Adjustment of bill when meter inaccurate.

1. If a meter is tested pursuant to NAC 704.343 and is found to be inaccurate by more than 2 percent, the bill for service of any customer affected must be adjusted as provided in this section. 2. Except as otherwise provided in subsection 3, if the meter has: (a) Under-recorded the usage of gas or electric energy, the adjustment must be made only for the period of the most recent 3 months of usage. (b) Over-recorded usage, the adjustment must be made only for the period of the most recent 6 months of usage. 3. If the utility establishes that the meter has been tampered with or used without its authorization, the adjustment must be calculated for a period not to exceed the most recent 6 months of usage or the date on which the tampering or unauthorized use began, whichever is greater. 4. A customer who, because of an adjustment to his or her bill, owes the utility money for service may pay that amount over a 3-month period. 5. The utility shall credit the account of a customer who was overcharged because of an inaccurate meter not later than 30 days after the overcharge is determined.
