You are damned lucky I don't know where you are, because taking you

So you would like a judge to laugh at you too???

Tell me, what that has to do with the above??? And do you assume the neutral

You're a goddamned idiot. It goes on the neutral side. Got clue?

You're lamp cord is less safe than that.

No exposed wires on the lamp cord fool...you just separate the legs.....very
simple for most, which would certainly exclude you!
You like grasping at straws, eh?

Just stating fact drawn from your own posts here and over at alt.drugs.pot ,
where you are well known!

Sure it was....The OP'er didn't have either a meter or a clamp. So tell us
all how he would make the measurement. With your .001 ohm resistor, it would
be more expensive, with the DMM, than it would be to call a qualified
Electrician. And by the way, the electrician would be using an amp
clamp......
That was not the argument.
You don't if it only dissipates 1/4 of its rating. DOH!
Like I said, you would most likely have it dangling from a cord. Nice, real
nice. I would like to see you get UL approval on that great design!
You are an absolute idiot.

Troll #42....project your own foolishness upon the flame-ee!
Actually, I give the facts each time. You are too fucking retarded
to actually read.

Your 8 year old school yard vocabulary does not qualify as a fact....just
BlatherMatter rhetoric....yawn...same old tired crap!

This was not a post about a single PC or how to wire a branch circuit....

Oh. I thought you were trying to discuss something
relevant to this thread. Since that part of your post
was not intended to relate to the thread, that part is
irrelevant - as I stated. The RMS point, however, is
completely relevant.
Do you think your $2.99 dmm is any more accurate than the cheap amp > clamp...

I'll answer below - but since you have chosen to
go with a meter that is not capable of true RMS
readings, neither approach is acceptable.

If you read what I posted, you would have seen that
I do think it is equivalent. Its specs are better -
1.2% for the DMM, 2% for the clamp on. As shown, its
price is about one fourth of the Ebay meter you
mentioned: $2.99 vs $12.99, or $5.94 vs $22.98 when
you include shipping. To make the resistor "box"
modify a $2.88 power strip (see below - watch the line
wrap:
http://www.electronix.com/catalog/product_info.php/cPath/14_60/products_id/6919

with a precision resistor $5.01 plus (estimated)
$6.00 shipping from Mouser.
Total cost: $5.94 + 2.88 + $5.01 + $6.00 = $19.83

Show me a line of good DMM's and Amp Clamps where the clamps are more
expensive than the DMM...

A Fluke 335 (true-RMS clamp meter) lists for $194.00
at test Equipment Depot. The Fluke 110 true-RMS DMM
lists for $109 there. Same prices at Mouser. The 335
spec for the 0-400A scale is 2% +/- 5 counts. The AC
voltage spec accuracy for the 110 is 1%

As far as I know, all of them (good true-RMS amp clamps)
are more expensive than the good true-RMS DMM + precision
resistor approach for measuring PC current draw to the
same degree of accuracy. I was hoping you would correct
me on that, which was why I asked.
maybe I will learn something "in your own words"

Well, I'd be a whole bunch happier if you would
show me where I'm wrong about the price.
Also, where are you going to mount your 20 watt resistor??? Just dangle in
on a lamp cord???

Answered already. Put it in a power strip. Or use
the project box, as you suggest, or a j-box.
It's "do-able" in-line in a cord, but I would not
advise that.
Did you read the OP???

I have referred to the op many times in my
responses to you, even quoting from that post.
I'm not here to argue - your question strikes
me as having argument in mind. I'm here because
there is a disagreement in methods, and there is
always the possibility that a different method
is better than the method I have in mind. Obviously,
I believe the resistor/DMM method is better. I've
tried to make my thinking on that clear, so that you
or someone else can point out where I am wrong.
That can only help me. You have already demonstrated
that, by pointing me to a clamp-on for $23.00.
I did not know you could get one for that little.
You think you and DarkMatter are giving good advice to someone who would
even have to ask that question?

Another apparently argumentative question which
doesn't help the discussion. Can we please avoid
that? I would not knowingly post what I thought
was bad advice. So far, what I said has not been
disproved. I do not agree with using a clamp on
or DMM that does not include true-RMS capability
for this measurement. But even if you do, it costs
less with the resistor/DMM approach. That has not
been disproved - I've posted numbers and references
to support it. I've posted what you asked for - a
price comparison of good (Fluke) true-RMS meters of
both varieties - clamp on vs DMM. That is where
I hope you will prove me wrong. It's your question,
rephrased swapping clamp-ons with DMM's:

"Show me a line of good DMM's and Amp Clamps where
the" DMM's "are more expensive than the " clamp on's...

I snipped your reply so to save the NG's wheel mice since it was fairly
long....

