OME-A-826PG Software Manual [Win 95/98/NT] 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 t
