Essential information

Managed measurements
Introduction
WM50 calculates and displays both main line and single channel and load measurements.
All measurements are displayed by UCS or via Modbus communications (Carlo Gavazzi VMU-C monitoring system or other data acquisition system). Main line measurements are also available on screen.
Main line measurements
Note: the following values are available for all measurements: minimum, maximum, average (dmd) and maximum average (max
dmd). The available variables depend on the type of system set. Minimum and maximum values are calculated only considering
valid values and not out of range values.

Note: main line energy meter values may differ from the total
of single channel energy meters. This is because they are
measured with a different precision class (main line: class
0.5S, channels: class 2).
