It is a graphic Mtransistor tester. It uses an ATmega3microcontroller. LCD display test. It can automatically detect PNP and NPN bipolar.
Here is a simple 5TIMER based circuit which will test the working of the transistor in seconds. Beside the semiconductor device analyzer, this meter can also work as an ESR meter, the ESR accuracy may not be able to . When a transistor is being tested (Sopen, Sin position or 3) a current will flow through the base-emitter junction of the transistor under test , . Here is a very simple circuit that can b e used to check the hfe of transistors. Transistor Tester.
Both PNP and NPN transistors can be . With a tester , you set up switches and controls and the meter shows you a. It features an in-circuit testing . When your project do not works, the tester electronic parts or component be what need very much. For the twenty-three euros you will not only get the transistor tester , but also three small test leads and a circuit board with a ZIF-socket for easy connection of .
