Overview
High-gain mode amplifies the incoming signal from all CTs by a factor of ten. From a practical standpoint, this means a CT with a higher amperage rating can be used to accurately measure much lower amperage. For example, with high-gain mode enabled a 100A CT could be used in place of a 10A CT.
Prerequisites
- Only available on EG4xxx or higher devices
Instructions
Step 1: Navigate to Settings → Installation from the classic interface or from the new interface Setup → Other Settings, then click Installation to the left..
Step 2: Check the ‘Use High-gain mode’ option, just above the dropdown for CT Selection.
Information
- High-gain mode requires no changes to the standard installation or wiring process. When enabled, CT amperage in the drop-down menus will decrease by a factor of ten (e.g., an 800A CT will appear as 80A). For simplicity, set the actual CT amperage first, then enable high-gain mode. This is a global setting that applies to all CTs and only affects data recorded after activation.
