Note: Each error status is determined by the corresponding bit (b0 ~ b13) and there may be more than 2 errors
occurring at the same time. 0 = normal; 1 = error
Adjust A/D Conversion Curve
You can adjust the conversion curves according to the actual needs by changing the Offset value (CR#28 ~ CR#31) and
Gain value (CR#34 ~ CR#37).
Offset: The corresponding voltage/current input value when the digital output value = 0.
Gain: The corresponding voltage/current input value when the digital output value = 16,000.
