Meter configuration properties

You can configure the meter using the configuration properties listed in this section. However, it is recommended that you use the Echelon LonMaker plug-in if you are configuring the meter using LonWorks communications.

NOTE: If Com. Protection is enabled, you may receive an error response when you try to configure the meter over communications.
