5.10.1 Deviation Standards (Digital Operation)

The specifications in this table allow a spread of ± 10%. However, the accuracy of the service monitor
needs to be taken into account. Since the accuracy of the service monitor is only ± 5%, the allowable
spread in the measured deviation should only be ± 5% and not ± 10%.
