Kill A Watt comment

I sent this to the outfit that markets the KAW meter and to the
package designer:

Kill A Watt meter


I recently bought one of these meters. Nice design, provides much
information. Soon I will check its accuracy against its impressive
(0.2%) claim. Had it been in the market 6 years ago when I bought a
Brand power meter, I'd have saved over $100.

But then there is the package it came in. Over 6 times the size of
the meter, formed from 71 grams of (unmarked for recycling) probably
vinyl plastic, not particularly naturally degrading and a source of
nasty pollutants when incinerated. Tom Dolle, I hope you exercise
greater awareness in your other design projects.

I put three of them against each other (stacked) and put a unity PF load
(kettle=1500w) on them and they are read within 1 watt of each other. I was
so impressed, even though I had NBS traceable standard calibration equipment
available, I didn't bother to check them against it.

You demonstrated their consistency only. How 'bout you save me the
trouble of setting up a test and check them with that "NBS traceable
standard" gear. That would be meaningful.

And thank you for posting it.

I will try to remember to do that one day soon. Their stated accuracy is
quite impressive for a cheapo device. IIRC their stated accuracy is better
than our traceable standards...LOL

In another life I worked in the instrumentation shop of a large
manufacturer. Everything we had was NIST traceable, including test
weights and stuff.

I was fun to plug the "shop standard voltage source" into the "shop
standard voltmeter".

Also fun was to place a "shop standard weight" on a "shop standard
scale".

They never agreed completely.

Just received a unit yesterday and took it to work to test it. We have 3
meters in our lab and none are in cal so I just compared it then went and
got a caled unit 3 - 1000 watts it was within 1 watt at 1k and dead on till
about 600. It was just a quick test. I sent my bench meter to be set up and
caled and another guy said my test proved nothing and the KAW was junk.His
meter was +6 watts off at 70 and I didn't bother to check it any further my
bench unit was off -2 at 100. Tomorrow I'll raise the issue at the weekly
meeting and piss him off because he will have to red tag a bunch of test.
I'm going to order 6 more tomorrow for reference testing only and just keep
an eye on them because I don't think they can be caled. The units we use are
about 3500$ each.

Gymmie, do you ever add anything useful to a conversation? On my other
machine I had you plonked weeks ago.

Yeah, he's in my killfile as well, I don't see much point in reading whatever
it's writing.
