    Default Resolution of V1/V2 A/D inputs?

    Wondering, what resolution do the 5V A/D inputs of both V1 and V2 have?

    V1 and V2 have a resolution of 4.88mV and an accuracy of +/- 10mV

    Yes, I should have just said that

    The V1 has a 4.8V limit due to protection circuits.

    The V2 has the full 5.0V range. The signal is passed through an opt isolator amplifier to boost the signal back to the full 5V range. The V2 has the option to be calibrated due to small variations in the opto isolators.
