Each T&D Utility shall keep a complete set of records of its Meters by Customer account, including the meter type, unique meter identification code, and date of installation. The records should include all Meter repairs and upgrades, including all physical, hardware, software, or firmware repairs, modifications, upgrades, and updates, as well as all notifications or other relevant information provided by the Meter Manufacturers that could potentially affect meter registration.

The test shall be done at no charge to the Customer, provided that the Customer has not requested such a test within the past 12 months or the Meter has not otherwise been tested within the past 12 months.
b. If a Customer requests a Meter test within 12 months of the date of the most recent test of its Meter, the T&D Utility may charge the Customer for the reasonable cost of the test.
