Save calibration and set the adjustment dates
Calibration is temporary unless you send the
cal.save()
command. Also, calibration data is not
saved if calibration is locked, if invalid data exists, or if all steps were not completed.
Use the following commands to save and lock calibration adjustments.
cal.save()
cal.lock()
reset()
Calibrations are complete after they have been saved and locked.
Example TSP calibration code
The following code examples include code for the calibration steps and code that displays prompts on
the Model DMM7510 front panel.
You may need to adjust the calibration commands in this code for your equipment setup.
