• Transparency of use
The measured value user must provide transparency for the electricity customers for
whom the devices are used by clarifying how the energy and power values which are
being billed have been obtained. "Providing transparency" means furnishing information
which will allow the electricity customers to understand how the billed items in the
electricity invoice have been calculated. The displays on the devices used for them in
conformance with statutory calibration regulations will be used for assistance here. It is
particularly important that the following information is provided:
– Which of the values displayed on the devices are actually allowed to be used for billing
purposes?
– Values which are not displayed cannot be used for billing purposes and displayed
values which are the results of functions that are not relevant to statutory calibration
regulations are purely informative in character and cannot be used for billing purposes
either.
Furthermore, the metering devices must be used such that the electricity customers are
also able to read the measurement results relevant to billing and the error messages.
• Transparency of tariffs
There are no tariffs.
• Error messages / time adjustments
– Error messages
The device function errors which the counters described here are able to diagnose and
display are described in the product description. If one or more events constituting
"error messages relevant to statutory calibration regulations" occur, use in
conformance with statutory calibration regulations is no longer guaranteed and the
stored measurement results must be regarded as unreliable. The devices must be
removed, repaired if necessary and calibrated if they are to continue to be used for
billing purposes.
– Time adjustment
In the case of counters with an internal clock that can be remotely controlled, technical
measures must be provided to ensure that displays in conformance with statutory
calibration regulations are provided on the counter to verify that the clock adjustment
which influences proper metering and billing has taken place during a billing period.
This can be achieved as follows with the counters described here: A command to
adjust the counter clock via one of the existing interfaces always results in an entry in
the calibration logbook. The current registration period at the time of the clock
adjustment is marked as invalid. The registration period which started when the time
was adjusted ends at the next whole-numbered multiple of the registration period
length (at time xx:15, 30, 45 or 00) based on the newly set counter time.
