PSC 113.0908(2)(2) Electronic meters designed to operate over an extended voltage range may be tested at a single test voltage point to determine meter accuracy.

PSC 113.0909PSC 113.0909 Methods of testing electronic registers. Necessary tests or checks shall be made to determine that the correct program is in the meter, that the correct register is active as determined from the program, that the meter is displaying the correct date and time and that the meter’s battery mode is working and will retain register programs and recorded data during loss of power.

PSC 113.0910PSC 113.0910 Methods of testing electronic demand registers. Electronic demand registers shall be tested or checked for accuracy. The operation and accuracy of the timing circuit shall be verified. The accuracy must meet manufacturer’s published specifications. The register shall also be checked to verify that the program resets the demand period at the end of the testing demand interval.

PSC 113.0911PSC 113.0911 Testing of self-contained single-phase meters and 3-wire network meters at fixed periodic intervals. In this section, “meter” or “meters” may refer to metering system(s).

PSC 113.0911(1)(1) Self-contained single-phase meters and 3-wire network meters, together with associated equipment such as demand devices, control devices, etc., shall be tested for accuracy at unity power factor at the point where they are installed or at a central testing point or in a mobile testing laboratory under any of the following circumstances:

PSC 113.0911(1)(a)(a) Before being placed in service. For new meters given a prior test by the manufacturer, a sample test program meeting the requirements of s. PSC 113.0920 or use of the manufacturer’s certified test results for all meters tested under the provisions of s. PSC 113.0921, may be substituted for this requirement.

PSC 113.0911(1)(c)(c) When the accuracy is questioned by a customer. See s. PSC 113.0922.

PSC 113.0911(1)(e)(e) Within a period of 6 months before to 6 months after 5 years of service for non-magnetic-bearing meters and 20 years of service for magnetic-bearing surge-proof meters or in accordance with the plan outlined in s. PSC 113.0921.

PSC 113.0912PSC 113.0912 Testing of self-contained polyphase meters. In this section, “meter” or “meters” may refer to metering system(s).

PSC 113.0912(1)(1) Self-contained polyphase meters together with associated equipment such as demand equipment, control devices, etc., shall be tested on the customer’s premises, a central testing facility or in a mobile test facility, except pars. (a) and (d), for accuracy at unity and 50% power factor under the following circumstances:

PSC 113.0912(1)(a)(a) Before being placed in service. For new meters given a prior test by the manufacturer, the manufacturer’s certified test results may be substituted for this requirement.

PSC 113.0912(1)(c)(c) When the accuracy is questioned by a customer. (See s. PSC 113.0922.)

PSC 113.0912(1)(e)(e) Within a period of 6 months before or 6 months after 8 years of service for non-surge-proof and 12 years for surge-proof meters. Exception: Thermal and mechanical lagged-demand meters shall be tested every 8 years. Electronic (solid state) meters may be tested instead in accordance with the plan outlined in s. PSC 113.0921.

PSC 113.0912(2)(2) A stator balance test shall be performed on all new meters before being placed in service.

PSC 113.0912(3)(3) Meters with electronic programmable registers may be shop tested on a periodic basis.
