[0030] The eight wire interfaces 4 and the eight pin interfaces 3 are respectively named: S1, S2, S3, S4, C1, C2, C3, C4. The eight wire interfaces 4 correspond to the eight pin interfaces 3 one by one.

[0031] It further includes a potential difference test module, which includes an element naming module, a manual adjustment module, a data storage module, a collection range error reporting module, and a collection test module. The potential difference test module is connected to the stability test module 9.

[0034] The airtightness test module 10 also includes an I-t module for stabilizing voltage and an H22333 module for controlling the hydrogen injection capacity.
[0035] (1) When the stability test module 9 is active, the first power meter 7, the display 11, and the 2450 collector 12 are powered on:
[0036] The background for the need to conduct stability tests: After the components are produced, they need to undergo an aging process to reach stability. During the aging and aging process, the data changes of the components are monitored and recorded in real time by connecting them to a circuit for testing, and the data differences in different states and the long-term data change trends are compared, so as to clearly judge the stability of the components and screen out qualified or unqualified products.
[0037] The potential difference of the response compensation component is measured through a voltage-dividing circuit, and the size differences of the potential differences in different environments are compared, and whether the same response size can be achieved under multiple cycle conditions is used to judge whether the component has reached a stable state.
[0038] The operation process of the stability test module 9:
[0039] 1) Fix and install the test component 1 to be tested in the test cavity 2. The eight wire interfaces 4 of S1, S2, S3, S4, C1, C2, C3, and C4 on the circuit board 1 respectively correspond to the eight pin interfaces 3 of the test cavity 2, and each pair is respectively connected to a pair of response compensation components.
[0040] 2) After the installation and connection are completed, turn on the first power meter 7 connected to the first circuit board 5, adjust the voltage to 3.3V, and observe the current change of the first power meter 7 each time a pair of pin interfaces 3 is connected to ensure that an appropriate amount of current passes through each circuit.
[0041] 3) Turn on the second power meter 8 connected to the second circuit board 6 and adjust the voltage to 5V.
[0042] 4) Turn on the potential difference test module, first set and then run the program. Through the component naming module and the manual adjustment module, in the name or relative path column, name different test components 1 respectively (no default, must be set each time). The number of names and test components 1 should be consistent with the actual number of measured components, at least 1 and at most 4. In the acquisition number column, the quantity can be manually adjusted, and it should also be consistent with the actual number of test components 1;
[0043] 5) Save the corresponding data to the set file location through the data saving module. Set the file saving location in the path column. The tested and collected data will be saved at the set location (default, no need to set each time).
[0044] 6) After setting the file naming and quantity, click to run the potential difference test module and confirm the modified name again. When a 2450 collector 12 range error is prompted, click Continue and manually adjust the parameters on the 2450 collector 12. Modify the range as follows: Set the range to 10 nA in the SOURCE 1 box, set the source to 0, and set the limit to 2 V; also set the range to 2 V in the MEASUREVOLTAGE box. After adjustment, the test can be carried out.
[0045] 7) After setting the range through the acquisition range error reporting module, check the Clear Temporary Data checkbox and click the Start Acquisition button;
[0046] 8) Start collecting test data through the acquisition test module.
[0047] 9) Open the stepwise flow module, click to run, click Connect on the communication settings interface of the first page through the light-on module. At this time, the green light comes on, indicating normal serial port connection. Click Control 1 on the control interface, and the green light comes on. At this time, manually enter the gas flow rate of 500 in the gas flow rate column of the gas input module, click Flow Rate Settings, and Control 1 starts to display the real-time flow rate and cumulative flow rate. Start delivering air.
[0048] 10) Open the hydrogen charging and discharging module, click to run, and start delivering hydrogen through the flow meter 2 14.
[0049] 11) Wait for the test to be completed.
[0050] (2) When the airtightness test module 10 is active, the power meter 2 8, the display 11, and the 2450 collector 12 are powered on:
[0051] Background for airtightness test: During the production of the test component 1, there is a chance that a certain layer of film is not completely covered or has defective holes, which will affect the normal working response of the test component 1. Therefore, it is necessary to sample and test the airtightness of the test component 1 among the components produced in the same batch to ensure that the entire batch of test components 1 can be used normally.
[0052] When the test component 1 is in contact with a hydrogen environment, there is a great difference in airtightness. Therefore, it can be judged whether the test component 1 has good airtightness by monitoring whether the resistance of the test component 1 changes violently when in contact with hydrogen.
[0053] Operating procedure of the airtightness test module 10:
[0054] 1) Install the test component 1 to be tested in the test cavity 2. Each time the airtightness of the alumina film of the test component 1 is tested, only one test component 1 can be tested at a time. Only need to replace a pair of leads S1 and C1 and connect the test cavity 2 to the two 210V PEAK interfaces of the 2450 collector 12.
[0055] 2) Turn on the I-t module, click Run, and set the voltage to 1.65V in the Load Voltage column.
[0056] 3) Turn on the step flow module, click Run, click Connect in the communication settings interface through the light-on module, and the green light will turn on at this time. Click Control 1 in the control interface, and the green light will turn on. At this time, manually enter the gas flow rate of 500 in the gas flow rate column in the gas input module, click Flow Setting, and Control 1 will start to display the real-time flow rate and cumulative flow rate. Start delivering air.
[0057] 4) Wait for a period of time until the curve of the test component 1 in the air gradually stabilizes.
[0058] 5) Turn on the H22333 module, first manually enter the hydrogen injection amount of 20 in the setpiont (0-20) column, and then click Run Program.
[0059] 6) Wait for the test to be completed.
[0060] When this application is in use: between the stability test module 9 and the airtightness test module 10 through a relay, it can ensure that the tests between different test components 1 do not interfere with each other and can achieve automatic switching and cycling; the method of using test instruments in cooperation with an automated program greatly saves labor costs and tests batch components more efficiently and quickly.
