Parameter Value Description
Time Sync
Source
COM1, COM4,
ETHERNET,
ETHERNET - ION,
ETHERNET - DNP,
ETHERNET - PTP,
IRIG-B
Sets which device port accepts time
synchronization messages.
Time synchronization messages on other ports
are ignored.
For GPS time synchronization, set the Time
Sync Source to COM1 (or COM4).
For SNTP/NTP time synchronization, set the
Time Sync Source to ETHERNET.
For ION time synchronization, set the Time
Sync Source to ETHERNET - ION.
For DNP time synchronization, set the Time
Sync Source to ETHERNET - DNP.
For PTP time synchronization, set the Time
Sync Source to ETHERNET - PTP.
For IRIG-B time synchronization, set the Time
Sync Source to IRIG-B.
Clock
Source
Internal, COMM, Line
Freq
Sets the source for the clock:
Internal: the meter’s internal clock.
COMM: the meter’s communication port
(used by the IRIG-B, GPS or ETHERNET -
PTP time sync source).
Line Freq: uses the measured line frequency
of the power system as the clock source.
DST Offset
Numeric Bounded
Format/Elapsed Interval
Format
Specifies the amount of time the displayed local
time is moved forward when entering Daylight
Savings. A value of zero disables this feature and
local time is not adjusted for DST.
Start of the
Week
Monday–Sunday
Specifies the start day of the week used for
Trending and Forecasting.
NOTE: Changing the start day of the week clears
all trending and forecasting data.
