14.6 Measured Values
Metered values are system data collected and
calculated by the relay. The relay can display metered
values on the front panel LCD, or export them to a
device connected to the relay through a serial port.
The display of metered values is updated every 1 to 5
seconds. The ability to check the relay’s metered
values is helpful during commissioning, normal
operation, and troubleshooting.
5700 Operational Metered Values
5900 Thermal Overload Protection Calculated Values
Metered values are stored in these address. They are updated every 1 – 5 seconds.
