Abstract

The invention discloses a detection system capable of automatically switching the detection voltage and a voltage calibration detection method of the detection system capable of automatically switching the detection voltage. The detection system comprises a testing device and a graph calculation device. The testing device can selectively output a first voltage and a second voltage. When executing an analog digital conversion calibration procedure, the graph calculation device transmits a first testing command to the testing device to receive the first voltage output by the testing device according to the first testing command and execute a first-stage calibration procedure, and transmits a second testing command to the testing device to receive the second voltage output by the testing device according to the second testing command and execute a second-stage calibration procedure. The analog digital conversion calibration procedure includes the first-stage calibration procedure and the second-stage calibration procedure.

Description

technical field [0001] The invention relates to a detection system and method, in particular to a detection system capable of automatically switching detection voltages and a voltage calibration detection method thereof. Background technique [0002] Graphing calculator (Nspire) models are in production, ADC Calibration needs to sample ADC through two voltages of 3.0 volts (v) and 4.0 volts (v), and use software to convert ADC calculations through formulas Generate a voltage, and then judge the detection information of the result (pass or fail). Finally, the synthesis of the detection information of the 3.0v and 4.0v test results can finally determine whether the ADC Calibration has passed or failed. [0003] In the current existing test methods, the detection of ADC Calibration is realized by manually switching the 3.0v and 4.0v respectively provided by the two channels of the power supply. However, this manual method of detection has the following disadvantages: [0004...
