Inrush Current Clamp Multimeter, BTMETER BT-570N TRMS 5999 Display Clamp-on Amp Meter voor AC/DC Spanning, Stroom, Weerstand, Temperatuur Test

Habe das Teil zurückgeschickt. Man kann sich aussuchen was für einen "gemessenen" Wert man möchte. Angezeigt wurden sogar negative! Ströme. Für mich unbrauchbar

The brand new pp9 battery that came with it still shrink wrapped was dead out of the box. It took a while to realise that is why the meter didn’t switch on. A new one solved that. The instructions are not the best but not the worst. I bought it to measure currents on vehicles and I haven’t yet tried that.

The actual unit seemed fairly well made , with smoothed edges etc, not rough to hold .However the accuracy was somewhat poor, maybe just a faulty unit,.not an expensive unit, having purchased other dvm's over time, for similar money ,with better accuracy.

The meter worked but its accuracy is poor, wish I'd spent more andbought a different one to be honest, sorry, but it's not very good for the price

As a standard voltmeter it seems to work fine. The idea of the bluetooth sounds good but I did not use it (I just saw it while writing this review), so untested by me. The clamp contactless measurement doesn't produce any measure at levels in the 120V and 4-10A range. The seller claims it should measure though at a low resolution at those levels as this is apparently optimal for measuring really high currents, but should still have a resolution of 0.1A, which it obviously does not. As an auto ranging meter it would be nice if it would handle lower currents. It worked fine with lower currents and voltages using standard leads however. Maybe mine is faulty. I will return it. Otherwise nicely packaged and works, I wish it worked for me. It really has quite a few features but I have other basic volt-ammeters that do all the rest, except the bluetooth.I'll add that I feel a bit mistrustful of this because it seemed like it was measuring fine so I used it when I was upgrading a light fixture from fluorescent tubes to LED, and I tested using the probes if I had successfully determined the right breaker to switch off. It measured no voltage across the incoming AC wires, so I went ahead to cut the wires with my cutter, and happened to capture both at once. Well AC was not off and I luckily was only touching the insulated part of the cutters as a huge spark happened and now those cutters have a nice hole in them. There is a slight chance that the probes were not properly in contact but I thought they were and I'm pretty careful when it comes to AC current. Again I probably received a faulty unit and it's not an essential tool for me otherwise I'd work with the seller to get a proper one as they seem responsive.
