Review: J'ai mesuré quelques composants dont les JFET. La réponse de l'appareil : c'est un JFET et indique la Gate, c'est totalement insuffisant comme indication ! J'avais utilisé auparavant un DCA75 qui me donnait entièrement satisfaction. Je pensais que seul le transfert vers un PC faisait la différence. La notice est mensongère.
Review: Si te dedicas a la electrónica debes tener varios comprobadores y tésters, incluso un osciloscopio, pero si no tienes un MUY BUEN comprobador de transistores, tienes un problema. El analizador de semiconductores Peak DCA55 analiza transistores de germanio y silicio, diodos, LEDs, MOSFETs, JFETs, etc... En electrónica es importantísimo obtener la ganancia y fuga de un transistor, ya que cuando se compran, aunque tengan la misma referencia, los valores son distintos y pueden variar mucho entre unos y otros, por eso es tan importante un analizador como éste.

## Questions & Answers

**Q: Can this measure resistors and capacitor? If not does atlas make one that does test both ?**
A: This Atlas model doesnot measure resistors and capacitor, but you can do it with the Mega 328 ESR transistor, resistor, diode, capacitor and mosfet tester for less than $15.00 .

**Q: Does this only identify the component or does it test it as well?**
A: It not only identifies the type of transistor but gives you key current/voltage and gain characteristics also.

**Q: Will this device check or test and specify thyristors?**
A: Yes.

**Q: Is this version 3.0?**
A: Mine is a version 2.93 but I bought it in Jan 2013!!  Not sure what the current selling rev is..
