Determining
Effective
Resolution and
Range
The effective resolution for an input channel depends upon the filter
frequency selected for that channel. The following tables provide the
effective resolution for each of the range selections at the six available
frequencies. The tables do not include the affects of unfiltered input noise.
Choose the frequency that most closely matches your requirements.
