ACCURACY AND CALCULATION EXAMPLES

■ Overall Accuracy
The accuracy includes input accuracy, which converts the sensor input into a digital value, and output accuracy, which converts the digital value into an analog signal.
The accuracy of the device is the total of the input accuracy and the output accuracy.
Input accuracy
Accuracy of each input is as table 1.
For RTD, the table or ±0.05 % of setting value span, whichever is greater.
For thermocouple, add CJC error 3℃ to the above.
Output accuracy
Output accuracy for the setting value span is shown as following formula.
Output accuracy = (output range ÷ output setting value span) × 0.02 %
For current output,
Output accuracy = (output range ÷ output setting value span) × 0.04 %
Calculation examples
Ex1: RTD Pt 100 0 - 500℃, output 4 - 20 mA
Input accuracy = 0.15℃ ÷ 500℃ = 0.03 %
0.03 % < 0.05 % -> input accuracy is 0.05 %
Output accuracy = (20 mA ÷ 16 mA) × 0.04 % = 0.05 %
Accuracy = input accuracy 0.05 % + output accuracy 0.05 % = 0.1 %
Ex2: K thermocouple 0 - 700℃, output 0 - 10 V
Input accuracy = 0.5℃ + CJC error 3℃ = 3.5℃
3.5℃ ÷ 700℃ = 0.5 %
Output accuracy = (20 V ÷ 10 V) × 0.02 % = 0.04 %
Accuracy = input accuracy 0.5 % + output accuracy 0.04 % = 0.54 %
