There are a variety of digital meters being used today. Digital meters present a lot of data, but we are looking just for "kWh". Some digital meters record both "On-Peak" and "Off-Peak" kWh. You can eiher add the 2 numbers together or look for the "T" kWh for a total. Call your utility if you still have questions on reading your meters. Here are descriptions of typical digital meters from two utilities:
Another critical piece of information is the meter "multiplier" used with some meters. The "multiplier" is used to convert a raw meter reading to the actual kWh. Typically the multiplier is posted on the meter and on your electric bill. If your answers are not coming out right, check for a multiplier.
Most schools today use digital meters, although the older dial meters are still in use. Here is a free iPhone app used to read and calculate dial meter readings. It works by taking a picture of your meter. Good lighting helps. It's called iMeterReader.
Here's a good short video on how to read a dial meter:
Here are the steps for reading a dial meter:
Read the dials from left to right
Record the lowest reading between the numbers
If the mark is very close to the number, look to the dial to the right to help decide if the number should be the higher or lower number.
Don't forget the multiplier if your meter has one! That number converts your raw meter reading into kilo-Watt hours (kWh).
What is the correct reading be on the above meter?
