ABSTRACT:
A reading meter (10) is capable of use with a plurality of different sensor heads (16, 16b). The reading meter (12) includes a digital display (20), a processor (22) and memory (23), and an analog-to-digital converter (ADC 41). Each different sensor head includes a memory (32a) which carries at least the processing algorithm for the particular sensor. In operation, the reading meter (12) reads the detector head memory (32a), and loads the information so read into its processor memory (23). The raw sensor data is converted to digital form, and processed in accordance with the stored algorithm, to produce the desired display. In one embodiment, the detector head memory (32a) is read, and the information is serially coupled to the reading meter. In another embodiment, the serial data is converted to optical signals (634) for transmission. The processor memory (23) may include other data which is held in semipermanent storage, such as calibration data for an ADC within the reading meter, and housekeeping information for the display (20). A count-down counter (52) in each sensor head is programmed with a number representing the number of days remaining in the calibration period, and is decremented daily.
