(1) The over- or under-range flag will come on when the normal operating range (over/under) is exceeded. The module will continue to convert the analog input up to the
maximum full scale range. The flag automatically resets when within the normal operating range.
(2) Resolution is dependent upon your filter selection.
(3) Rated working voltage is the maximum continuous voltage that can be applied at the input terminal, including the input signal and the value that floats above ground
potential (for example, 10V DC input signal and 20V DC potential above ground).
(4) For proper operation, the plus input terminals must be within ±10V DC of analog common.
(5) Includes offset, gain, non-linearity and repeatability error terms.
(6) Repeatability is the ability of the input module to register the same reading in successive measurements for the same input signal.
(7) Damage may occur to the input circuit if this value is exceeded.
