1. The product has reliable performance, and the outer shell is made of aluminum alloy, with an overall size of 300X150X140mm.
2. It adopts a 7-inch color high-definition touch screen with a resolution of 1024X600, and all settings are set directly through touch.
3. The product operation is simple and easy to learn, just insert the key pad that needs to be tested, and the testing can be completed in two steps. The first step is to learn
Xi, after learning, save the data and use it again. Simply click on the menu "Open Document" to test it.
4. Membrane switch on-off test - directly test whether the Membrane switch is open or short circuited (Only one can be pressed at a time
Press the key, and if you press two or more keys at the same time, a warning prompt of "Port Exception" will appear
5. Resistance value test of Membrane switch - just set the upper limit and lower limit of resistance value in the new document. During the testing process
As long as the resistance value of a key exceeds the set limit, the corresponding button on the screen will display "X", and if it is qualified, it will display "OK"
6. LED test on the Membrane switch - when creating a new document, set the port corresponding to the LED as the LED port
Corresponding setting of LED positive and negative. After setting up, insert the test button and the corresponding LED will light up. It has been tested
Test whether the LED is soldered backwards or missed.
7. Insulation resistance test of Membrane switch - there is a key switch on the test fixture, which is specially used to test the insulation resistance
Insulation resistance refers to the insulation resistance value between the thin film film line and the line when there is no button pressed
This value will depend on the humidity of the weather and the distance between lines. Do not touch the test with your hands during testing
Test fixture and button chip circuit, otherwise the test will be inaccurate
The biggest advantage of BK910A is that by learning the master sample and saving it with a file name, it is possible to
Set the button position to the same as the master button position for easy comparison during testing.
9. Automatic save function, every time the computer is turned on, it will open the document from the last time it was turned off
10. The upper and lower resistance values can be set, and if the limit value is exceeded, the horn will alarm and PASS will be displayed
