Abstract
A modular metering instrument including one of a plurality of sensing probes or probe modules including identification and calibration information stored therein and a meter module which can identify the sensing probe when the sensing probe is connected thereto. The storage of calibration and identification information in the sensing probe allows the meter module to be utilized with any one of a number of sensing probes to sense different physical parameters. The sensing probe includes at least one sensor and related circuitry to generate a signal relating to the sensed parameter. The meter module analyzes and calibrates the signal and displays the measured parameter.
