Notes:

The over- or under-range flag will indicate when the normal operating range is exceeded.
Resolution depends on the filter selection.
Rated working voltage is the maximum continuous voltage that can be applied at the input terminal.
For proper operation, both the plus and minus input terminals must be within ±10V dc of analog common.
Overall accuracy includes offset, gain, non-linearity, 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 may occur to the input circuit if this value is exceeded.
