questionableRegister
The status of the questionable status calibration summary register; a zero
(0) indicates no bits set (also send 0 to clear all bits); the only valid value
other than zero (0) is 2
Details
These attributes are used to read or write to the questionable status calibration summary registers. Reading a
status register returns a value. The binary equivalent of the returned value indicates which register bits are set.
The least significant bit of the binary number is bit B0, and the most significant bit is bit B15.
For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to
(on
Enable and transition registers
(on page E-19). The individual bits of this register are defined in
the following table.
Bit Value
Description
B0
Not used
Not applicable.
B1
status.questionable.calibration.SMUA
Set bit indicates that the calibration constants
stored in nonvolatile memory were corrupted and
could not be loaded when the instrument powered
up.
Bit B1 decimal value: 2
Binary value: 0000 0010
B2 to
B15
Not used
Not applicable.
In addition to the above constant,
questionableRegister
can be set to the decimal equivalent of the bit to
set.
Example
status.questionable.calibration.enable =
status.questionable.calibration.SMUA
Uses a constant to set the SMUA bit
of the questionable status calibration
summary enable register.
