I gave p ersponding to him a while back as being a useless waste of time.


Learn about reading current in a circuit.

Your little suggestion that I read the definition of the word shunt
backfired too.

Run home and cry now, little baer... errr... boy.

Ahh... so you're a double posting dope too!

This dope is still running windows 98!

BTW, I'm surprised you didn't have anything to say about my Extech/Micronta
Shootout thread? I did some resistance measurements and the Micronta is
right on with way less than 1% difference. Drifted to another plane, ha ha
ha >15 years old and still within 1% on most functions. HA HA HA HA Wrong
again DM.

How would you know without a reliable device to check it against,
dipshit?

I'll clue you... the extech ain't it.

Bwuahahahahahaahah!

Oh really? And just how do you figure that? It's brand new and it was
available with an NIST certificate (though I didn't opt for it). I guess I
need to send it to you so you can verify it against your Protek?

I told you, dumbass, I have a calibrated HP 3478A.

The protek is ANOTHER meter I have, and I use the HP to verify it.

Your NON NIST traceable and certified Extech is calibrated by an
assembler that was working enough years to end up in the production
test lab.

Their prime pass yields are likely far less than 90%, and 96% is
considered poor. Yes, you'll have to look that one up.

I'll say it again...


Bwuahahahahahahaha!

At least you didn't touch it.

Bwuahahahahahahaha!

Funny how it can be sent in and certified after the sale. I wonder how they
know who to send the good ones to. These meters you have at home, what do
you use them for? I mean I never see a schematic from you or hear of you
tinkering with some kind of experiment. Why is that?

You don't even know when you are being made fun of!

At this price and accuracy level it is almost certain that every unit
would be automatically factory tested to be in-spec, so the NIST cert
is worth the paper it's written on. You can bet the farm that
Anthony's new meter meets the published specs.

Idiot! His meter is NOT certified. Learn to read.

It comes with specs, they always apply. Wasn't it you that said that certs
were often just a check not necessarily turning screws? If the meter said
Agilent or Fluke on it, would you even be mentioning this? How come you
didn't say anything about the RMS convertor behaving the way I described? I
thought you were knowledgeable on this stuff.

Cal Certificates just state the instrument was calibrated using known
standards traceable to NIST,the date the work was done,temp and humidity
conditions,and the recommended cal interval.They may list the standards
used and their expiration dates.

Youu do realize that calibrated and certified are not the same thing, don't
you? You could have your HP 3478A certified to +/- 10% VDC.

After reading all this,I checked the $3 DMM I bought at a Harbor Freight
sidewalk sale,and it turns out the *input Z is only ONE megohm*. YUK!

My first meter cost five times that, was analog, and only had 20K ohms
per volt.

For those young folk who aren't familiar with that, yes, the meter input
impedance changed depending on the range you set the meter to.

My first meter (a cheapie my dad's friend gave me when I was about 10) was
in that range (could it have been 10k?). The better meters I had in my
younger days were a whopping 50k ohms/volt.

Check; the neatthing is that on higher voltage scales, the input
resistance exceeds that of a DMM.
Which is why i built a voltmeter/currentmeter around a 5 microamp
movement giving 200K per volt sensitivity.

I do remember seeing one of those 50K/V meters whan i was young; what
the heck has happened to them?

Mine was 2K IIRC. I still have it.
