AUTO ZERO MODE
A sensor auto zero can be initiated by pressing and holding the internal <Auto-Zero> switch for at least
3 seconds. If both pressure ports are close to zero pressure, then the device will calibrate with a new zero
point. The auto zero can also be initiated by holding the ZERO IN terminal low for 3 seconds.
