Use this section, not only to identify AMR or non-AMR meters, but also to
familiarize yourself with your electric meter. You will need to indentify the
spinning disc or scrolling caterpillar on your meter to do the breaker test
section coming up.
The electric meter shown to the left is an A.M.R. meter. The one to the left is a fully
electronic, digital display type of electric meter. On the old type meters that
you may be used to seeing, a revolving disc or wheel would indicate how much power
was being used. The faster the wheel spins, the more power is being used. On the
meter to the left, the disc is replaced by three black dots just under the meter
reading. This is called the caterpillar. (shown here with all three dots lit
just underneath the 6 in the reading 26840) The faster the dots go on and off
the more power is being consumed. This being the case , the dots can be used in
the breaker test to tell which breaker is making the caterpillar crawl the
fastest.
The meter
pictured to the right is the old style non A.M.R. type that must be read
visually. How would you read a meter with dials? Start at the farthest dial to
the right. That is how you read a meter with dials- from right to left.
You can see that the pointer is between 9 and 8. Always read it as the lower
number which means that the fifth digit in the meter reading here would be 8.
The next dial ( the fourth dial) would be seven. The next dial (the third) would
be 8. The next dial would be zero.( I know it looks like the pointer is sitting
directly on the 1) The last dial( actually the first dial to the left) reads 5.
It seems like it should 4 because the dial is sitting almost on top of the 5 and
the rule says always take the lower number. But in this case; because dial
number 2 has passed zero- dial number 1 would read 5. And so the reading for
this meter would be 50878. Notice the old familiar spinning disk is pointed out
here. This is very helpful in conducting the breaker test because even one light
going on and off in the house can be detected from the speed of the disk. A semi
mechanical A.M.R. (pictured below) can be read manually in the same manner or
can be read remotely.
This meter has the old familiar disk and dials
but is actually an A.M.R. What you cant see in this view is a module underneath
the meter number name plate that sends the meter reading to a remote reader.
This meter reading is 22473. Notice that this meter also has the disk that can
be utilized in the breaker test. Notice also the meter number of this
meter-90325358 . The General Electric meter above has a meter number of 73507516
.
Let's go back to reading your bill.
