I'm interested in this model only if it is real, but I not find it in any of the usual confident pages that I look. This is announced as the official store on aliexpress https://es.aliexpress.com/store/3095007 and I can't found the pro model, only the standard model is announced. Can you give me the link to the official store? Thanks in advance |

So for comparison my meter looks as seen in the following pictures. Jaws are a little dirty but not scratched up. When new it the offset was a bit higher, but I've managed to magnetise it then degauss it a couple times since. Personally I would have a go at degaussing the clamp (even twirling a magnet on a stick around the jaws while moving slowly away might do the trick) and wouldn't worry about it too much as long as the offset can be zeroed out - some offset is unavoidable (e.g. mine gets about 4x worse than shown in the pic depending on orientation vs the earth). Also worth a quick check vs a normal meter. |

It's a cheap meter, and it's got a DC current range with 1mA resolution. Hall sensors are inherently quite bad at drift specifications, and added to that you also have residual magnetism and hysteresis in the clamp itself. Changes on the display when the meter is rotated are due to the earth magnetic field and this means that it's resolution is about as sensitive as you can possibly get with this class of meters. So a bit of drift for this class of meter is normal. Just be happy you've got a 2A DC current range at all. |
