On the face of most electric meters are four to five numbered dials, with each dial
moving in an alternate direction. The numbers on these dials, when read as a unit
(not added together) show your on-going electrical usage measured in kilowatt-hours.
If you subtract the prior meter read (let's say 10627) from your current meter
read (10889), you will find that you have consumed 262 kilowatt-hours of electrical
energy.
But what if the pointer is between numbers? The correct number to use in
your reading is always the last number the pointer has passed.
