Initial Tests
Section 460
Section 460.390 Initial
Tests
Initial tests are tests made
before installation, regardless of whether the meter and associated devices
have previously been in service. Each meter and associated devices (unless
included in the sample testing plan in Section 460.410) shall be inspected and
tested in the meter shop of the MSP or other location that meets the
requirements of this Part before being placed in service, and the accuracy of
the meter shall be within the tolerances permitted by this Part. If a meter is
removed from a customer's premises, except for field testing, it shall be
tested and inspected as described above before it is placed in service again.
If creep or inaccuracy is discovered in a meter removed from service, the MSP
shall correct the metering data as detailed in Section 460.440.
