1.2 Range Configuration Code
The AD converter of the OME-A-826PG is 16 bits under all
configuration code. If the analog input range is configured to ±5V range, the
resolution of one bit is equal to 2.44 mV. If the analog input range is configured to
±2.5V range, the resolution will be 1.22 mV. If the analog input signal is about
1 V, use configuration 0/1/2 (for OME-A-826PG), it will get nearly the same result
except resolution. So choose the correct configuration code can achieve
the most high precision measurement.
