- Page 3 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 rely on the information provided to us by our material suppliers.
- Page 4 This means this particular sensor should only be used for photon flux density measurements under LEDs. Apogee Instruments MQ-620 meters consist of a handheld meter and a dedicated sensor that is connected by cable to an anodized aluminum housing. SQ-600 series Extended Range PFD Sensors consist of a cast acrylic diffuser (filter), photodiode, signal processing circuitry mounted in an anodized aluminum housing, and are potted solid with no internal air space.
- Page 5 Apogee MQ series quantum meters covered in this manual are self-contained and come complete with handheld meter and sensor. Sensor model number and serial number are located on a label on the backside of the handheld meter.
- Page 6 4 years against defects in materials and workmanship Calibration Traceability Apogee MQ series quantum meters are calibrated through side-by-side comparison to the mean of four transfer standard quantum sensors under a reference lamp. The reference quantum sensors are recalibrated with a 200 W...
- Page 7 Directional, or cosine, response is defined as the measurement error at a specific angle of radiation incidence. Error for Apogee SQ-600 series Extended Range PFD Sensor is approximately ± 2 % and ± 5 % at solar zenith angles of 45° and 75°, respectively.
- Page 8 Apogee MQ series quantum meters are designed for spot-check measurements, and calculation of daily light integral (DLI; total number of photons incident on a planar surface over the course of a day) through the built-in logging feature. To accurately measure PFD incident on a horizontal surface, the sensor must be level. For this purpose, each MQ model comes with a different option for mounting the sensor to a horizontal plane.
- Page 9 MQ series quantum meters are designed with a user-friendly interface allowing quick and easy measurements. To power the meter, slide the included battery (CR2320) into the battery holder, after removing the battery door from the meter’s back panel. The positive side (designated by a “+” sign) should be facing out from the meter circuit board.
- Page 10 Downloading the stored measurements will require the AC-100 communication cable and software (sold separately). The meter outputs data using the UART protocol and requires the AC-100 to convert from UART to USB, so standard USB cables will not work. Set up instructions and software can be downloaded from the Apogee website (http://www.apogeeinstruments.com/ac-100-communcation-cable/).
- Page 11 Although Apogee sensors are very stable, nominal accuracy drift is normal for all research-grade sensors. To ensure maximum accuracy, we generally recommend sensors are sent in for recalibration every two years, although you can often wait longer according to your particular tolerances.
- Page 12 Verify Functionality Pressing the power button should activate the LCD and provide a real-time PPFD reading. Direct the sensor head toward a light source and verify the PPFD reading responds. Increase and decrease the distance from the sensor to the light source to verify that the reading changes proportionally (decreasing PPFD with increasing distance and increasing PPFD with decreasing distance).
