An interoperable vacuum measuring device is presented, which automatically adjusts to one of two or more vacuum sensors having different electrical characteristics. The interoperable vacuum measuring device in a first step detects which type of vacuum sensor it is connected to. In a second step it controls and evaluates the vacuum sensor, using control parameters determined in response to the detection of the first step. Detection of a vacuum sensor type is achieved by measuring the electrical resistance between any two pins of a vacuum sensor's connector and comparing the measured resistance values with stored resistance values of known vacuum sensors. Further, a vacuum measuring device is presented, which automatically identifies a vacuum sensor, and associates a vacuum pressure measurement with a vacuum sensor. The identification of a vacuum sensor is facilitated by an identification disk, which is placed onto and operatively connected to the male terminals of a vacuum sensor's connector.
