I just thought I would share something. I found these on ebay a while back and ordered 1 not expecting it to be much.
But it is a very clear easy to read meter that you can enclose in a small case or whatever and use.
I am planning to solder some leads to it and put it in a small box,like a Tic Tac candy container just to have handy when testing voltage on something. No load test obviously but handy to know if anything is there at all.
Here is a pic of mine beside a pencil for size.
Less than a dollar free shipping and it comes packed well.
