Power Quality Monitoring
a
This section describes the functions of the PowerMonitor 5000 unit. Most
functions require you to configure set-up parameters to align the unit with your
installation and your application requirements. The set-up parameters are listed
by name and described in this section. You can view set-up parameters by using
the PowerMonitor 5000 web page, and when logged in to an Admin account,
make changes to the setup. Set-up parameters are also accessible by using
communication.
Please refer to the Data Tables for additional information on setup parameters
including the following:
• Range of valid values
• Default values
• Data type
Set-up parameters can be found in data tables with names beginning with
‘Configuration’, for instance Configuration.Metering_Basic.
