in constant current mode.

UNR = The output of the unit is unregulated.

OV = The overvoltage protection circuit has tripped.

OT = The over-temperature protection circuit has tripped.

OC = The overcurrent protection circuit has tripped.

ERR = A programming error has occurred. Use ERR? to clear.

CC= The unit is operating in negative constant current mode.

INH = The external remote inhibit signal has turned the output off.

FAST = The output is in Fast operating mode. (Agilent 66332A, 6631B, 6632B, 6633B, 6634B only) NORM = The output is in Normal operating mode. (Agilent 66332A, 6631B, 6632B, 6633B, 6634B only)

RQS = The dc source has generated a service request. Use a serial poll to clear. ERR = Same as ERR bit in Status register. Use ERR? to clear.

RDY = This bit cleared when unit busy processing commands. Set when processing complete. PON = A Power-on has occurred. Use CLR to clear.

FAU = A bit has been set in the Fault register. Use FAULT? to clear.
