The factory recommends that you calibrate your sensors every two years for a few reasons. Electronic drift happens over time with sensitive instruments. Also, dust accumulated in ductwork contains large amounts of organic materials such as fungal spores. The foreign particulates can build over time resulting in restrictive air passages and inaccurate pressure readings. Calibrating your sensors will ensure it meets the reliability specifications of Triatek.
