ORed into the OPERation summary bit (7) of the Status Byte register. Refer to Status Registers for a
description of each register. The following table describes the bit assignments.
Bit Bit Name Decimal Value Definition
0 CV 1 Output is in constant voltage
1 CC 2 Output is in constant current
2 OFF 4 Output is programmed off
3 not used not used 0 is returned
4 WTG-tran 16 Transient system is waiting or a trigger
5 MEAS-active 32 Measurement system is initiated
6 TRAN-active 64 Transient system is initiated
7-15 not used not used 0 is returned
Questionable Status Group
These register groups record signals that indicate abnormal operation. The group consists of a
Condition, PTR/NTR, Event, and Enable register. The outputs of the Questionable Status group are
logically-ORed into the QUEStionable summary bit (3) of the Status Byte register. Refer to Status
Registers for a description of each register. The following table describes the bit assignments.
Bit Bit Name Decimal
Value
Definition
0 OV 1 Output is disabled by the over-voltage protection
1 OC 2 Output is disabled by the over-current protection
2 PF 4 Output is disabled by an AC power-fail (low-line or brownout)
3 CP+ 8 Output is limited (or disabled) by the positive power limit
4 OT 16 Over-temperature protection has tripped
5 CP– 32 Output is limited by the negative power limit
6 OV– 64 Negative over-voltage protection has tripped
7 LIM+ 128 Output is in positive voltage or current limit
8 LIM– 256 Output is in negative voltage or current limit
9 INH 512 Output is inhibited by an external INHibit signal
10 UNR 1024 Output is unregulated
11 PROT 2048 Output has been disabled because it is coupled to a protection condition that
occurred on another channel
12 OSC 4096 Oscillation detector has tripped
13-15 not used not used 0 is returned
