Hi Folks,
I am building a new dim bulb setup. It's my second one, my bench grew a little and the current dim bulb is a little hard to safely reach.
The new one will use a little AC Voltmeter and Ammeter. Does an ac ammeter that reads 0-3amps generally have a shunt onboard or am I expected to come up with a tiny value resistor to wire in with it? There is no literature with this ammeter and nothing on the face to indicate there is a shunt onboard.
Thanks,
Dave Lowa

e.g. I have some that are electronic in nature, also some that are simple moving coil ?
The answer depends on the type you have. ?

Some information of the actual meters would be nice if you want an answer.
Sorry of course I should have included some details. This meter is a HUA SO-45. The movement, if I remember the symbols correctly , is fixed iron. I believe that's correct. It is marked "Class 2.5" and Tested to 1000V. It is an AC meter.
I'm afraid that all the information I have to offer.
Thanks for your reply.

What is "A Dim Bulb Setup"? And why measure current as part of it??
And the listing I saw in the link was a meter reading MILLIAMPS, much different from AMPS. That is to say, 1000 times less current than is being discussed.
