Page 4: General Overview
General Overview The FIELD SCOUT CM1000 Chlorophyll Meter senses light at wavelengths of 700 nm and 840 nm to estimate the quantity of chlorophyll in leaves. ambient and reflected light at each wavelength is measured. Chlorophyll a absorbs 700 nm light and, as a result, the reflection of that wavelength from the leaf is reduced compared to the reflected 840 nm light. -
Page 5: Initial Startup
Initial Startup Allow the temperature of the CM1000 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 is first turned on, battery strength (Battery at __% ) will appear on the LCD. -
Page 6: Connecting To A Gps
Connecting to a GPS Unit The optional data logger function must be enabled using the Field Scout software in order to record a GPS signal (see Meter Settings p. 14). The GPS unit must be plugged into the CM1000 and working when the meter is first turned on. - Page 7 Cable Connections A GPS/DGPS cable (item # 2950CV5) is required to con- nect the CM 1000 meter to a GPS unit. This cable has a 9-pin male connection and a stereo pin that connects to the meter’s data port. You will also need a cable that allows the GPS unit to connect to a 9-pin male serial port.

Page 8: Keypad Operation
Keypad Operation The ON/OFF button turns the meter on and off. When the meter is turned on, ON/OFF it will display the battery status for 3 seconds. The screen will then display the amount of memory available and the status of the GPS connection. The meter then goes into normal reading mode. - Page 9 As chlorophyll measurements are taken, Data up to 99 readings are stored in the me- Recall ter’s short-term memory. These will be the readings taken since meter was turned on or the Delete/Clear Avg but- ton was pressed This is separate from the internal data logger.

Page 10: Normal Reading Mode
NOTE: Readings should be taken only on individual leaves. Canopy-level measurements are encouraged by Spectrum Technologies only for fine-textured turf grass. (See Light Management, p. 18) When in normal reading mode, the LCD of the CM1000 will display the chlorophyll index value, the brightness reading from the ambient light sensor, a running average and indicate whether the data logger is functioning. - Page 11 The response of the ambient light sensor is displayed as a brightness index value (BRT) from 0 - 9. A BRT value of one or greater indicates that there are at least 250 to 300 µmol·m ·s of PAR (photosynthetically active radiation) light available.
- Page 12 Valid INDEX readings can be taken beyond the maximum N value of 250. But N will not continue to increment unless the entire current data series is cleared, resetting N to zero. The data logger must be enabled in order to download data to a PC (See Meter Settings, p.

Page 13: Connecting To A Computer
Connecting to a Computer The data port on the underside of the CM 1000 meter can be accessed by removing the plastic screw. It is through this port that the meter is connected to either a PC or to a GPS unit. -
Page 14: Field Scout Software
Field Scout Software Meter Type The Field Scout software supports all of Spectrum Technologies’ portable data logging meters. Be sure to select the CM 1000 Meter from the Select Meter Type screen Com Port The gray software cable connects the meter to the computer data port. - Page 15 enabled by checking the first box in the Logger Settings section. If the second box in this section is checked, the logger will store GPS data only if it has been differentially corrected. If the differential correction is not found, only the chlorophyll reading will be stored in the data file.

Identifying the Correct Com Port T h e c o m p u t e r Communications Port to which the PC-3.5 serial cable is connected can be identified by using a paper clip. 1. Disconnect the serial cable from the meter. 2. -
Page 18: Light Management
Light Management Natural sunlight is the best source of light for measuring chlorophyll by reflectance because both wavelengths are present in approximately equal quantities and the quantity of light remains relatively constant. With artificial light sources, the user must be aware that different light sources emit light having different qualities. - Page 19 Canopy-level measurements recommended Spectrum Technologies for fine-textured turf grass only . When making measurements on turf grass, an adequate measuring procedure should include having the sun, the target, and the meter in approximately the same relationship with each other for each reading.

Page 23: Frequently Asked Questions
Frequently Asked Questions Why doesn’t my CM1000 detect my GPS signal? The GPS receiver must be turned on and receiving satellite signals prior to turning on the CM1000. The data output from the GPS must be specifically set for NMEA text. This setting is in the GPS receiver itself, not in the CM1000 meter or software. -
