EcoRenovator - View Single Post - Itron Centron Watt-Hour Meter, Read real-time use, yourself

I found this info here:
Reading your Itron Centron C1SR Digital Electric Meter - The Watt emulator

Underneath the right-hand LCD digit, there are three little squares.
(To the right of kWh)

"Here is the pattern. First the left goes on, then the middle goes on,
then the right goes on, then the left goes off, then the middle goes off,
then the right goes off. Kind of like a digital wheel being emulated, cute.
Well, that full cycle is 6 watt-hours or to make it simpler,
every time one of those dots changes it is 1 watt-hour.
Now you can do simple tests of turning on something (like a hot tub,
hair drying, drier, tv, light bulb, etc) and count the number of dots
you see or if it is going fast the number of cycles (multiple by 6 the result)
and you have the energy usage of watt-hours of that appliance during a fixed period."

~~~
Anyways, I took out my stopwatch and set it to beep after 60 seconds.
At the beginning of a cycle, I hit the Start button and counted the cycles (or dot changes)
until I hear the beep.

By knowing the number of watt-hours in one minute, I multiplied my count
by 60 to get the watt-hours in one hour. If I counted 24 LCD changes,
24x60=1440Wh, or 1.44 kWh.. In my case, 28.8 cents an hour..

Cheers,
Rich
