This is the 3rd read on your meter. The net, or difference, between the first two (+W and –W) readings. This is your net read, and is represented as a credit or charge on your next energy statement. NOTE: These readings are cumulative, meaning they do not reset to zero after each billing period. To measure a specific time frame, check the meter at the beginning and end of the time frame you want to check. Then, subtract the readings from the end of this period from the ones observed at the starting point to get an idea of your usage.
