Questionable Status Registers
This register set feeds to bit B3 (QSB) of the Status Byte. The bits used in the Questionable Status
Register set are described as follows:
•
Bit B8, Calibration (CAL):
Set bit indicates that calibration is questionable.
•
Bit B9, Unstable Output (UO):
Set bit indicates that an unstable output condition was detected.
•
Bit B12, Over Temperature (OTEMP):
Set bit indicates that an over temperature condition was
detected.
•
Bit B13, Instrument Summary (INST):
Set bit indicates that a bit in the Questionable Status
Instrument Summary Register is set.
For more information on the Questionable Status Register, refer to
page E-1) and the figures in this appendix.
Questionable Status Registers
As shown in the status model's
Operation event, I/O, and TSP-Link registers
(on page E-12), there
are seven register sets associated with Questionable Status. Commands are summarized in the
Status byte and service request (SRQ)
(on page E-15) topic. Note that bits can also be set by using
numeric parameter values. For details, see
Programming enable and transition registers
(on page E-
14).
For example, either of the following commands will set the CAL enable bit (B8):
status.questionable.enable = status.questionable.CAL
status.questionable.enable = 256
When reading a register, a numeric value is returned. The binary equivalent of this value indicates
which bits in the register are set. For details, see
(on page E-15). For example, the
following command will read the Questionable Status Enable Register:
print(status.questionable.enable)
