Details
These attributes are used to read or write to the questionable status registers. Reading a status
register returns a value. In the binary equivalent, the least significant bit is bit B0, and the most
significant bit is bit B15. For example, if a value of 1.22880e+04 (which is 12,288) is read as the value
of the condition register, the binary equivalent is 0011 0000 0000 0000. This value indicates that bits
B12 and B13 are set.

For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to Status register set
contents (on page E-1) and Enable and transition registers (on page E-19). The individual bits of this
register are defined in the following table.
Bit Value Description
B0-B7
Not used
Not available
B8
status.questionable.CALIBRATION
status.questionable.CAL
An enabled bit in the questionable status
calibration summary event register is set.
Bit B6 decimal value: 256
B9
status.questionable.UNSTABLE_OUTPUT
status.questionable.UO
An enabled bit in the questionable status unstable
output summary event register is set.
Bit B9 decimal value: 512
B10-B11
Not used
Not available
B12
status.questionable.OVER_TEMPERATURE
status.questionable.OTEMP
An enabled bit in the questionable status over
temperature summary event register is set.
Bit B12 decimal value: 4,096
B13
status.questionable.INSTRUMENT_SUMMARY
status.questionable.INST
An enabled bit in the questionable status
instrument summary event register is set.
Bit B13 decimal value: 8,192
B14-B15
Not used
Not available
As an example, to set bit B9 of the questionable status enable register, set
status.questionable.enable = status.questionable.UO.
In addition to the above constants, questionableRegister can be set to the numeric equivalent of
the bit to set. To set more than one bit of the register, set questionableRegister to the sum of
their decimal weights. For example, to set bits B12 and B13, set questionableRegister to 12,288
(which is the sum of 4,096 + 8,192).
