To measure the current of an HVAC condenser fan motor, I used an old
Simpson analog shunt (non clamp-on) meter.
Assuming that the meter is operating as designed, is there any reason
why this meter would not give a correct reading?
Assuming the motor is powered directly from a sinusoidal line source and
not from some undefined exotic solid state speed controller, the answer
to your question is yes.
Amps are amps. Reactive current comes into play when you are figuring
real and imaginary power.
I inheritred this meter from my father-in-law who repaired air
The 0-30 Amp meter is built into a box with a receptacle cord on one
end and a plug on the other.
You plug it in and then plug you appliance in to measure its current
Thanks for you ample advice!

I remember using a 'wiggy' way back when. It had a slot to hold one
probe and it was fine for testing for voltages. Is that what you call
a 'wiggy' or are you referring to a low impedence multimeter pre-vtvm?
Stu posts questions, baiting everybody. Then we try at first to answer him.
Our answers are not to his liking, so he posts his questions differently in
a science forum. the answers he gets there he confronts us with, telling us
we know nothing. He has an agenda to tell everybody he is doing the correct
thing by running his motor at half voltage and he is absolutely safe in
doing so. Stu, many people have survived going over Niagara Falls in a
barrel even when they were told they might die. Try it, you won't
necessarily get killed, but if you do, we can read about your braveness and
say: "what a jerk", "he had to prove us wrong". If you survive, we can say
"what a jerk"
So stu, if you can read this: I am a scientist. everything I said to before
you is fact. everything you were told by others here is also.
My analysis of you Stu, is that you are a stupid fucking asshole; it is my
opinion. Ask the science people if they think you are an asshole; I bet they
tell you that you are too. Now, assholes DO have a purpose in life, so
scientifically you are a misfit. Maybe you are supposed to be a mouth and
your genes got crossed; ask the scientists. In any case, you are obnoxious,
which is one of the definitions of asshole. And don't forget, I stayed in a
Holiday Inn express last night again, so I am really smart, and my company
saved big bucks on that.
want to check my credentials? call 1-800- eat-shit; ask for iggy-not-ziggy.
ask them about your project. You are a perfect subject for Ted Danza's new
I won't be able to directly read your reply if you choose to do so here,
stu, but I am sure some kind sole will include it in something they write.
