Abstract

Official abstract text for this publication.

A device for taking pressure readings on a HVAC system includes a first needle connectable in communication with the HVAC system for taking a first pressure reading thereof. The first needle is mounted within a first gauge and configured to self-calibrate. The device further includes a second needle connectable in communication with the HVAC system for taking a second pressure reading thereof that is independent of the first pressure reading. The second needle is mounted within a second gauge and configured to self-calibrate. A first stepper motor actuates the first needle and a second stepper motor actuates the second needle. A microcontroller controls the first and second stepper motors to move the needles to a plurality of respective positions and thereby visually confirm calibration.

First claim

Opening claim text (preview).

What is claimed is: 1. A device comprising: a first gauge including a first needle mounted thereon and connectable in communication with a HVAC system, the first needle visually displaying a first pressure reading of the HVAC system; a first motor drivingly coupled to the first needle for moving the first needle; and at least one microcontroller electrically coupled to the first motor and configured to move the first needle from a first position to at least one second position…
