SECTION 165:35-15-13. Accuracy requirements for demand meters

(a)   Acceptable performance. The performance of a demand meter or register shall be acceptable when the error in registration does not exceed four percent (4%) in terms of full scale value when tested at any point between twenty-five percent (25%) and one hundred percent (100%) of full scale value.

(b)   Adjustment limits.

(1)   When a demand meter or register indicates that the error in registration exceeds ± four percent (4%) in terms of full scale value, the demand meter or register shall be adjusted to within ± two percent (2%) full scale value.

(2)   The timing element when used to keep a record of time of day at which the demand occurs, shall be adjusted to a condition of as near zero error as practicable when it is found to be in error by more than ± 0.25 percent.
