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”.

An apparatus for calibrating a measuring device, said apparatus comprising: calibration signal generating means for generating, independently of the operation of the measuring device, a calibration signal, the calibration signal generating means comprising: power supply means for providing electrical energy to said apparatus; switch for activating said power supply means; and timer means, having a time period which expires if the time period is not restarted prior thereto, for automatically deactivating said power supply means when said time period expires; and communicating means for communicating said calibration signal to the measuring device without disassembling the measuring device.
