    Macht was es soll, zeit informativ auf dem großen Display alle relevanten Bauteildaten an. Perfekt! Ab sofort immer im Einsatz. Am besten mit Gehäuse bestellen oder selber aus einem kleinen Gehäuse einen Schutz bauen.

    Es ist erstaunlich wozu der Atmega328 in der Lage ist. Es ist natürlich kein High End Messgerät aber für den Hobby bereich mehr als Ausreichend.

    Klar ist das Teil kein Profi-Gerät und passive Bauteile kann man auch mit einem vernünftigen Multimeter messen. Aber dieses Gerät spart enorm Zeit, wenn man Widerstände sortieren muss oder im Wust seiner Werkstatt gerade nicht weiss ob es sich um einen NPN oder PNP-Transistor handelt. All dies erkennt dieses Gerät sehr zuverlässig und vor allem schnell. Gerade für Hobby-Elektroniker ein sehr zu empfehlendes Gerät: Kostengünstig. Erfüllt seinen Zweck und spart Zeit, die man besser in sein Projekt stecken kann als ewig mit dem Multimeter rumzumessen.

    Für Transistoren, FET,LED, Widerstände, Dioden, Kondensatoren etc funktioniert super und erspart viele andere Messgeräte. Toll was mit moderner Computer-Technik möglich ist. Zeigt auch an welche Anschlüsse wo sind zB Basis Kollector Emitter beim Transistor Es gibt ein ähnliches Gerät für IC's speziell einfache Standard IC's :
