must have

The necessary device to check the servo. Checked all the servo's on the planes, found one with an over-current.

unreliable

Otherwise all functions ok.
But unreliable drive.
Voltmètre not trustworthy by 1v !!!!! 5.72v (HobbyKing) for 4.95v (multimètre).

Love it.

I went too long without having a watt meter. While the sampling frequency means that it may not be perfectly accurate, I soldered some adapters and used it to test the battery draw on my 2s and small 3s foamies, and it's REALLY useful to get real data! I still need accurate readings on some of my heli servos and haven't tried that yet. It may not give perfectly accurate momentary peaks, but I feel like by just watching it you can get a pretty good sense of the average peak, if that makes sense. For the money, it's good either way.

not worth the money

Got one of theese, always shows wrong Amp values, voltmeter also not too accurate.
Amperemeter very slow, means, a peak in current, typical for servos, you will never see.
After 20 min working, the product shows nothing anymore.
Could be a nice instrument, if an optimized software comes in and if it gets reliable.
Work on it.

Thanks.

With a different connector, this can be used for testing motor and other load, not just servos. I do recommend everyone to get it, since it's cheap, and can percent a lot of pain with servos.

Ich habe eins dieser Wattmeter gekauft. Anzeige immer 1300A !! also, defekt und zurck geschickt. Trotz mehrfacher Nachfrage kein Ersatz und kein Geld zurck. Ich bin zum erstenmal vom Service entteuscht. 2 Monate spter das gleiche Messgert noch einmal bestellt. Beim Anschlu eines Serves mit zustzlich dazwischen geschaltetem Ampermeter zeigt das Ampermeter 300mA an und das Wattmeter 2,5A!!! also ein total falscher Wert.
Schade, ich war bisher immer mit HK zufrieden, aber dieses Wattmeter ist fr die Tonne.
Ich werde es nicht zurck schicken. Die Portokosten wren dann auch weg.
