Different combinations of the notched and unnotched positions, or the holed and unholed positions, on the identification area create different digital identification signals. After the test strip is inserted into the test instrument, the test instrument will obtain the digital identification signal and learn the test code, analysis parameters, expiry date and batch number of the test strip. Thereby, the test instrument can verify the batch number and expiry date of the test strip, perform calibration according to the analysis parameters, and provide a correct test result. The present invention can provide many sets of digital identification signals to differentiate test strips. Therefore, the present invention can be operated fast, conveniently and correctly and can prevent a user from forgetting to calibrate the test instrument. |
