Transistor tester control
1.The tester is controlled by a rotary encoder switch.
2.The rotary encoder switch can be operated in a total of 6 ways, short press, long press, left turn, right turn, press and hold left turn, press and hold right turn.
3.A short press in the off position turns the power on and starts the test.
4.After a test has been completed, if no device is detected. Press and hold the switch or rotate the switch left or right to enter the function menu. Once in the function menu, the left or right switch can be rotated up or down through the menu items, to enter a particular function item, press the switch once short. When it is necessary to exit from a certain function, then press the switch long.

Test Devices
The tester has 3 test points, TP1, TP2 and TP3, which are distributed in the test stand as follows
On the right hand side of the test stand are the test positions for the SMD components, with the numbers 1,2,3, each representing TP1, TP2 and TP3 respectively.
When testing components with only 2 pins, the pins are not divided into test order, 2 pins are chosen for any 2 test points, and the pins of 3-pin devices are placed in three test points, in no particular order. After the test, the tester automatically recognises the pin name of the component, the test point where it is located and displays it on the screen.
When testing components with only 2 pins, if two test points are used, TP1 and TP3, the tester automatically enters continuous test mode after the test is completed, so that the components on TP1 and TP3 can be measured continuously and simultaneously without having to press the switch again. If “TP1 and TP2” or “TP2 and TP3” are used, only one test is performed. To test again, press the switch once.
