tab, set
Clock sync (PTP)
to
Automatic
and the
time/location will be updated when the data is received from satellites. When using
PTP, the Date and Time fields are populated automatically. PTP will override any
settings you enter in those fields.
Important: In order to synchronize instrument clocks with GPS satellites
through the SmartFlux 2 System, PTP (Precision Time Protocol) must be
enabled and set to
Automatic
.
When configuring indoors, GPS/PTP might not take effect right away. When no or
few satellites are visible, time-keeping for your eddy covariance system will nor-
mally revert to the gas analyzer clock.
Time Zone:
Select your EC station's time zone from the dropdown list. If the loc-
ation observes daylight savings time, you should choose an offset from etc/GMT in
order to avoid overwriting or creating duplicate files during a switch between stand-
ard time and daylight savings time.
Important: etc/GMT offset is the number of hours added to or subtracted from
your local standard (non-daylight savings) time in order to equal GMT. For
example, Lincoln Nebraska is in Central Standard Time, 6 hours behind GMT
(when daylight savings is not in effect), so you would choose
etc/GMT+6
from
the dropdown list. This is different from the usual GMT offset convention which
would use -6.
While the settings are open, click the
Advanced
tab and check the chopper hous-
