Reading a Time of Day (Day & Night) Revolving Disc Meter

Time of Day (Day & Night) Revolving Disc Meter

This meter records your day time and night time electricity usage. If you are on a Time of Day tariff, you are more likely to have this type of meter. A separate external time switch is installed to control the tariff (clock always set to GMT).

The meter may have numbers 1 and 2 or the Roman Numerals I and II against each register. On all ESB Networks’ meters, ‘1’ is your night consumption and ‘2’ is your day consumption.

How to take a reading

  • Record the number on the display from left to right on each of the registers
  • Ignore any figures in red or any figures surrounded by a red box

Safety Tip: Please be careful when reading your meter, especially if it is up high or in an inaccessible place.
