Calibration Of Electronic Equipment In The Home Workshop

[MassiveProng]

For the moment I really think you need to avoid situations where your
'intellect' and experience could be challenged as it seems to provoke an
anger response which must be detrimental to whichever course of therapy
you are in. If you're not in therapy, you should consider it. Life's too
short to be that angry all the time.

You're an idiot. You are wrong about FPDs, you are wrong about how a
DVD player produces sound, and you are wrong about me.

Is there ANYTHING in the world that you are right about?

Your mother should be a jailed felon for not flushing your retarded
ass, the moment she shat you out of her retarded ass. You are a shit
stain on society.

 

[MassiveProng]

Now, go off, change your nym again and see how many posts you can make
before I recognize you.

You're an idiot. If I EVER wanted to be hidden, it would be no
problem, you stupid fucktard.

EVERY nym I EVER chose always held like data, so there was never an
intent to hide, you retarded ****!

It takes a true troll retard like you to act like you have some
brains, and yet prove with every post that you are more disturbed than
I could ever be.

QUOTED:
"Are you suggesting that I should drag it across town, spend $200 and be
without it for 2 weeks just to get it adjusted by some obstinate, E-1 grade
line tech, instead of using a brand new DMM w .03% accuracy to tweak it
myself? I'm quite sure that my Micronta is up to the task to be honest."

A calibration house would NOT use a 0.03% DMM to calibrate your scope
with, you pathetic piece of shit!

What part of that don't you understand?

What part of that proves that you are a brainless, pathetic piece of
shit do you not understand?

PLEASE READ MY POSTS BEFORE PISSING
YOURSELF!!!!!

**** you. I read the thread. It doesn't matter who the author is,
and when it is you, you retarded ****, it becomes glaringly obvious
due to your total stupidity. Just like the "E-1 grade tech" remark.
You prove with your every post that it is you that is an incompetent
bastard.

If you don't understand something just ask for help.

**** you. It is you that lacks the basic understanding that errors
chain together.

A .03%
METER CAN BE USED, ESPECIALLY WHEN THAT METER IS AVAILABLE WITH NIST CERTS,
NOW CAN'T IT????

NOPE.

 

[MassiveProng]

I'm not the least worried by him. He's just an interesting diversion,
provoking an anger response from him is a bit like shooting fish in a
barrel but it's starting to get boring as it's so easy and his
vocabulary is pretty small really.

You are both fucking retards. It would not, nor could not be found
to be "a threat" by any court in the land.

Grow the **** up, you retards. You two are meant for each other.

 

[MassiveProng]

Please see my earlier post regarding the use of a shunt box for a DVM.

What a joke that was. When is a 1.1M resistor EVER a current shunt?

 

[Anthony Fremont]

A calibration house would NOT use a 0.03% DMM to calibrate your scope
with, you pathetic piece of shit!

Did I say they would? I said I would tweak it myself and that it would be
good enough. Stay on track, you're here to prove why it won't work.

What part of that proves that you are a brainless, pathetic piece of
shit do you not understand?

Is that an apology? Where are your scematics and submissions?

**** you. It is you that lacks the basic understanding that errors

Show one post where I demonstrated that I don't understand that. You can't.

The problem here is that you read something and then, in your twisted little
way, you interpret it as the poster is stupid and then you go off on some
totaly different train of thought. Like Don Quixote you then procede to
fight a battle against an illusion. You then begin to see every response as
though it's calling you a liar, even if they are just trying to put you back
on track. Many of your comments were valid, but they weren't germane to the
discussion at that point, just like the one you just made here.

You make it sound like the OP was going to cal some critical lab equipment
at home and that lives were at stake. Then you go on to tout calibrating
your home theater by using a DVD/CD. And that's fine for home theater, but
for lab quality work (like you constantly brag about, and compare everything
to) considering the use of a signal from a CD is just F*CKING STUPID!!! 1Hz
accuracy would be atrocious and you know that very well.

NOPE.

Now tell us why not? Exactly what kind of standard is required to adjust
a scope's vertical response to 3% as it's specs state? And why wouldn't a
..03% meter with traceable certs be good enough? I'm not saying it isn't,
since I never even visited a cal lab, much less worked in one. I just want
to hear your expert opinion on what is required.

You need to understand the concept of ACCEPTABLE ERROR, there is no
perfection only "good enough". What is "good enough" is in the eye of the
beholder, not yours.

Tell us, oh master... what does placing a 1,1 meg resistor in
series with a circuit's power source do to the voltage presented to
the circuit?

http://www.google.com/search?hl=en&q=ohms+law

It drops it like any other shunt would. If you were designing precision
equipment, would you attempt to measure nA by using a .01Ohm resistor? Read
Ed's post, he is right about being able to measure low currents that way,
just as Robert is here. They just don't work if the current is varying over
a wide range. But for static current measurements, THEY WILL WORK FINE.

Shunt resistors are typically less than an ohm. Show me where
ANYONE uses a 1.1 meg resistor os a current shunt.

