Component Tester

The last project that i built it is a component tester, which is based on AVR-Transistortester by Mark Frejek
And here is the modified version further developed by Karl-Heinz Kübbeler.
You'll find all firmwares and  documentation  at http://www.mikrocontroller.net/svnbrowser/transistortester/.

Here is the schematic:


 The PCB layout:

And here is the final result:



Here is a list of the parts used in this project:

Software Version 1.07k Specifications:


Measurment Range: 
   -Resistor:0.5Ω - 50MΩ.   
   -Capacitor:25pF - 100000uF.
   -Inductance:0.01mH - 20H.
 Features:
  -Operates with ATmega8, ATmega168 or ATmega328 microcontrollers.
  -Automatic detection of NPN and PNP transistors, N-channel and P-channel MOSFET, diode (including dual diode),Thyristor,Transistors, resistors and capacitors.
  -Automatic detection of pin layout of the detected part.
  -Measuring of current amplifcation factor and Base-Emitter threshold voltage of bipolar transistors.
  -Detection of the protection diode of bipolar transistors and MOSFETs.
  -Measuring of the Gate threshold voltage and Gate capacity value of MOSFETs.
  -Resolution of resistor measurement is now up to 0:01 values up to 50M are detected.
  -For resistors below 2100 also the measurement of inductance will be done,
  -Capacitors with values from 25pF to 100mF. The resolution can be up to 1 pF .
  -For capacitors with a capacity value above 0:18 F the Equivalent Serial Resistance (ESR) is
measured with a resolution of 0:01Ω.
  -For capacitors with a capacity value above 5000pF the voltage loss after a load pulse can be
determined. The voltage loss give a hint for the quality factor of the capacitor.
  -Zener-Diodes can be detected, if reverse break down Voltage is below 4.5V. 
  -LED is detected as diode, the flux voltage is much higher than normal.
  -Selectable facility to calibrate the internal port resistance of port output and the zero of set
of capacity measurement with the selftest.
  -Display battery voltage
