Sec. 6.
(a) Each new watthour meter, except self-contained single phase and network meters, shall be inspected and tested and adjusted if necessary: (1) to detect any possible causes for faulty operation;(2) to verify that its register constant, test constant, gear, or dial train to be employed is correctly given;(3) to verify that the meter does not register with all load wires disconnected; and(4) to verify the accuracy of the meter. All new meters may be tested by a meter manufacturer if certified tests are supplied.
(b) All meters removed from service shall be carefully inspected for any possible causes of faulty operation that may have developed in use, cleaned and repaired, as necessary, before being tested and adjusted to the accuracy conditions prescribed in section 9 of this rule, prior to being again placed in service, except self-contained meters may be removed and reinstalled without testing if they show no damage or evidence of tampering and are not on a recall or obsolete list.(c) All watthour meters and demand meters, except self-contained meters, shall be tested prior to their installation or within sixty (60) days after installation, and adjusted, as closely as economically practicable, to the condition of zero (0) error, but in all cases within the limits of tolerance prescribed in section 9 of this rule. Such tolerances are to be interpreted as maximum variations from the condition of zero (0) error which are permitted in order to make reasonable though adequate allowance for variations encountered in accepted good meter practice.(d) All watthour and demand meters shall be checked for correct connections, proper mechanical conditions, and suitability of location in its permanent position at the time of installation or within sixty (60) days after installation. If the meter does not read directly in KWH consumed or demand units, the multiplier for the meter readings shall be checked and plainly marked on the meter, or marked on a tag attached to the meter.Indiana Utility Regulatory Commission; No. 33629: Standards of Service For Electrical Utilities Rule 6; filed Mar 10, 1976, 9:10 a.m.: Rules and Regs. 1977, p. 338; filed Feb 23, 1998, 11:30 a.m.: 21 IR 2322; readopted filed Jul 11, 2001, 4:30 p.m.: 24 IR 4233; readopted filed Apr 24, 2007, 8:21 a.m.: 20070509-IR-170070147RFA; readopted filed Aug 2, 2013, 2:16 p.m.: 20130828-IR-170130227RFAReadopted filed 4/11/2019, 9:04 a.m.: 20190508-IR-170190136RFA
