Sorry about being off subject, but does anyone know how the power meter on a

residence could be checked for calibration?  The power company tells me not

to worry...The meter is correct...HA!

I am pretty certain that is not true.



Also I wonder if the new radio reporting meters can have their calibration

changed via radio???



Thanks for any assistance..

* Get 10 140 ohm 150W resistors

* Wire them in parallel so that you can plug them into a 120V outlet

* turn off everything in the house (Make sure the wheel below the dials

  is not moving at all.

* Plug in your resistor array.

* Wait an hour and see if the dial has moved by one kilo watt-hour.



You will be pulling about 8.5 Amps, so any 15A circuit should be OK.



Don't electrocute yourself, and remember those resistors will get HOT.

Each resistor is dissipating 100 watts.  You could also use 10 100 watt

lamps, or if you don't mind waiting longer one 100 W lamp will give you

1 KWH in 10 hours.

Turn off everything in your house (best to just open all the breakers)

and then plug in a known resistive load like a big heater into the one

circuit you leave on. Check its current draw with a clamp-on ammeter.

Measure your voltage and let the heater run for a known amount of time.

Figure watts (V*A) and multiply by time in hours. Divide by 1000 and the

result is KWH. Your meter reading and your calculations should be the same.

If you think it's not calibrated because you got an astronomically high 

electric bill last month, join the crowd.
