I've been looking into the cause of the wildly inaccurate readings. Took ages. Getting a Vf of 220mV for a 1N4148 finally made me look in the right place. I haven't found out why, but I have found out where. The averaging code in ReadU is borked. Quick hack (though you theoretically loose accuracy Ha Ha) is to change ADC_SAMPLES to one:
#define ADC_SAMPLES 1
Magically, it works. Readings are not as consistent, but a LOT more accurate.

Re: Ardutester - Arduino Component Tester
I have adapted the latest version of TransistorTester V 1. 13 to the Arduino IDE !!!
so its now the ArduTester V1.13
The project files are in the online web Editor :
Read the ReadMe.adoc for Hardware details. ...
