[BlindHandyMan] Electric meter for outlets
Hi, We sent an old refrigerator to wherever old refrigerators go to die. As I considered trying to figure out how much electricity the old one used compared to what the new one will use I began to wonder if there's such a thing as a meter you can plug into an outlet and then plug something into the meter to find out how much electricity is being used. Is there such a thing? Ralph [Non-text portions of this message have been removed]
Re: [BlindHandyMan] Electric meter for outlets
There was a watt hour meter project in popular electronics back in the 70s I think. Sorry I can't do any better than that. I don't know how it could be adapted for the blind. It's not enough to measure the current. You need to compare the phase with the voltage to get actual power. Then it has to be accumulated over time to get total energy consumed. Regards. Max.

Re: [BlindHandyMan] Electric meter for outlets
Ralph, It would be called an A.C. amp meter and is perfectly possible, however I don't know of an off the shelf unit that will do what you want let alone one that is blind accessible. There are things called clamp amps that have a fitting that goes around a single wire from an A.C. cord, this will plug into most DMM's like the talking DMM talked about on this list. This means it is not actually electrically connected to the A.C. lines and so safer. the talking meter measures A.C. current but not to the number of amps you need for something like an appliance. I don't know why somebody doesn't make such a device, maybe they do and I just havn't seen it yet. You'd think it would be a big seller. Tom
Re: [BlindHandyMan] Electric meter for outlets
Max is, of course correct, an amp meter would give you a fair approximation but you really need a wat hour meter. I'm sure they can be bought, I'll look around, maybe there is one with a serial port to hook to a computer. Tom
RE: [BlindHandyMan] Electric meter for outlets
There are units available for $20-$40 that will give volt amp and accumulated volt amp hours on a LCD screen. Haven't seen one that gives watts and watt hours but the cheap ones can give a good comparison for what you are after. Last time I saw a good price was on newegg.com, but I have seen the same unit other places.
