Regarding calibration: The card has an open calibration feature meaning that the customer has access to the feature and can use it for system calibration. When higher accuracy is needed, it is recommended to conduct a system calibration including cables and connectors.

Option - ADC that measure applied voltage, can be read, but also act as a protection mechanism for the board, open relays if applied voltage is too high.
