Gauge with visual calibration confirmation and related method

A device comprising:

• first means comprising a first needle connectable in communication with a HVAC system, the first needle visually displaying a first pressure reading of the HVAC system;
• second means drivingly coupled to the first needle for moving the first needle to positions corresponding to respective first pressure readings of the HVAC system;
• and
• third means electrically coupled to the second means for moving the first needle from a first position to at least one second position at least one of (i) during calibration, and (ii) following calibration, of the first means where at least one of the first position and the second position of the first needle are not indicative of pressure in the HVAC system, and to move the first means to a zero position.

A method comprising the following steps:

• connecting 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 at least one of (i) during calibration, and (ii) following calibration, of the first gauge where at least one of the first position and the second position of the first needle are not indicative of pressure in the HVAC system, and to move the first needle to a zero position;
• calibrating the first gauge;
• and
• during and/or following calibration of the first gauge, visually confirming calibration by moving the first needle of the first gauge from the first position to the at least one second position.
