Return Parameters : Always Zero
STATus : QUEStionable : CONDition?
Description : This query returns the value of the Questionable Condition
register, which is a read-only register that holds the real-time
questionable status of the AC source.
Query Syntax : STATus : QUEStionable : CONDition?
Parameters : NONE
Return Parameters : <NR1>, valid range: 0 ~ 511
STATus : QUEStionable [: EVENt] ?
Description : This query returns the value of the Questionable Event register.

STATus : QUEStionable : NTRansition
Description :
These commands make the values of the Questionable NTR
register set or read.
These registers serve as polarity filters between the Questionable Enable and
Questionable Event registers, and result in the following actions:
* When a bit of the Questionable NTR register is set at 1, a 1-to-0 transition
of the corresponding bit in the Questionable Condition register will cause
that bit in the Questionable Event register to be set.
* When a bit of the Questionable PTR register is set at 1, a 0-to-1 transition
of the corresponding bit in the Questionable Condition register will cause
that bit in the Questionable Event register to be set.
