The Brymen 357s clamp meter is obviously not the topseller, which makes me wonder, why on earth do they put the batteries in, without knowing when the dealer will sell it?
Any manual says, that you have to take the batteries out, when not using the device for some time, but Brymen does not stick to it...even the cheapest toy has a plastic strip between the contacts!
I know, that Benning, Gossen Metrawatt, Keysight and Voltcraft put the batteries aside, whereas Fluke and Brymen put them already in - and this is the result:

The package has not been opened before - at least I think so, because of no visible signs:

I have already cleaned the reachable parts, but to do it properly, you should have to open it completely to reach any residue, which is not possible without loosing guarantee - so I will send it back...
Anyone else having this issue? Maybe with other brands?
