The optional data logger function must be enabled using
the Field Scout software in order to record a GPS signal
(see Meter Settings p. 13).
The GPS unit must be plugged into the CM1000 NDVI
meter and working when the meter is first turned on. If a
GPS signal is found at startup, the logger will search for a
GPS signal for every reading. If no GPS signal is found
when the meter is first turned on, the meter will not search
for one when taking readings, thereby saving time when
taking readings. In this case the LCD will display the
No
GPS Found
message.
For each reading,
GPS
will be displayed on the bottom
right of the screen. If the GPS signal is lost during a
series of readings, or if the specified differential correction
is lost, the LCD will display
LOG
rather than
GPS
in the
lower right corner of the screen. During subsequent
readings, the meter will again search for a GPS signal and
upon finding one, will again display
GPS
.

messages. If the meter has trouble receiving the GPS
signal, check that the GPS unit has the following settings:
Data bits: 8
Stop bits: 1
