How to read your meter

Knowing how to read your meters can help you to keep track of your electricity consumption.

How to read your type of meter:


A dial electricity meterReading your dial meter

  1. Stand directly in front of your meter.
  2. Looking at the meter, start with the dial on your far left hand side.
  3. Read the dials in order, moving from left to right.
  4. Write down the corresponding number from left to right as you read them.
  5. When a dial hand points between numbers, write down the lower of the two numbers. For example, if it points between 5 and 6, write 5, if between 9 and 0, write 9.
  6. When a dial hand appears to be exactly on a number, look at the next dial to the right of the one you are reading. If the hand on this next dial has not passed zero (i.e. has not completed a full revolution yet), the number on the preceding dial has not actually been reached and so write down the lower number. For example, if the dial is pointing at 3, but the next dial is between 9 and 0, then write 2.
  7. Ignore any dial that does not have numbers.

A digital electricity meter

Reading your digital meter

The digital meter is simple to read. You just have to read the number that appears on the display as below for each electricity tariff that is attached to that meter.

For the most common digital or dual rate meters, the display will automatically cycle through the registers. This includes the following information:

  • 10 - Element 1 (Tariff 22 or 31 — light and power)
  • 20 - Element 2 (Tariff 41, 42, 61 or 62 if applicable — HydroHeat, hot water and/or OffPeak)

To ensure you know which tariff each element referes to, please check the back of your bill, which details your tariffs
 


A solar electricity meter

Reading your solar meter

For the most common digital or dual rate meters, the display will automatically cycle through the registers. This includes the following information:

  • 01 – Date
  • 02 – Time
  • 03 – Import to grid – Electricity you have generated back into the grid
  • 04 – Export from grid – Electricity you have bought to run light and power (Tariff 1)
  • 05 – Export from grid – Electricity you have bought to run hot water or OffPeak (Tariff 2)
  • 90 – Relay 1 status
  • 91 – Relay 2 status (if applicable)

'Import to grid' records the power flowing from the solar inverter into the grid, which occurs when there is minimal electrical consumption in the house and the solar array is producing more power than the house is using. For example, if your house is consuming 50 watts on Tariff 31 and the solar array contributes 200 watts, this register records 150 watts of power flowing from the solar inverter to the grid.

'Export from grid' register records the power flowing from the grid into the house, which occurs when there is greater electrical consumption in the house than the solar inverter is producing. For example, if your house is consuming 1000 watts on Tariff 31 and the solar array contributes only 200 watts, this register records 800 watts of power flowing from the grid to the house.

Please note scrolling between these registers does not show all the energy produced by the co-generation unit, only the power that is flowing to and from the grid.


An odometer electricity meter

Reading your odometer meter

Another kind of analogue electricity meter reads like an odometer in your car. Numbers are read from left to right.

The meter has five white digits that show the kilowatt hours of electricity that have been used.
