Usage
questionableRegister = status.questionable.calibration.condition
questionableRegister = status.questionable.calibration.enable
questionableRegister = status.questionable.calibration.event
questionableRegister = status.questionable.calibration.ntr
questionableRegister = status.questionable.calibration.ptr
status.questionable.calibration.enable = questionableRegister
status.questionable.calibration.ntr = questionableRegister
status.questionable.calibration.ptr = questionableRegister
questionableRegister
The questionable status calibration summary register's status. 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 Status register sets
(on page E-
2) and Enable and transition registers
(on page E-18). The individual bits of this register have the following
meanings:
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-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
Sets the SMUA bit of the
questionable status calibration
summary enable register using a
constant.
