If the date format setting DATE_F is set to MDY, the date is displayed as
month/day/year. If the date format setting is set to YMD, the date is displayed as
year/month/day and for DMY it is displayed as day/month/year.
To set the date (and the date format setting is MDY), type
DATE mm/dd/yyyy
and then press Enter.
To set the date for a date format setting of YMD, type
DATE yyyy/mm/dd and
then press Enter.
To set the date for a date format setting of DMY, type
DATE dd/mm/yyyy and
then press Enter.
You can separate the month, day, and year parameters with spaces, commas,
slashes, colons, or semicolons.
METER (Level 1 or 2)
The METER commands provide access to the relay metering data. The relay
divides the displayed information into two groups:
Note:
All ASCII command responses in this section are examples only. Your
specific relay has differences based on model number, firmware revision number,
and application.
•
Instantaneous
•
Thermal and RTD
METER k (Instantaneous Metering)
The METER
k command displays instantaneous magnitudes (and angles, if
applicable) of the measured and calculated analog quantities.
All angles are displayed between –180 and +180 degrees. For delta-connected
PTs, angles are referenced to VAB or L1 and for wye-connected PTs, angles are
referenced to VAN or L1.
If the voltage channels are not supported, or VAB < 13V (for delta) or
VAN < 13V (for wye), angles are referenced to L1 current.
To view the instantaneous meter values once, use the METER command (see the
example in Figure 55). To view the meter values
k
times, use the METER
k
command, where
k
is a number between 1 and 32767.
