I tried 'Centre zero', it narrows it down.Search eBay for "panel meter"
The problem is that there are some zero center meters in the "panel meter" category whose sellers haven't used the words "zero center" in the description, so a search won't find those.I tried 'Centre zero', it narrows it down.
I also tried 'Center zero' and got exactly the same results.![]()
I've tried that already. No way to get the needle centered. (max. 1/3 of the scale)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.
Thanks for the advise. I better forget about the analogue voltmeter, since the customer has decided to use two LED bar graphs instead.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.
