[1] Paragraph 5.6 (b)
substitute
(b) electricity meters installed before 1 January 2013;
(ba) electricity meters installed on or after 1 January 2013, other than electricity meters that measure less than 750 MWh of energy per year;
[2] Paragraph 5.6 (d)
substitute
(d) water meters installed on or after 1 July 2004, other than cold water meters with a maximum continuous flow rate capacity of not more than 4 000 litres per hour.

substitute
1 For in-service inspection of instruments with digital indication, add 0.5 scale interval to the maximum permissible error for in-service inspection that applies to an analog instrument.
1A However, item 1 does not apply to an instrument with digital indication if the scale interval for the instrument is less than or equal to 0.2 dm 2 .
[4] Schedule 1, Part 3, Division 6, clause 5
substitute
5 The maximum permissible error for any load equal to or greater than the minimum capacity and equal to or less than the maximum capacity in automatic operation is:
(a) if the national instrument test procedures that apply to catch weighers eliminate the need for digital rounding--the maximum permissible error set out in table 13 minus a verification scale interval of 0.5 e; or
(b) in any other case--set out in table 13.
Note The national instrument test procedures are defined in the Act and are available at www.nmi.gov.au .
