Question

Why is my sensor showing the error 'Over-range'?

Answer  

The Over-range error means that the value the sensor has detected is greater than the maximum value that it can correctly measure.   

Overview

The Over-range error can be reported on any device that has an operating range. 

For example, a Generic 4-20mA sensor has a range of 4-20mA. If the sensor detects a reading greater than 20mA, it will report an over-range error.

This error can occur if the physical reading is actually beyond the maximum value that the sensor can correctly detect, or if the sensor has failed.
