Abstract
An apparatus and method for displaying pressure on electrically driven analog-display pressure gauges. A diagnostic service equipment for a vehicle having a refrigerant system, the refrigerant system having a plumbing circuit for transferring a refrigerant between the diagnostic service equipment and the refrigerant system of the vehicle; a high side refrigerant conduit having a first connection, a second connection and a third connection, wherein the first connection is connected to the plumbing circuit and the second connection is connected to the refrigerant system; a low side refrigerant conduit having a first connection, a second connection and a third connection, wherein the first connection is connected to the plumbing circuit and the second connection is connected to the refrigerant system; and pressure transducers attached to each of the third connection of the high side refrigerant conduit and the low side refrigerant conduit, wherein the pressure transducers measure pressure of the high side and low side refrigerant conduits and convert the pressure into electrical signals to drive an analog-display pressure gauge.
