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
Input accuracy for the setting value span is shown as following formula.
Input accuracy = (input range ÷ input setting value span) × 0.01 %
For current input,
Input accuracy = (input range ÷ input setting value span) × 0.02 %
(Use the larger one when input 1 accuracy and input 2 accuracy are different.)
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
The overall accuracy is ±0.1 % when following setting.
K0 = 0.5, K1 = K2 = 1, A0 = A1 = A2 = 0 %
Input 1: input range  -10 - +10 V, input setting value span
0 - 5 V
Input 2: input range  0 - 50 mA, input setting value span
0 - 20 mA
Output: output range 0 - 20 mA, output settin value span
4 - 20 mA
Input 1 accuracy = (20 V ÷ 5 V) × 0.01 % = 0.04 %
Input 2 accuracy = (50 mA ÷ 20 mA) × 0.02 % = 0.05 %
Output accuracy = (20 mA ÷ 16 mA) × 0.04 % = 0.05 %
Input 2 accuracy (0.05 %) is larger than input 1 accuracy (0.04 %), the overall accuracy is input accuracy 0.05 % + output accuracy 0.05 % = 0.1 %.
