    Dear Jarda!

    1) As shown above, the 0-10V inputs are nothing more than 2:1 resistive divider, correct? They are not documented in the manual nor on the pinout diagram.

    2) If we’d switch to the 2.56V reference, we could only measure 0-5.12V (2.56V * 2), right?

    3) Am I missing the secret pin to control the switch for the voltage divider on AI12 and AI13 from ratio 2:1 to ratio 3.90625:1?

    Greetings from Graz
