  An erratic reading on your Nuvair Measuring Instruments can occur due to several reasons. It might be caused by pressure on the sensor, so check the flow. Radio transmission interference could also be the culprit, in that case, move the unit away from potential sources of interference. Another reason may be that the sensor is old or faulty, consider changing the sensor. Finally, condensation on the sensor can cause this issue; try drying it in the air.
