reaches a threshold value, the PPU tariff will be changed according to the
price defined for the next block. Block four has no limit. When reaching
block four the meter will continue to charge at the block four rate until a new
billing period is reached. If a threshold value is not entered then the
previous block will remain operative.
The Billing Period Usage value shall be calculated from any individual rate
register (1 to 4) or the total register.
When operating a Combination tariff the meter will take a snapshot of all
kWh registers upon reaching a Threshold Value. This will allow auditing of
the credit value applied to the meter i.e. how many units were charged at
which price.
The Billing Period is the period in days or calendar months over which the
Block Tariff is applied. In order to allow quarterly billing the Billing Period
has a configurable start date and duration. The Billing Period duration may
be configured as a number of days or calendar months. Billing periods roll-
on unless reset for COT or COS.
The Billing Period shall have duration defined in the range:
 1 to 115 days; or
 1-12 calendar months. [Start date between 1st and 28th day].
The Billing Period has a start date defined as DDMM. The Billing Period
end date is calculated as the start date plus the number of days or calendar
months of the Billing Period. Where a monthly period is applied the meter
will use the day specified in the start date as the start day of the next period
following the specified number of month's duration. The Billing Period shall
end at 24:00 on the Billing Period end date and the next Billing Period shall
start automatically.
If a billing period is specified as 3 calendar month duration starting on the
5th June the billing period would operate as follows:

On the 5th of each 3rd month the Block tariff's billing period usage value is
reset. As a result the block tariff resets and uses block 1 prices until the first
power switch threshold is reached.
