Search eBay for "panel meter"
I tried 'Centre zero', it narrows it down.
I also tried 'Center zero' and got exactly the same results.![]()
If you get an ordinary 0-1mA movement, you can adjust the hair spring to create a centre-reading pointer.
Get a $10.00 multimeter from a Chinese $2.00 shop, or from an auto shop.
I have done it may times and always got the pointer to centre-scale.
It just a matter of adjusting the hair-spring. You can desolder the end of the hair spring and reposition it on the pointer.
