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:
CR1000 module temperature,‐25 to 50°C
Temperature = 45°C
Reference temperature = 25°C
Delta T (temperature difference) = 20°C
Thermocouple output multiplier at 45°C = 42.4 µV °C ‐1
Thermocouple output = 20°C * 42.4 µV °C ‐1 = 830.7 µV
Input range = ±2.5 mV
