This transistor tester can test all commonly used electronic components. All tests are recognized intelligently, and it can display the circuit symbols, pinouts, main parameters of the device under test in an intuitive graphical manner.

Features:
Built-in ATMEGA644 main control chip, higher accuracy and more stable performance.
LCD display with backlight for easy reading.
With one-button and rotary encoder for convenient operation.
Automatic detection of resistors, capacitors, inductors, diodes, LEDs, transistors, FETs, IGBTs, thyristors, etc.
Test the pins of a component and show on the display automatically.
With a typical ESR value, convenient to judge the detected capacitor's quality.
Includes Low/High-frequency Crystal Oscillators, can test all kinds of crystal oscillators from 32.768KHZ to 20MHZ.
Can measure the working voltage of Zener diodes with a stable voltage less than 44V.
External DC Voltage Test, can measure DC voltage within 50V.
Can be used as frequency meter and frequency generator.
