Typical and warranted accuracy by input range and temperature
range
Note Full scale is the maximum value of the nominal
input range. For example, for the ±10 V input range,
full scale is 10 V and ±0.01% of full scale is 1 mV.
Gain error drift..................................±20 ppm/°C
Offset error drift................................6 µV/°C
