Default Centre zero panel meters.

Every now and again, someone asks about center zero panel meters and I've just come across them in various places like Ebay, Aliexpress etc.

They come in various sensitivities from 50uA through to 10A for about a tenner with postage. Also seen 100 & 200mV versions.

The trick to finding them in a search is to use the term 'DC Minus Zero Plus panel meter'.

Rough dimensions of 56mm high, 64mm wide and 63mm deep (yes they do protrude back a bit) - 85C1 seems to be the size category.

Mods, please move if there is a better place for this.

Hi Terry - "They come in various sensitivities from 50uA through to 10A" - do you think that is the actual sensitivity of the meter, eg 10A, or just the panel label from when originally used in equipment with the appropriate shunts etc likely to be missing now on the auction sites?

Cheers

I think the OP is asking about current production Chinese meters. These may well have internal shunts of course.

Thanks Paul, I had copied/pasted the term "DC Minus Zero Plus panel meter" into EBay and got zero hits, so was just judging by the centre zero meters I found with that simple description. I don't use AliExpress, but had a quick look anyway and saw the kind of meters that you described, one says "No need shunt" which I guess confirms that.

Cheers
Chris

As per what Paul says, I think they have internal shunts as there are higher current versions that do have external shunts shown in the listings (and at a higher cost).

Also, do not use the quote marks in the search term - just tried it on the UK site and they show up.

Terry, I see them now, but only on ebay.com, not on the UK site (ebay.co.uk)
Less than a tenner shipped, as you say, but USD so cheaper than pounds although I imagine they'll automatically add 20% VAT at the checkout.

Hi Terry - thanks for the suggestion, but I did not use the quotation marks, only copied and pasted your text within them - as evidenced by the attached screen- shot.

Cheers
Chris

Weird.

Taking the item number from one listing on the AU site and posting it in to the UK site didn't work either.

At least David found a solution to the search terms (and is what one would have expected them to be listed as).
