a
Devices used for power quality monitoring, when they provide active energy measurement function, can be
used for energy usage analysis.
b
Devices used for power quality monitoring in accordance with IEC 62586-1 can be used for power monitoring
especially where comparable measurements are needed.
NOTE Other information such as occupancy, number of operations, manufacturing figures, is provided by
different instruments and are covered by other standards.

8.3.1.3 Measurement
Replace, in the 3 dashed list items, in the third paragraph, "PMD-1", "PMD-2" and "PMD-3"
with "PMD-I", "PMD-II" and "PMD-III" respectively.
