Figure 95: Input error calculation
Input Error Examples: Type T Thermocouple @ 45°C
These examples demonstrate that in the environmental temperature range, input-
offset error is much greater than input-gain error because a small input range is
used.
Conditions:
CR1000moduletemperature,25to50°C
Temperature=45°C
Referencetemperature=25°C
DeltaT(temperaturedifference)=20°C
