Leaving this menu item the analog output will be calibrated based on the
input values (Offset, Span) and will be re-initialized.
The user calibration data are stored in Eeprom when returning to the main
menu.
If „Factory Values“ is selected, the user calibration data will be
overwritten with the factory calibration values.
If „Factory Reset“ was activated, the user calibration data of all 4-20mA-
