Re: Analog meters
Thanks for the correction, I did not mean to misinform you!
When I die, I want to go like my Grandfather did, peacefully in his sleep.
Not screaming like the passengers in his car!
Cutting out a man's tongue does not mean he’s a liar, but it does show that you fear the truth he might speak about you!

Re: Analog meters
There are several ways to make an AC meter without rectification. One method I found replaces the permanent magnets found in common D'Arsonval movements to electromagnets. When the current switches direction, all magnets change polarity, so needle moves in only one direction.tsutt wrote:Robert would you like to explain. its a one direction meter. its says FS - 10 rect. on the box. and its old its a honeywell model 45t. i tried to look it up but didnt find any thing.
I googled 'ac galvanometer without rectifier', or something like that. The point is, using a bridge rectifier isn't the only way to make an AC ammeter.
However, now you mention the word rect. is on the box... I won't guess what it actually is. I'd experiment with feeding it a small DC current, and see what happens.
