It registers 10,000kilowatt-hours. While the first, the one on the extremeright, makes one complete revolution, the one next to it ispassing from one numberto the next and while thatone is making a completerevolution, the one nextto it is passing from onenumber to the next, etc. The 10 pointer will haveto revolve 10 times whilethe 100 pointer is revolv-ing once, and the 100pointer will have to make 10 complete revolutions beforethe 1,000 completes one revolution. A little study willshow, then, that in reading the meter it is possible tostart at the left and read the smaller numbers on thefour dials (Fig. 59). This is a general rule to follow,
