The over- or under-range flag comes on when the normal operating range (over/under) is exceeded. The module continues to convert the analog input up to the maximum full scale range. The flag automatically resets when within the normal operating range.
Resolution is dependent upon your filter selection. The maximum resolution is achieved with either the 50 or 60 Hz filter selected.
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, a 10V DC input signal and 20V DC potential above ground at the input terminal.
For proper operation, both the plus and minus input terminals must be within ?10V DC of analog common.
Includes offset, gain, nonlinearity, and repeatability error terms.
Repeatability is the ability of the input module to register the same reading in successive measurements for the same input signal.
Damage can occur to the input circuit if this value is exceeded.
