(a) Any customer may request a meter test, to determine the accuracy of his meter at any time. Such test will be made by the department, by comparison with accurate standards. The results of such tests, when requested by the customer, shall be furnished to the customer.

    (b) If any test made at the request of the customer discloses that the meter is registering correctly, or within two (2) per cent of normal, the customer shall bear the expense of such test, not to exceed sixteen dollars ($16.00) for residential meters or thirty-two dollars ($32.00) for commercial and industrial meters. The expense of all other tests shall be borne by the department.

    (c) If any meter is found to register more than two (2) per cent above or below normal, then the readings of that meter, previously taken for billing purposes, shall be corrected according to the percentage of inaccuracy found. The customer's bill shall be adjusted upward or downward as the case may be, for the corrected period.

    (d) After testing, meters shall be calibrated and restored to an accurate condition in accordance with industry standards, before being placed in service.
