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 1.04 (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
Enable and transition registers
(on page E-16). 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
status.questionable.HIGHV_NOT_READY
Only 2611B, 2612B, 2614B, 2634B, 2635B,
2636B: Either the interlock is not engaged or
the interlock was engaged recently and the
high voltage supply is still stabilizing. If the
interlock is engaged and this bit is set,
attempting to turn on the output on the
200 V range results in error code 5052,
"Interlock engaged; system stabilizing."
Bit B10 decimal value: 1024
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

As an example, to set bit B9 of the questionable status enable register, set
status.questionable.enable = status.questionable.UO
