When reading your electric meter, simply write down the number the hand has passed.  Notice that some hands turn right and some turn left.

 

KILOWATT HOURS If a hand is directly on a number, you may be uncertain whether to write down that number or the next lower number. 

 meter 1

 

If the hand on the right has passed 0, write down the number to which the hand on the left is pointing.  In this case it is a 7.

 meter 2

 

In this case it is a 6, if the hand on the right has not passed 0.
