As an example, to set bit B8 of the questionable status SMU A summary enable register, set
status.questionable.instrument.smua.enable =
status.questionable.instrument.smua.CAL.
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 B8 and B9, set questionableRegister to 768 (which is the sum of 256 + 512).
