READING THE ELECTRIC METER
There is no question but what electricity is one of the lowest cost
services in the home and on the farm. A few pennies worth of electricity
will provide the power to run machines that take the place of a man or
of several men working all day. However, we all like to know what things
cost.
Sometime you may have to decide between different methods--man, horse,
gasoline engine or electric motor power. Then you'll want to know how to
figure the cost of electricity, as well as the cost of the original
equipment. First of all, you should know how to read an electric meter.
Reading a Meter
Electric meters read in kilowatt hours, just as a water meter reads in
gallons and a gas meter in cubic feet. A kilowatt hour is the electrical
energy consumed by 1000 watts of electricity used for one hour. Ten
100-watt light bulbs burning for one hour would use one
kilowatt-hour--one kwh.
[Illustration: Figure 1. Some meters give the reading directly, like the
mileage total on a speedometer.]
Some meters are read directly, as shown in Figure 1. The more common
type has four dials which are read from right to left--just the opposite
from the way things are usually read. The hand on the extreme right
turns clockwise, the next hand turns counter-clockwise, the next
clockwise; the last hand on the left turns counter-clockwise.
The first dial on the right can register up to 10 kilowatt-hours; the
second up to 100 kwh; the third, to 1000 kwh; the fourth, to 10,000 kwh.
After that, the meter starts over again. To take a reading you must read
all four dials of the meter, from right to left.
