smua.cal.due
This attribute stores the calibration due date for the next calibration.
Usage
calDue = smua.cal.due
smua.cal.due = calDue
Due date of next calibration (0 indicates that no date is set)
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 smua.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 reflects the due date stored with that set.
smua.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, smua.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 calibration due date equal to one year
from the present time set on the instrument.
