(j) Regularly scheduled meter tests shall be in accordance with the American National Standards Institute (ANSI) Code for Electric Metering.

(k) Special meter tests: On request of a customer, the Project should within 10 days after receipt of such request, make special meter tests. The customer shall bear the cost of such tests, including meter removal and replacement when the meter is found to be within the limits of acceptable accuracy as defined in paragraphs (k) and (1) of this section. Such cost shall be a charge of $30. In all other cases, the Project will bear the cost of the test.

(1) Replacement of meter: Whenever a customer requests the replacement of the service meter because of accuracy, such request shall be treated as a request for a test of such meter and, as such, shall fall under the provision of special meter tests.

(m) Standard of meter accuracy: The Project shall not place in service, or knowingly allow to remain in service without adjustment, any meter that has known error in registration of more than plus or minus two percent at light or at full load and unity power factor, or more than plus or minus three percent at full load and fifty percent power factor.

(n) Adjustment for inaccurate meter registration: Whenever a tested meter in service is found to be fast or slow beyond the limit of accepted accuracy as defined, the Project shall make an adjustment, based on the corrected registration for the period in which the meter was registering incorrectly, if such period is known and if not known for a period of not exceeding six months, but in no event for a period longer than the present customer's occupancy. Whenever any bill or bills have been adjusted or corrected as provided above and whenever such adjustment amounts to $1 or more, the Project shall credit to the customer any amount found to have been collected in excess of the proper amount, or the Project may require the customer to pay any additional amount due, as the case may be.

(0) Incorrect meter installation: whenever any customer shall have been over-charged or under-charged as a result of incorrect installation of a meter or the use of an incorrect meter multiplier in billing the account, the

amounf of the over-charge shall be adjusted and credited to the customer, if in excess of $1 or amount of the under-charged may be adjusted and billed to the customer if in excess of $5, provided that in no event shall such period of adjustment exceed the length of time the service has been supplied to the customer through the incorrect metering installation at the present location.
