Allow the temperature of the CM1000 NDVI meter to
equilibrate with the plant environment prior to sampling.
For example, storing the meter overnight in a freezing tool
shed and then immediately taking readings upon entry into
a warm greenhouse will result in invalid data.
When the CM1000 NDVI meter is first turned on, battery
strength (
Battery at __%
) will appear on the LCD. The
available battery power percentage assumes alkaline
batteries are being used. If rechargeable NiCd batteries
are installed, the available battery power will be less than
displayed. If the data logging option has not been
enabled, the unit will then proceed to the normal reading
mode.
In order to record data and global positioning system
(GPS) coordinates, the data logger must first be enabled
through the software (See p. 13). If the data logger has
been enabled, battery strength and the amount of
remaining memory (
Memory __ % FULL
) will be
displayed. If GPS data is being recorded as well, the
meter will display the status of the GPS signal. The meter
will then proceed to the normal reading mode.
IMPORTANT:
The
GPS
unit must be powered up,
have located the satellites and been connected to the meter
before turning the meter on (see Connecting to GPS Unit
p. 5).
