Page 5: Introduction
Note: The handheld meter is not waterproof, only the sensor and cable are waterproof. MQ-210X meters consist of a handheld meter and a dedicated quantum sensor that is connected by cable to an anodized aluminum housing. Sensors consist of a cast acrylic diffuser (filter), photodiode, and are potted solid with no internal air space. -
Page 6: Sensor Models
SENSOR MODELS Apogee MQX series quantum meters covered in this manual are self-contained and come complete with handheld meter and sensor. A sensor’s model number and serial number are located on a label on the backside of the handheld meter. -

SPECIFICATIONS MQ-210X Calibration ± 5 % (see calibration Traceability below) Uncertainty Measurement Less than 1 % Repeatability Long-term Drift Less than 2 % per year (Non-stability) Non-linearity Less than 1 % (up to 4000 µmol m Response Time Less than 1 ms Field of View 180°... - Page 8 Spectral Response Mean spectral response of four MQ-210x series quantum sensors compared to PPFD weighting function. Spectral response measurements were made at 10 nm increments across a wavelength range of 350 to 800 nm in a monochromator with an attached electric light source. Measured...
- Page 9 Cosine Response Directional, or cosine, response is defined as the measurement error at a specific angle of radiation incidence. Error for Apogee MQ-100X series quantum sensors is approximately ± 2 % and ± 5 % at solar zenith angles of 45° and 75°, respectively. Mean cosine response of five MQ- 100X series quantum meters.

Page 10: Deployment And Installation
To accurately measure PFFD incident on a horizontal surface, the sensor must be level. The AL-100 accessory leveling plate is recommended for use with the MQ-210X to ensure the sensor is level when attached to a cross-arm. The bubble-level in the plate makes leveling simple and accurate. -
Page 11: Battery Installation And Replacement
BATTERY INSTALLATION AND REPLACEMENT Use a Phillips head screwdriver to remove the screw from the battery cover. Remove the battery cover by slightly lifting and sliding the outer edge of the cover away from the meter. To power the meter, slide the included battery (CR2320) into the battery holder, after removing the battery door from the meter’s back panel. -
Page 12: Operation And Measurement
OPERATION AND MEASUREMENT MQX 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 13 Reset: To reset the meter, in either SMPL or LOG mode, push the mode button three times (RUN should be blinking), then while pressing the down button, press the mode button once. This will erase all of the saved measurements in memory, but only for the selected mode. That is, performing a reset when in SMPL mode will only erase the manual measurements and performing a reset when in LOG mode will only erase the automatic measurements.
- Page 14 The MQ-210X sensor has an immersion effect correction factor of 1.15. The immersion effect correction factor is already accounted for in the MQ-210X meter firmware so there is no need to apply the correction factor to your measurements. If you wish to use your meter to make measurements in air, simply divide the measured number by the immersion effect (1.15).

Page 15: Apogee Ams Software
APOGEE AMS SOFTWARE Downloading data to a computer requires the AC-100 communication cable and the free ApogeeAMS software. 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. The most recent version of ApogeeAMS software can be downloaded at http://www.apogeeinstruments.com/downloads/. - Page 16 “Daily Totals” shows all of the saved Daily Light Integral (DLI) totals per day. Click “30 Min Avg” to see the meter’s 99, 30-minute averages. To analyze the data, click on “File” and “Save As” to save the data as a .csv file. Or, you can highlight the numbers, copy, and paste them into a blank Excel spreadsheet.

Page 17: Maintenance And Recalibration
MAINTENANCE AND RECALIBRATION 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. - Page 18 Homepage of the Clear Sky Calculator. Two calculators are available: one for quantum sensors (PPFD) and one for pyranometers (total shortwave radiation). Clear Sky Calculator for quantum sensors. Site data are input in blue cells in middle of page and an estimate of PPFD is returned on right-hand side of page.

Page 19: Troubleshooting And Customer Support
TROUBLESHOOTING AND CUSTOMER SUPPORT 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). - Page 20 Error Codes and Fixes Error codes will appear in place of the real-time reading on the LCD display and will continue to flash until the problem is corrected. Contact Apogee if the following fixes do not rectify the problem. Err 1: battery voltage out of range. Fix: replace CR2320 battery and perform master reset. Err 2: sensor voltage out of range.
