Clock-face dial meters have four, five or six dials, which alternate in direction.
To read theses meters, stand directly in front of the meter.
Starting from the right, read each dial and write down the figures.
When a dial hand points between two numbers, write down the lower of the two.
If the hand points between 0 and 1 write down 0, but if the hand points between 0 and 9, write down 9.
For example, the reading in diagram one is 2-7-0-3-8, that is, 27,038 kilowatt hours (units).


When a dial hand appears to be exactly on a number as on dial (D) in diagram two, look at dial (C) to the right. If the hand on dial (C) has not passed 0, the number 5 has not actually been reached on dial (D) and the reading on that dial is the next lower number, 4. The reading in diagram 2 is 0-4-9-8-1. That is 4,981 kilowatt hours (units).
The electro-mechanical digital display meters have a six-digit display similar to the odometer of your motor vehicle.
To read these meters you simply write down the figures that are displayed.
| 1000000 | 100000 | 1000 | 100 | 10 | 1 |
|---|---|---|---|---|---|
| 0 | 5 | 9 | 7 | 4 | 5 |
Electronic meters have a six-digit liquid display register. The register can be static or can automatically step through a sequence of displays or channels depending on the tariff for the customer. A number that appears at the top right-hand end of the register identifies each display or channel.
For those meters on a standard residential or commercial tariff (A1, L1, K1 or M1), where the registers stay static you simply write down the numbers that are displayed.
For those meters that are on Time of Use tariffs the meter register displays/channels are:
| Channel | Name / Description |
|---|---|
| 01 | Meter Code |
| 02 | Meter Serial Number |
| 03 | Programme ID Number |
| 04 | Time |
| 05 | Date |
| 06 | Kilowatt hours/Pulse |
| 07 | Total Kilowatt hours |
| 08 | Present Demand |
| 09 | Reset Number |
| 10 | On Peak Kilowatt Hours |
| 11 | On Peak Indicative Demand |
| 12 | On Peak Cumulative Demand |
| 20 | Off Peak Kilowatt Hours |
| 21 | Off Peak Indicative Demand |
| 22 | Off Peak Cumulative Demand |
| 30 | Weekdays Shoulder Kilowatt Hours |
| 40 | Weekends Shoulder Kilowatt Hours |
Customers on R1 tariff need to write down the figures from channels 10 and 20.
Customers on SM1 (Smart Power) tariff need to write down the figures from channels 10, 20, 30 and 40.
Customers on time-based Demand tariffs S1 and T1 need to record channels 10, 12, 20 and 22.
Not all channels are displayed on all meters. This depends on the tariff.
