Dieser einfache Transistortester auf Platino-Basis testet zweifelhafte und/oder nicht gekennzeichnete Transistoren auf Funktion und ermittelt den Verstärkungsfaktor, damit auch Transistorpärchen ausgemessen werden können. Das Gerät ist für NPN- und PNP-Bipolartransistoren sowie für n- und p-Kanal-MOSFETs geeignet.

Specifications:

  • DC Input: 12V to 18V DC.
  • Elektor Platino with ATMEGA32 microcontroller.
  • 20 X 4 LCD Display.
  • Elektor’s USB to Serial BOB module interfacing for debugging.
  • Pluggable terminal block for easy mounting of transistor device to be tested.

Features:

  • Identifies transistor type, leads and characteristics.
  • Indicates faulty or no transistor.
  • Results can be viewed on LCD as well as serial terminal simultaneously.
  • Easy and portable design.
