Subject: Re: old analog meters

Post:







I'm always on the hunt for simpson and similar brand
3" or larger analog meters. Especially if they are in the
following ranges:

DC Ammeters
100 mA
300 mA
500 mA
1 A
10A

DC Voltmeters
5V
10V
25V

We really emphasize the difference in how the meters are connected
in the labs. They work well and save the frustration of explaining
what the other ten positions on the multimeter dial are about (we
do get to that but not 'til much later in the course).

By the way, I have a nice ammeter protection circuit our
electronics guru designed to elliminate blown fuses. If anyone is
interested I'll try and remember to bring one to the summer
meeting. It's pretty neat.
