Examining Metering Quantities
Step 7. Turn the relay on.
Step 8. View metering.
a. Type ACC <Enter> to log in to the relay at Access Level 1.
b. Type the password and press <Enter>.
c. Type MET <Enter>.
The relay displays the fundamental frequency (50 Hz or 60 Hz)
metering information in a manner similar to that shown in Figure 3.29.
The metering quantities of View Metering Using the Terminal on page 3.35 are
the fundamental line quantities. Other variants of the MET command give differ-
ent relay metering quantities. See Section 8: Metering, Monitoring, and Report-
ing of the product-specific instruction manual for more information on the
specific metering options available in a specific relay.
View Metering Using QuickSet
Use the procedures in the following steps to examine the relay metering with the
QuickSet HMI.
This example assumes that you have successfully established communication
with the relay (see Making an EIA-232 Serial Port Connection on page 3.4). In
addition, you must be familiar with relay access levels and passwords (see
Changing the Default Passwords in the Terminal on page 3.10 to change the
default access level passwords). You should also be familiar with QuickSet (see
Checking Relay Status in QuickSet on page 3.12 and Section 2: PC Software).
Step 1. Start QuickSet and establish a connection with the relay. See Step 1
and Step 2 of Checking Relay Status in QuickSet on page 3.12 for
details on how to do this.
Step 2. Set the relay to a nominal operation mode. Perform the initial Global
settings relay setup of Making Initial Global Settings in QuickSet on
page 3.28 to set the relay for 60-Hz operation, ABC phase rotation.
