MET Command (Metering Data)
The MET command (see Table 7.28, Ta ble 7 .29 , and Table 7.30) provides
access to the relay metering data.
For more information on metering and example responses for each meter
class, see Section 5: Metering and Monitoring.
On issuing the MET c R command for resetting metering quantities in class c,
the relay responds:
Reset Metering Quantities (Y,N)? Upon confirming
(pressing Y), the metering quantities will be reset and the relay responds with
Reset Complete.
