If your sensor is giving you false readings, you may need to clean and/or calibrate the sensor. Use the uPyxis app to conduct rapid cleanliness diagnostics. Your sensor will read ‘Clean’ or ‘Dirty’. If your sensor is dirty, conduct the cleaning & calibration procedures found in your user manual or maintenance guide (click here to find support documents). If your sensor is clean & calibrated but still reads incorrectly please request repair or contact us.
