Command Description
MET AMV
The MET AMV command lists automation math variables.
The relay displays three places after the decimal point for these numerals. The
relay shows variables with absolute value greater than 99999.999 or less than
0.100 as scientific notation (for example, –1.002E+22).
MET ANA
Use the MET ANA command to view the analog quantities from the MIRRORED
B
ITS communications channels.
If you have not enabled the MIRRORED BITS communications channels and the
remote analog data, the relay response to this command will not include any val-
ues. If M
IRRORED BITS communications is enabled but not communicating, the
relay will display
ERROR under the RMBA or RMBB entries, depending on settings.
MET BAT
Use the MET BAT command to view the station dc monitor quantities for the
battery voltages.
NOTE: Some relays provide one
battery monitor channel and some
support two.
If you have not enabled the Station DC Battery Monitor, the relay responds with
DC Monitor Is Not Enabled. (Enable the dc monitor with the Global setting
EDCMON.)
The reset command, MET RBM, resets the dc monitor maximum/minimum
metering quantities. When you issue the MET RBM command, the relay
responds with
Reset Max/Min Battery Metering (Y/N)?. If you answer Y
<Enter>, the relay responds,
Max/Min Battery Reset.
