Abstract

In a connector apparatus used to a measuring apparatus, a method for connecting a sensor to the measuring apparatus is standardized without any calibration. The connector apparatus is arranged by comprising: a measuring apparatus for storing therein a read command program: a connector containing a ROM (read-only memory) from which a measurement item is readable in accordance with the read command program stored in the measuring apparatus; and a sensor connected to the connector and operable in accordance with the measurement item read out from the ROM.

Claims

1. A connector apparatus comprising:

a connector having a plurality of plugs to be connected to a plurality of corresponding jacks provided in a measuring apparatus, and a PROM having stored therein one of a plurality of measurement identification codes to be outputted through first plugs of the plurality of plugs to corresponding first jacks of the plurality of jacks;

a sensor connected to second plugs of the plurality of plugs of the connector and having an LED and a light receiving element for sensing a light quantity as measured data received by the light receiving element from the LED;

a ROM having a stored read command program to read out said one measurement identification code from the first jacks and having a stored correction calculation program to correct the measured data sensed by the sensor;

a sensor pulse transmitting circuit controlled by the correction calculation program for transmitting a sensor pulse via second jacks of the plurality of jacks corresponding to the second plugs to the sensor to produce said measured data on said second plugs and said second jacks;

a background noise eliminating circuit for eliminating background noise from the measured data input via the second plugs and the second jacks from the sensor to output sensing data;

a sensing data shaping circuit for shaping the sensing data output from the background noise elimination circuit,

an EEPROM containing a correction table having a stored plurality of correction data corresponding to the plurality of measurement identification codes so that one of said plurality of correction data corresponding to the one measurement identification code is used by the correction calculation program to correct the measured data in the shaped sensing data;

a corrected data outputting circuit for outputting the corrected measured data as corrected in accordance with the correction calculation program; and

a display for displaying the corrected measured data supplied from the corrected data outputting circuit.

2. A connector apparatus as claimed in claim 1 wherein the plurality of correction data each includes an addition factor and a multiplication factor for correcting the measured data.
