ABSTRACT:
The present invention includes a portable, damage resistant, palm-held, low cost, high sensitivity ergonomically dimensioned digital remote gauge assembly unit for the measurement of external parameters that include by way of example temperature, pressure, and vacuum; a kit having a digital remote gauge assembly unit, a variety of probes and adapters that provide for the communication signals to the unit in response to externally measured parameters, and a communication link between a respective probe and the digital remote gauge assembly unit; and, a method of utilizing the kit and device to facilitate the rapid measurement of a variety of external parameters. The digital pressure gauge includes a gauge body dimensioned to be held in the palm of a user's hand. The gauge body has microprocessor controlled circuitry therein, an altitude and temperature compensated pressure transducer in communication with the microprocessor, and keys for actuating the microprocessor. The body also includes a display for informing the user of readings taken in a mode of operation of the device, a probe assembly; and, a multi-conductor shielded cable connecting the gauge body and the probe assembly. The gauge also includes routines providing a plurality of the modes of operation of the gauge including a PSI mode, a KPA mode, a PEAK HOLD mode, a HI/LO resolution mode, and a temperature mode in which the display presents a temperature of a fluid being tested in either .degree.C. (Centigrade) or .degree.F. (Fahrenheit).
