    The item is perfect! I bought many same, but this is the best for my camper. Some thing is missing from the manual! You can calibrate the current and the voltage zero point. After I install, the meter is not correct, but after I found this setup, everything is good! The calibrate menu is same but the language and wireless channel setup, but is in the upper hidden menu. Thanks again!

    Nach erfolgter Reklamation hat mir der Verkäufer anstandslos (!) ein zweites Gerät geschickt und obwohl -Übersee- keine Versandkosten oder Rücksendung gefordert. Ich nenne das kundenfreundlich hoch drei !!! Die Anzeige und das Messgerät arbeiten einwandfrei und zeigen bessere und genauere Daten als mein Verbautes. Die Bedienung ist trotz englischem kinderleicht.
