1. Automatic detection of NPN and PNP transistors, field effect transistors, diodes, double diodes, SCR, automatic recognition of transistor pinch?out, SCR can just identify their pinch?out, and the trigger current of the SCR that needs to be tested is less than the current that the tester can provide, and the tester can just provide the maximum trigger current of 6mA.
2. Test NPN and PNP transistor common emitter current amplification factor, base electrode?emitter electrode threshold voltage, collector?emitter electrode leakage current.
3. Identify Darlington transistor by transistor base electrode?emitter electrode threshold voltage and high current gain. Separate capacitance function test, the test mode of continuous measurement of 2uF?50mF capacitors can be directly measured in its circuit (measuring power required by capacitance in the circuit, after measuring capacitance totally discharged).
4. The display unit adopts 160x128 color display, full?screen characters 8x20, 16?bit color depth, and graphic elements display symbols, rotation switch control, one?button measurement, automatic shutdown.
5. Use 9V laminated battery, you can also use power adapter (DC 6.8?12V), the total current is about 30mA, and then about 20nA shutdown current.
6. DC voltage measurement up to 50V, output signal throughout the whole process, with multiple ranges of frequencies to choose from, the maximum output frequency is 2MHz, output a fixed frequency, variable duty cycle pulse signal (PWM), the duty cycle is adjustable from 1% to 99%.
