Abstract
Abstract A sensor 13 is inserted into a connector 14. A constant voltage required to obtain a response current is applied across the connector 14 by a voltage applying source 15 at timings required. A response current of the sensor 13 inserted into the connector 14 is converted into a voltage by a current-to-voltage converter 16, and the amount thereof is determined by a microcomputer, the analysis results being displayed onto a display unit. <IMAGE>

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
86 words
A quantitative analyzing apparatus comprising: means for applying a reaction voltage to a sensor (13), means for detecting that a sample liquid is supplied to said sensor (13), means for interrupting the reaction voltage on the basis of output of said detection means, means for reapplying said reaction voltage to said sensor (13) after said interruption means has operated for a specified time period, means for detecting a reaction state of said sensor (13) due to the reapplication thereof, and means for displaying the reaction state.
Claim 2
Dependent Claim
39 words
A quantitative analyzing apparatus as claimed in claim 1, the apparatus further comprising means (20) for detecting that a sensor (13) has been mounted to the apparatus, wherein said reaction voltage application means is driven by the detection thereof.
Claim 3
Dependent Claim
50 words
A quantitative analysis apparatus as claimed in claim 1 or 2, wherein said reaction voltage application means is a current-to-voltage converter, and said reaction state detection means makes a decision with a CPU on the basis of output of said converter adapted to analog-to-digital convert output of said current-to-voltage converter.
