(PBB), polybrominated diphenyls (PBDE). Further note that Apogee Instruments does not specifically run any analysis on our raw materials or end products for the presence of these substances, but rely on the information provided to us by our material suppliers.
(e.g., plant phenotyping) platforms. Apogee Instruments model SS-110 (340 to 820 nm measurement range) and SS-120 (635 to 1100 nm measurement range) spectroradiometers are small, lightweight units designed for laboratory and field use. Each spectroradiometer consists of a spectrometer (slit, diffraction grating, detector array), fiber optic, and diffuser mounted in an anodized aluminum housing.
SENSOR MODELS This manual covers Apogee model SS-110 (340 to 820 nm measurement range) and SS-120 (635 to 1100 nm measurement range) spectroradiometers. Upward-facing Sensor model number and serial number are located on the back of the sensor.
4 years against defects in materials and workmanship Irradiance Calibration Traceability Apogee SS series spectroradiometers are calibrated with a LI-COR model 1800-02 Optical Radiation Calibrator using a 200 W quartz halogen lamp. The 1800-02 and quartz halogen lamp are traceable to the National Institute of Standards and...

Maximum sensitivity of the SS-110 is near 600 nm. Sensitivity of the SS-110 is at least 10 % of the maximum value at all wavelengths greater than 380 nm.
Upward-facing: Mount the sensor to a solid surface with the nylon mounting screw provided. To accurately measure energy flux density or photon flux density incident on a horizontal surface, the sensor must be level. An Apogee Instruments model AL-200 leveling plate is recommended for this purpose. To facilitate mounting on a cross arm, an Apogee Instruments model AM-110 mounting bracket is recommended.

**Note** Windows XP users may need to install additional language options for some of the characters to display properly in Apogee Spectrovision. To do this go to Control Panel->Regional and Language Options. Click the Languages tab. In the box labeled supplemental language support, install both options. The software doesn’t care if these are installed or not; it’s simply...
OPERATION AND MEASUREMENT SS-100 series spectroradiometers have onboard circuitry which allows for output to a datalogger (via ModBus) or computer (via USB). DATALOGGER OUTPUT (VIA MODBUS) Wiring Black: Ground Red: Power (12 V) White: Receive Green: Transmit ModBus Register Layout 1-Output Mode: Digital Counts Calibrated Watts/m...

11-Starting Wavelength: Read this register to determine SS-100 Series type • Returns 340 for Visible • Returns 635 for Near Infrared 13-Power Save Mode: • Writing a 1 to this register initiates Power Save Mode (default) • Spectroradiometer is powered down between each measurement. Decreases power consumption but requires a minimum of 500 ms startup time before a measurement can be taken.
If a previously created file is chosen, the data capture function will append new data to the end of the file. A different file must be chosen for each sensor currently connected to Apogee Spectrovision. If 'Plot data to screen' is checked, the data capture function will plot the first ten measurements of the file specified during data capture setup.

These files must be saved in the correct format to be compatible with Apogee Spectrovision. Save graph as image: The current plot will be saved to an image file with the extension of your choice. Current supported extensions include *.pdf, *.jpg, *.png, *.ps, *.eps, and *.svg.

Auto-integration will max out at 2 sec. For integration times greater than 2 sec, toggle Auto-Integration off and enter the desired time in the spin ctrl box. The Apogee Visible and NIR sensors support 0.005 - 10 second integration times.

Map Color Range: Fills the area beneath the plot with the wavelength's corresponding color values. Can be toggled on or off. Keep toggled off to increase performance. This feature is disabled for multi-sensor/multi-line plots. Reset Plot: Resets the plot to original data with a generalized zoom range. Derivative data will be cleared as well.
MAINTENANCE AND RECALIBRATION MAINTENANCE Moisture or debris on the diffuser is a common cause of low readings. The sensor has a domed diffuser and housing for improved self-cleaning from rainfall, but materials can accumulate on the diffuser (e.g., dust during periods of low rainfall, salt deposits from evaporation of sea spray or sprinkler irrigation water) and partially block the optical path.
The spectrum displayed on the computer screen should now update automatically. This indicates the device is communicating with the computer and measuring a spectrum. COMPATIBLE MEASUREMENT DEVICES For use with a computer, USB 2.0 or later is required. Windows and Mac versions of Apogee Spectrovision software are available. CABLE LENGTH Maximum cable length for connection to a datalogger is 9 meters (30 feet).
RETURN AND WARRANTY POLICY RETURN POLICY Apogee Instruments will accept returns within 30 days of purchase as long as the product is in new condition (to be determined by Apogee). Returns are subject to a 10 % restocking fee WARRANTY POLICY...