You recommend a fluke 110 which is a bottom line fluke meter but would
probably suffice. I cannot find it for under a $109, though that is what I
found in a few moments of Googling. I have, on my bench, a true RMS Fluke 32
that I paid $69. My Google searches show it at $79 now at rapid electronics
and it is true RMS. You are correct on the fact that a true RMS may be
necesary to measure PC's. Since I have never owned anything else, I am not
sure what the error or difference would be.when measuring computer current.
I would never purchase a $3 meter for anything accept simple tasks such as
automotive etc... I would venture to guess that putting decent leads on it
would be more than the cost of the meter. This is one of those discussions
where the focus changes from the OP and centers on the example. By the
questions asked it appeared to me that the OP would not get through the
resistor/shunt method and the clamping method would be the best and the
safest. I want you to know, I was not trying to be rude or argumentative but
just had some questions. Some of which you never answered. When you jumped
in, you were siding with DarkMatter, who has a big flame going with me
currently. So, just by your comments, you somewhat became involved. You
*must* know that! Stick accross the monkeys cage?.....Ok maybe not...
One other comment. The clamp you chose was high end and the meter you chose
was not...both would have certainly worked but as far as the comparison
goes....It was only supportive of your claim and not realistic as I see it
(for what that is worth, and you may think that is zilch...and that would be
fine too)
I think I substantiated my claim here that good DMM's are more expensive
that good amp clamps......Ross : >)

DarkMatter says " I a situation where the entire premise " ....Nice Bud
Dickman....really nice!
How about the meter idiot....The OP, once again for the mentally challenged,
wanted an approximation...


You just don't get it, boy. When measuring current, the meter leads
make a difference. When measuring voltage, they do not. So to
measure voltage across a resistor is very accurate. The voltage on
said resistor will be a very accurate calculation for the current
flowing through it. Basic ohm's law.
So one more time FOOL....a cheap amp clamp and a lamp cord...

You keep bitching about safety, then, you keep removing the fault
return in the guy's circuit.

You couldn't be more retarded about electrical power.
Your suggestion of a resistor, a device to mount it and a DMM are far more
expensive and won't buy the OP single thing.

I NEVER said ANYTHING about "a device to mount it" That is ALL part
of YOUR fanatical fantasy remix of what is required. YOU are a
goddamned IDIOT that is NOT worth my time.
Talk about clueless....you have proven that repeatedly....you just refuse to

..And, you never addressed how you
intend to mount your resistor. At the .1 ohms you originally chose, 20 amps
buys you 40 watts....

Hey, retard boy. That is why I won't be using 0.1 ohm. If you had
ANY clue at all about shunt resistors, you'd know how to do this
SIMPLE, BASIC calculation.
your claim to "directly install" is ludicrous.

You're a goddamned retard, boy.
You
better mount it in something safe, 40 watts gets pretty warm....

Nobody will be dissipating 40 watts here, you retarded ****!
of course
safety never crossed your pitiful mind.....now did it?

I work around 100kV supplies. I think I got the safety thing down,
and I'll bet your investment value that you do NOT have any HV
knowledge or experience, and that you'd get your lame ass fried on day
one.

I know more about electrical safety than your lard ass ever will.
Cost never crossed your pitiful mind ...now did it? The OP's "approximate
value" requirement never crossed your pitiful mind...now did it?

The OP didn't know what he wanted. That was explained to you, but
you were too goddamned retarded to get THAT too!
Ease of
testing never crossed your pitiful mind...now did it?

Reading a shunt resistor is one of the easiest things to do in
electronics. It's right up there with reading a voltage or a
resistance value.
Therefore, like in any proof,

The only thing that you have proven is that you are a piece of shit.
100%
You are PitifulMatter !

Therefore you are retarded as I ever said you are.
You have yet to do a single fucking thing to redeem yourself from that
fact as well.

With a .001 ohm resistor you will need accuracy out to 4 places....

Wrong. One millivolt per amp... real easy. Most DMMs read at that
level without the meter being 4.5 digits in mantissa. Got clue?
and when
are you going to recommend a cheap meter to measure that?

You're an idiot.
If you don't have
4 place accuracy you will be out as much as 500ma or so on on a 5 amp
measurement.

Bullshit. A 3.5 digit meter will measure 0.04 mV, no problem. On
an
mV scale, it would read out directly in amps... no conversion needed.

0.04 would be 40mA. At 120 volts RMS, that would be 4.8 watts.
That's pretty good resolve, dipshit. Not even 1% error. Got clue?
Uhhh....that is an inaccuracy of 10%...now doesn't that take
you way out of the realm of the purpose of your resistor in the first place.

You are fucked in the head, boy. Now, shouldn't that take you the
**** away to some other newsgroup to troll?
You keep saying everyone is clueless.....look in the mirror nimrod!!!

You really should leave, and stay the **** out as well. You are

I hate to break it to you but you didn't choose the correct wattage, the .1
ohm 20 watt resistor will get hot at any current 15 amps or larger...in fact
it will fry because it should be 40 watts oh foolish one.

I hate to break it to you, retard boy, but I won't be using a .1 ohm
resistor.

The resistor chosen will be at 1/4 its rated power at max test
current.

Got clue? Grow the **** up, retard boy.
