measuring ampermeter meter internal resistance

want to shunt a multimeter to extend it's ac ampermeter range so
measured with Rish 14s in ohm meter position about 41 ohms
and then measured with Rish 14s its own internal resistance to get 40
ohms
Is this way to much -there is some mistake?
(http://www.multimetercalibrationsaustralia.com.au/rishmulti14s.pdf
but cannot find data about it's internal resistance!)

No Stupid, that's not the way to ampmeter range to higher range. Why did
you call yourself Superpower Punk? You don't even know how to multiple the
power of your electronic? You see, I am a superdumb-ass and I am very
capable to multiple current as well as AmpMeter by 10X.

Sadly those who do it, rarely care about laws or crime... What's funny
is that the poster is easily traceable. He should have used an
anymonous remailer like the others do. (Then he'd be blocked by our

Thanks for that, and now that I have Mr. I'm-not-all-that-bright's ISP
listed on the header he forged _and_ his real-world name and address
it shouldn't be long before he'll be thinking every little sound he
hears is the NYPD knocking on his door. :)

So good so far.

According to the link the voltage drop is 270 mV at 10 A current.
This should not be hard to calculate the internal resistor of the
multimeter based of this information :)

in ohm meter position about 41 ohms
and then measured with Rish 14s its own internal resistance to get 40
ohms
Is this way to much -there is some mistake?

Those values do not make any sense for any realistic current meter
(except for some extremely low current applications).

For your own safety, if the 10 Aac current range of the multimeter is
not enough, please consider using a current transformer for measuring
large 50/60 Hz currents.

And remember that with current transformers, the secondary must
_always_ be shorted or connected to a low impedance meter.

Oh my Gosh, you are really Stupid. Stop using internal resistance to expand
Amp meter Dumbass. It's not the way to do it fucker.

Your 0.270a to overcomde the accurancy of 10A? No wonder why you are too
Superdumb.

If you do the right thing, you can turn a 10A meter into 100A meter with
0.02% error.

Why should I tell you Superpower? You should know it if you are really what
you believe you are. Ok numbass?
