Series 2600 System SourceMeters Reference Manual Calibration 16-21
Return to Section 16 topics 2600S-901-01 Rev. A / May 2006
Step 5. Program calibration dates
Use the following commands to set the calibration date and calibration due date:
smua.cal.date = os.time({year=2005, month=1, day=1})
smua.cal.due = os.time({year=2006, month=1, day=1})
The actual year, month, day, and optionally hour, and minute should be used
(seconds can be given but will essentially be ignored due to the precision of the
internal date storage format). The allowable range for the year is from 2005 to
2037, the month is from 1 to 12, and the day is from 1 to 31.
Step 6. Save calibration constants
Calibration is now complete, so you can store the calibration constants in non-
volatile memory by sending the following command:
smua.cal.save()
Calibration just performed will be temporary unless you send the save command.
Step 7. Lock out calibration
To lock out further calibration, send the following command after completing the
calibration procedure:
smua.cal.lock()
Step 8. Repeat calibration procedure for Model 2602/2612 Channel B
For the Models 2602 and 2612 only, repeat the entire procedure above for
Channel B. Be sure to:
• Make test connections to Channel B terminals.
• Substitute “smub” for “smua” in all commands.
