Notes:
[1] Resolution is user-selectable. The maximum available resolution for each range is shown.
[2] Valid for inputs above 10% of the maximum input.
[3] Valid for inputs from 1% to 10% of the maximum input. Inputs less than 1% are not specified.
[4] Fail-safe current is 7.5mA on all ranges if range 1 is installed, otherwise 750µA all ranges.
