The department, at its own expense, will make periodical tests and inspections of its meters in order to maintain a high standard of accuracy of said meters. The department will make additional tests or inspections of its meters at the request of the customer. If tests made at a customer's request show that the meter is accurate within three percent (3%), either slow or fast, no adjustment will be made in the customer's bill, and the testing charge of ten dollars ($10.00) per meter will be paid by the customer, said amount to be included in the next bill sent to the customer by the department. In case the test shows the meter to be in excess of three percent (3%), either slow or fast, an adjustment shall be made in the customer's bill over a period of not to exceed thirty (30) days prior to the date of such test, and cost of making the test shall be borne by the department.
