PROT = The output has been disabled because it is
coupled to a protection condition that occurred on
another channel.
UNR = The output is unregulated
INH = The output is inhibited by an external signal
CP– = The output is limited by the negative power limit

These commands set and read the value of the Operation NTR
(Negative-Transition) and PTR (Positive-Transition) registers. These
registers serve as polarity filters between the Operation Condition
and Operation Event registers to cause the following actions:
When a bit in the Operation NTR register is set to 1, then a 1-to-0
transition of the corresponding bit in the Operation Condition
register causes that bit in the Operation Event register to be set.
When a bit of the Operation PTR register is set to 1, then a 0-to-1
transition of the corresponding bit in the Operation Condition
register causes that bit in the Operation Event register to be set.
If the same bits in both NTR and PTR registers are set to 1, then
any transition of that bit at the Operation Condition register sets
the corresponding bit in the Operation Event register.
If the same bits in both NTR and PTR registers are set to 0, then
no transition of that bit at the Operation Condition register can
set the corresponding bit in the Operation Event register.
This query returns the value of the Questionable Event register. The
Event register is a read-only register, which stores (latches) all
events that are passed by the Questionable NTR and/or PTR filter.
Reading the Questionable Event register clears it. The bit
configuration of the Questionable status registers is as follows:
11 10 9
2048 1024 512
PROT UNR INH
This query returns the value of the Questionable Condition register.
That is a read-only register, which holds the real-time (unlatched)
questionable status of the power system.

OT = The over-temperature protection has tripped
CP+ = The output is limited by the positive power limit
PF = The output is disabled by the power-fail - which may be
caused by a low-line or bownout condition on the AC line
OC = The output is disabled by the over-current protection
OV = The output is disabled by the over-voltage protection
