    Ein Lob an Fnirsi, toll.

    Das Gerät ist wertig und stabil. Der Touch Screen Monitor ist toll funktioniert perfekt. Die Genauigkeit ist gut für den Preis ebenfalls toll. Leider keine deutsche Gebrauchsanleitung. Würde das Gerät sofort wieder kaufen, ich kanns nur empfehlen auch für den täglichen Gebrauch, sehr gut. Danke auch für Eure Beschreibung.

    Das Gerät funktioniert einwandfrei.
    Nur die Funktionsbeschreibung könnte etwas ausführlicher sein.
    Ich habe einige Zeit gebraucht, bis ich herausbekommen habe, wie man beim Generator die Kurvenform festlegen kann.
    Masn muß die angzeigte Kurve berühren - dann erscheint ein neues Fenster, indem man die gewünschte Form auswählen kann.
    Ansonsten gibt es nichts zu meckern.
    Besten Dank

    I am testing this device,just received, is compact and nice to portable everywhere. Is simple to use, suggest to add more languages for UI, the same things fonthe manual(available in few lamguages).

    Durchaus ein interessantes Gerät

    Punktabzug gibt es wegen der mangelhaftende Gebrauchtanweisung. Diese ist nur in vier Sprachen erhältlich und sehr knapp ausgeführt. Wer öfters mit einen Oszilloskop arbeitet kommt auch ohne ausführliche Anleitung klar. Bei einigen zusätzlichen Funktionen wäre einfacher nachzulesen als tausend mal probieren wie es tatsächlich funktioniert. Das hätte mir die Funktion der Frequenzganganalyse erheblich erleichtert. Ein Nachteil bei der Funktion Frequenzganganalyse ist die automatische Skalierung des Diagramms und kann nicht manuell festgelegt werden. Das kann die Interpretation der Messergebnisse leicht verwirren und erfordert darüber gewisse Erfahrungen. Sonst ist für diese Preisklasse ein ordentliches Gerät mit guter Genauigkeit und ist durchaus empfehlenswert.
