ACCURACY AND CALCULATION EXAMPLES

■ Overall Accuracy
The accuracy includes output accuracy, which converts the setting accuracy and digital value into an analog signal.
The accuracy of the device is the total of the input accuracy and the output accuracy
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: Output 4 - 20 mA
Output accuracy = (20 mA ÷ 16 mA) × 0.04% = 0.05%
Accuracy = setting accuracy 0.1% + output accuracy 0.05% = 0.15%
Ex2: Output 0 - 10 V
Output accuracy = (20 V ÷ 10 V) × 0.02% = 0.04%
Accuracy = setting accuracy 0.1% + output accuracy 0.04% = 0.14%
