Abstract
A calibration apparatus includes a microcomputer-based calibrator unit, functioning separately from a measuring device to be calibrated, and a coupling coil, through which calibration information generated by the calibrator unit is electromagnetically transmitted to the measuring device to which the coil is strapped or otherwise connected. This permits the measuring device to be calibrated without the measuring device being removed from the environment in which it is to make measurements. The methodology of the apparatus permits the measuring device to be calibrated either with standard calibration data, such as whereby the measuring device is calibrated to a factory standard calibration, or with variable calibration data, such as whereby a then-current calibration of the measuring device is 'tweaked'.
