(a)	The method for calculating the overall error is the vector sum of the errors of each component part (that is, a + b + c) where:
a = the error of the voltage transformer and wiring;
b = the error of the current transformer and wiring; and
c = the error of the meter.
(b)	If compensation is carried out then the resultant metering data error shall be as close as practicable to zero.

(c)	Where the check metering installation duplicates the metering installation and accuracy level, the average of the two validated data sets will be used to determine the energy measurement.
(d)	Partial check metering involves the use of other metering data or operational data available to AEMO in 30 min electronic format as part of a validation process in accordance with the metrology procedure.
(e)	The physical arrangement of partial check metering shall be agreed between the responsible person and AEMO.
