Page 3: Certificate Of Compliance
RoHS 3 compliant using exemption 6c. 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 we rely on the information provided to us by our material suppliers. -
Page 4: Introduction
This means this particular sensor should only be used for photon flux density measurements under LEDs. Apogee Instruments SQ-600 series Extended Range PFD Sensors consist of a cast acrylic diffuser (filter), photodiode, and signal processing circuitry mounted in an anodized aluminum housing. A cable to connect the sensor to a measurement device is also included. -

61 mA Calibration Traceability Apogee Instruments SQ-600 series PFD sensors are calibrated through side-by-side comparison to the mean of four transfer standard PFD sensors under a reference lamp. The transfer standard PFD sensors are recalibrated with a quartz halogen lamp traceable to the National Institute of Standards and Technology (NIST). - Page 7 Spectral Response Mean spectral response measurements of Mean spectral response measurements of six six replicate Apogee SQ-600 series Extended replicate Apogee SQ-100 (original) and SQ- Range PFD Sensors.

Page 8: Deployment And Installation
An Apogee Instruments model AL-100 leveling plate is recommended for this purpose. To facilitate mounting on a cross arm, an Apogee Instruments model AL- 120 mounting bracket is recommended. -
Page 9: Software Installation
SOFTWARE INSTALLATION The most recent version of ApogeeConnect software can be downloaded at http://www.apogeeinstruments.com/downloads/. Installing the software on a PC (Windows compatible, XP and later) 1. Double click on the installer package: 2. On the ‘Welcome’ screen, please click ‘Next’ to continue. 3. -
Page 10: Windows Software
WINDOWS SOFTWARE When the SQ-626 sensor is not plugged into the USB port, the software will display a message in the lower left corner, “Device Not Connected,” indicating it cannot establish communication with the sensor. Plug the sensor into a USB port and allow some time for the sensor to automatically establish communication with the software. - Page 11 626. The function is designed to give increased accuracy for the SQ-420. Note the ‘Immersion Setting’ function is necessary for the SQ-626. Apply an immersion effect correction factor of 1.25 to the sensor measurements when the sensor is being used to take measurements underwater.
- Page 12 After clicking the ‘Recalibate’ button the user will be prompted to cover the sensor. Place a dark cap over the sensor and wait for the real-time PFD reading to settle at zero. Click OK. Uncover the sensor and wait for the PFD reading to settle before entering the reference value.
- Page 13 These can be used to help troubleshoot if problems arise. ‘Manage Field Logging’ is used to setup the SQ-626 for use in the field. When the SQ-626 is supplied power from a USB power source (plug or select batteries) it will log data which you can retrieve.

Page 15: Mac Software
MAC SOFTWARE When the SQ-626 sensor is not plugged into the USB port, the software will display a message in the lower left corner, “Device Not Connected,” indicating it cannot establish communication with the sensor. Plug the sensor into a USB port and allow some time for the sensor to automatically establish communication with the software. - Page 16 Click the ‘Settings’ icon to display the software options. Note the ‘Light Source’ function is not necessary for the SQ-626. The SQ-626 is calibrated for use under LED light sources; therefore, this function is not necessary for the SQ-626. The function is designed to give increased accuracy for the SQ-420.
- Page 17 Clicking ‘Calibration’ will display the factory calibrated multiplier and offset values. These values are saved in firmware and can be recovered by clicking the ‘Recover Original’ button. Deriving a new calibration multiplier and offset is accomplished by clicking the ‘Recalibrate’ button. This is applicable if users want to calibrate the sensor to their own specific light source.
- Page 18 Clicking ‘Data Logging’ will allow the user to log interval measurements in a csv file while the software is open and communicating with the sensor. Click ‘Setup’ and the Setup Logging window appears. Click the ‘Browse button to create or select a csv file. Select the desired sampling interval.

3. Salt deposit accumulation from evaporation of sea spray or sprinkler irrigation water. Apogee Instruments upward-looking sensors have a domed diffuser and housing for improved self-cleaning from rainfall, but active cleaning may be necessary. Dust or organic deposits are best removed using water, or window cleaner, and a soft cloth or cotton swab. -
Page 21: Troubleshooting And Customer Support
TROUBLESHOOTING AND CUSTOMER SUPPORT Cable Length Fifteen feet is the maximum cable length that can be built into the sensor. Modifying Cable Length If you required a longer cable length an “active” USB extension cable is required. Please note, the connection between the cables must be made water tight prior to submersion. -
