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. 
What is saved to internal memory: 
Only voltage calibration constants are saved. 
The following calibration constants are saved: 
  Voltage calibration constants 
  Current calibration constants for the 10 mA and 100 mA ranges 
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.
