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.

OS = Open sense lead detected (Agilent 66111A, 66311B/D) 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 6632B, 6633B, 6634B only) NORM = The output is in Normal operating mode. (Agilent 6632B, 6633B, 6634B only)
