The AV-622 is a single-point, multi-range Air Velocity Transmitter with user selectable 0-10Vdc or 4-20mA outputs and four user selectable measurement ranges.
The unit has a built-in self-test feature and the user can manually override the output to 0%, 50% or 100% of output range to aid commissioning.
