SUBMETERING. completion of any requested test, the owner shall promptly advise the tenant of the results of the test. (5) Bill adjustment due to submeter error. If any submeter is found not to be within the accuracy standards in subsection (f)(4) of this section proper correction shall be made of previous readings. An adjusted bill shall be rendered in accordance with subsection (d)(6) of this section. If a submeter is found not to register for any period, unless bypassed or tampered with, the owner may make a charge for units used, but not metered, for a period not to exceed one month based on amounts used under similar conditions during periods preceding or subsequent thereto, or during the corresponding period in previous years. (6) Bill adjustment due to conversion. If, during the 90 -day period preceding the installation of meters or submeters, an owner increases rental rates, and such increase is attributable to increased costs of electric service, then such owner shall immediately reduce the rental rate by the amount of such increase and shall refund all of the increase that has previously been collected within the 90 -day period. (7) Location of submeters. Submeters, service switches, or cut -off valves in conjunction with the submeters shall be installed in accordance with the latest edition of ANSI, Standard C12, and will be readily accessible for reading, testing, and inspection, with minimum interference and inconvenience to the tenant. (8) Submeter testing facilities and equipment. (A) Qualified expert. Each owner engaged in electric submetering shall engage an independent qualified expert to provide such instruments and other equipment and facilities as may be necessary to make the submeter tests required by this section. Such equipment and facilities shall generally conform to the ANSI, Standard C12, unless otherwise prescribed by the commission, and shall be available at all reasonable times for the inspection by its authorized representatives. (B) Portable standards. Each owner engaged in electrical submetering shall, unless specifically excused by the commission, provide or utilize a testing firm which provides portable test instruments as necessary for testing billing submeters. (C) Reference standards. Each owner shall provide or have access to suitable indicating instruments as reference standards for insuring the accuracy of shop and portable instruments used for testing billing submeters. (D) Testing of reference standards. All reference standards shall be submitted once each year or on a scheduled basis approved by the commission to a standardizing laboratory of recognized standing, for the purpose of testing and adjustment. (E) Calibration of test equipment.

Records of certifications and calibrations shall be kept on file in the office of the owner. (9) Accuracy requirements for submeters. (A) Limits.

All electrical current transformers, potential transformers, or other such devices used in conjunction with an electric submeter shall be considered part of the submeter and must also meet test calibration and phase angle limits set by the ANSI Standard C12 and the ANSI Standard C57.13 for revenue billing. A nameplate shall be attached to each transformer and shall include or refer to calibration and phase angle data and other information required by the ANSI Standard C12 and the ANSI Standard C57.13 for revenue billing.
