Transformer Loss Compensation adjusts for both copper and iron losses with a simple user setup.
2.3.2: Advanced Communications and I/O Capabilities
The Nexus® 1262/1272 meter features advanced communication which utilizes multiple com ports
using open protocols. The meter's multi-port design allows multiple communication connections simul-
taneously. The Nexus® 1262/1272 system provides a direct digital link to your customer, allowing
selected data to be gathered without affecting the meter or your data. All of the advanced features of the
1262/1272 are made available through industry-standard Modbus and DNP 3.0 protocols. No propri-
etary or closed protocols are used.
