Step 7. Program calibration dates
Use the following command to set the calibration adjustment date:
smua.cal.adjustdate = os.time{year=2019, month=12, day=1}
Optionally, it is possible to set the calibration date and calibration due date with the following
commands:
smua.cal.date = os.time{year=2019, month=12, day=1}
smua.cal.due = os.time{year=2020, month=12, day=1}
If you do not wish to set a calibration date or calibration due date and want to clear the previous
values, use the following commands:
smua.cal.date = 0
smua.cal.due = 0
The actual year, month, day, and (optional) hour and minute should be used (seconds can be given
but are essentially ignored due to the precision of the internal date storage format). The allowable
range for the year is from 1970 to 2037, the month is from 1 to 12, and the day is from 1 to 31.
Step 8. Save calibration constants
Calibration adjustment is now complete, so you can store the calibration constants in nonvolatile
memory by sending the following command:
smua.cal.save()
Unless you send the save command, the calibration adjustment you just performed is temporary.
Step 9. Lock out calibration adjustment
To lock out further calibration adjustment, send the following command after completing the
adjustment procedure:
smua.cal.lock()
Reinstall the 2601B-P-INT
When the calibration and adjustment procedures are complete, reinstall the 2601B-P-INT.
Refer to Installing the 2601B-P-INT (on page 2-6) for detail.
