Transmissions and Measurements Coinciding
Make sure to have the transmission scheduled a short while
after
the
measurements are completed. If the measurements happen at the 15-minute
mark, set the
transmission time
to 16 minutes to ensure the measurements are
completed
before the transmission process starts.
If the transmission coincides with the start of measurement collection, chances
are that the most recent measurements will not complete before the
transmission process starts. This will mean that the transmission will contain
missing data!
For example, if the station is set up to sample an SDI-12 sensor every 15 minutes
and transmissions are set up to go once an hour, unless the
Tx Time
is changed
from 00:00:00, only three readings will appear in the transmission. The
Tx Time
must be changed to allow for the measurement to
complete
. If the SDI-12
reading takes 30 seconds, set the
Tx Time
to 00:01:00 to ensure ample time for
the measurement to complete before transmissions are started.
