Meter features

The PM1130H / EM6438H meter supports many features, a few of the features are listed below:

LED display screen: Intuitive self-guided navigation using four buttons LED display, with three lines of concurrent values, and load bar that indicates current loading
Energy accounting and balancing
Relay (PM1130H only), alternate source, and RS-485
THD% for voltage and current, per-phase
Active, reactive, and apparent energy readings
Cyber security: The meter enables disabling the RS-485 port through front panel keys against unauthorized access. This feature can also be used for toggling between the RTU devices in case of limited availability of nodes in software system
Measurement of True PF

You can use the meter as a stand-alone device, but its extensive capabilities are fully realized when used as part of an energy management system.
