Details
This attribute stores the calibration due date associated with the active calibration set. The calibration
due date can be read at any time but can only be assigned a new value when calibration has been
enabled with the smu X .cal.unlock() function. It is typically set to the date when the next
calibration should be performed.
This attribute is stored with the active calibration set. If a different calibration set is restored, this
attribute will reflect the due date stored with that set.
smu X .cal.due must be set to the date the next calibration is required using the UTC time and date.
The date is stored as the number of seconds since UTC 12:00 am Jan 1, 1970.
Due to the internal storage format,
smu X .cal.due is only accurate to within a few minutes of the
value set.
Example
smua.cal.due = os.time() + 365 * 24 * 60 * 60
Sets the SMU channel A calibration due date
equal to one year from the current time set on
the instrument.
