Saving calibration constants using SCPI commands
You can save the calibration constants to internal memory after each calibration procedure by
sending:
:CALibration:PROTected:SAVE
However, it works differently when sending this command after each step in a procedure. See the
following table.
Calibration step
What is saved to internal memory:
Step 1
Nothing is saved.
Step 2 and step 3
Only voltage calibration constants are saved.
Step 4 and step 7
The following calibration constants are saved:
 Voltage calibration constants
 Current calibration constants for the 10 mA and 100 mA ranges
Step 8
Saves all of the calibration constants.
You can also cancel the calibration and eliminate the new constants by sending:
:CALibration:PROTected:CANCel
When you save the constants, you need to configure the calibration date. For details, see Configure
the calibration date (on page C-23).
Configure the calibration date
You can configure the calibration date before saving the calibration constants. You can also configure
it after saving.
To configure the date, send the following command:
:CALibration:PROTected:DATE <year>,<month>,<day>
If you do not configure the date for calibration, the instrument uses the last calibration date.
