ISOM K-20 - 551805A - SOCOMEC

8.1.2.2. Insulation

The "Insulation Profiles" screen defines the general settings of the device:
Choosing the profile is an easy way to support the measurement algorithm on the intended application, with improved 
filtering/measurement times. 
You can choose between 3 profiles:

• Custom
• Distribution
• Control/command
