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.
