Verify the opening in the duct is properly sized for the valve and installation method being used. Also verify both ends of the duct where the valve is to be attached are true and square before attempting to install valve. If the duct ends are not square and true, do not attempt to install valve as it will not operate properly.

- Page 19 Installation & Operation Manual - Model AVT4000 6.5.2 Airflow Volume Gauge The Airflow Volume Gauge provides the real-time measurement of the volumetric air flowing through the AccuValve. The range of this gauge is determined by the size of the valve and it cannot be reset in the field.
- Page 20 Installation & Operation Manual - Model AVT4000 6.5.4 Analog Output Configuration The AVT’s Analog Output is primarily used to provide an analog signal representing the Airflow Volume flowing through the valve. The signal type and full-scale range of the Analog Output are user-defined values that are configured by clicking on the boxes adjacent to each heading.
- Page 21 Installation & Operation Manual - Model AVT4000 6.5.5 Sensor Frequency Signals The AccuValve measures airflow using vortex shedders that are incorporated in the compression zone of each chamber inside the valve. Each vortex shedder provides an independent frequency-based signal that is directly proportional to the air flowing through the chamber.
- Page 22 Installation & Operation Manual - Model AVT4000 TOOLS Adjustment ➢ Balancer Offset: Provides a simple tool for correlating the transmitter airflow measurement to a field measurement in one step. This offset is applied as an Equal % Cal. Adj. which does not overwrite the factory calibration of the AVT4000.