You've got to be kidding! Don't you design/build HV supplies? Tell me that
your feedback circuits sense the full output voltage. HA HA HA I guess
you don't use any micros, huh? Or do you just use a 100Ohm and .01Ohm
resistive divider to sense that 50KV output? I'd really like to see that.

 

[MassiveProng]

It drops it like any other shunt would.

Sub one ohm shunts affect the circuit very little. A fucking 1.1
meg resistor is NEVER used as a shunt resistor, and would drastically
affect ANY circuit.

How can you be so thick?

 

[MassiveProng]

Tell me that
your feedback circuits sense the full output voltage.

Voltage dividers are completely different than current shunts, you
retarded ****.

 

[MassiveProng]

You're a goddamned retard. This is about current shunts, not
voltage feedback dividers, you stupid twit!

You should go get with BAH. You are showing us that you are at her
speed.

No understanding of Ohms law wrt low currents.

No understanding of Ohms law. (now I see where Phil gets this from ;0)

 

[Jim Yanik]

LMAO!
If I use 0.5% accurate meter to adjust a something, then the accuracy
of that adjusted device at that point in time at that adjusted value
*becomes* 0.5%.

Until you turn off the "something"(DUT),the ambient temp changes,or some
hours pass(drift);then it reverts to it's specified accuracy.

4X better is the minimum for a cal standard over the DUT.
Any less has to be noted on the cal certificate.

Now tell us why not? Exactly what kind of standard is required to

0.75% or better accuracy.(4X or better)
(and that would be "adjust to within 3%". the actual result may be better
than 3%;you just can't depend on it staying that way for any length of
time.)

 

[Jim Yanik]

It drops it like any other shunt would.

all current measuring devices add resistance to the circuit,affecting it.
Just like any DMM parallels its input resistance with what it's put
across,loading the circuit under test.

If you were designing
precision equipment, would you attempt to measure nA by using a .01Ohm
resistor? Read Ed's post, he is right about being able to measure low
currents that way, just as Robert is here. They just don't work if
the current is varying over a wide range. But for static current
measurements, THEY WILL WORK FINE.

(you use the 1.1 shunt value externally because the DMMs 10 Meg parallel
resistance brings the effective R down to 1.0.)

 

[Anthony Fremont]

0.75% or better accuracy.(4X or better)
(and that would be "adjust to within 3%". the actual result may be
better than 3%;you just can't depend on it staying that way for any
length of time.)

Thanks Jim, I feel like I finally heard something I could put some stock
into. Just to set the record straight, would it be legitimate to "certify"
a device to 3% (DUT specs) using a .03% accurate DMM that has an NIST cert?
Really, it's just a matter of personal curiosity now.

 

[Too_Many_Tools]

Man does that ever sound like a personal threat.

Actually it is.

For MiniPrick aka MassiveProng to be acting this way just invites
prosecution and demonstrates how stupid this person really is. Does
anyone really believe that any professional in metrology specializing
in instrumentation calibriation would act this way? Of course not. And
would you believe any advice he might offer. Not me. I doubt he even
owns much knows how to use a multimeter.

FYI...if anyone wants to take the time to put this stupid fool in his
place, your local law enforcement will be happy to help you. One of
the interesting benefits of the Patriot Act is that they can and will
find anyone who likes to post threats on the Internet....including
Google Groups.

Now let's sit back and watch the personal attack I receive from this
clown for calling him what he is.

TMT

 

[MassiveProng]

No understanding of Ohms law wrt low currents.

Well, then you should study more.

 

[MassiveProng]

No understanding of Ohms law. (now I see where Phil gets this from ;0)

Then you should study more, dipshit.

 

[MassiveProng]

Actually it is.

No, it isn't you retarded ****.

You're an idiot, boy.

and demonstrates how stupid this person really is.

It is not a threat, dumbfuck.

Does
anyone really believe that any professional in metrology specializing
in instrumentation calibriation would act this way?

Show me where I said that, dipshit. I didn't I said that I had
worked in cal labs, and that I work in QA.

Stop making shit up, you fucking retard.

Of course not. And
would you believe any advice he might offer.

You're an idiot.

Not me. I doubt he even
owns much knows how to use a multimeter.

Far far moreso than your retarded ass does. That's why you don't
see me running around DESIGN newsgroups asking about calibration of my
instruments. If you had ANY brains at all, you wouldn't be asking
either. Then you went several steps further proving to us just how
retarded you are in subsequent posts. Good job, dipshit.

FYI...if anyone wants to take the time to put this stupid fool in his
place,

Haven't broken any laws, you retarded fuckhead.

your local law enforcement will be happy to help you.

You're an idiot.

One of
the interesting benefits of the Patriot Act is that they can and will
find anyone who likes to post threats on the Internet....including
Google Groups.

There was no threat, you retarded fuckhead. This is NOT google
groups you fucking retard. This is Usenet!

Now let's sit back and watch the personal attack I receive from this
clown for calling him what he is.

I can call you whatever I want, dumbfuck. I haven't broken any law.

So eat shit and die, you stupid ****.
