Auto Calibration Function for CO2 Sensor

What is “Auto Calibration” ?
Auto calibration is a function designed to enable long-term accurate measurements for the RTR-576 by gradually adjusting the lowest measured CO2 concentration over a 180 hour period, to the global average concentration (atmospheric CO2 level of 390 ppm).

Turning ON and OFF Auto Calibration
Turn off auto calibration1 when continuously measuring in an environment where the lowest CO2 concentration differs greatly from the global average concentration of 390 ppm. In this case, to ensure accurate measurement results, periodically place the RTR-576 in fresh air outside and check if the measured CO2 concentration values are close to 390 ppm or not. If not, we recommend that you carry out manual calibration2.

  1. Auto-calibration ON/OFF can be changed from the Windows software for your Base Unit – Settings Utility – [Remote Unit Settings].
  2. The measurement of the CO2 sensor may have a slow drift. It is recommended to perform manual calibration about once a month. For details of the manual calibration procedure, please see the below on this page.

Cautions about using the Temperature-Humidity Sensors

  • If extremely severe temperature changes occur, the humidity measurements may appear abnormal. Once the sensor’s temperature becomes stable, the measurements will return to normal.
  • Do not connect the sensor to any data logger other than those specified by T&D Corporation.
  • Do not expose the sensor to a strong impact. This may adversely affect measurement accuracy and cause damage or malfunction.
  • When the sensor is not to be used for a long period of time, please store it at normal temperature and humidity.
  • Do not use the sensor on the human body.
  • Do not expose to condensation, dampness, corrosive gases, or organic solvents.
  • Continued use may cause a decrease in the sensor’s accuracy and sensitivity even under normal operational conditions.
  • This sensor is not water resistant. Do not allow the sensor to become wet. If the sensor gets wet, immediately remove the sensor from the unit and wipe it with a clean cloth as soon as possible. Then allow the sensor to dry in normal room temperature before using it again.
  • When using the THA-3001/3151 sensor in an environment where the humidity is less than 30%RH, the measurements may sometimes fluctuate. This is not abnormal.

CAUTION Notes and Precautions for Installing Wireless Communication Devices
When installing wireless communication devices take special care in selecting locations so as to ensure proper communication. Note that even after a successful installation, due to changes in environmental conditions, communication errors may occur when restarting the system.

  • As far as possible, try to keep wireless communication devices away from metals and set them up in high unobstructed positions.
  • Please take note that in many instances, walls, floors, stairs, fences and desks will contain metals. In order to carry out communication between indoor and outdoor units, please locate indoor units near a window so that radio waves can be easily transmitted.
  • Please install the Unit more than 30 cm away from walls or boards containing metal.
  • If the Unit is placed in a metal container such as a freezer or refrigerator, the possible wireless communication range will be shortened. In most cases radio waves are transmitted via doors and door openings so place the Unit as near to doors as possible.
  • As far as possible, keep the Unit away from noise-emitting sources.
  • Equipment such as some industrial instruments, electronic devices or fluorescent lamps generate noise. Please place the Unit more than 1 meter away from such devices.
  • Please place the Unit more than 1 meter away from computers and other devices which emit noise.
  • Keep all wires as far away from wireless communication devices as possible. Please be careful about placing near any wiring or cables such as power supply cables, telephone wires or LAN cables.
  • Objects which contain lots of water, such as plants or soil, absorb radio waves. We highly recommend that such materials should not be placed between or near wireless communication units.
  • When measuring temperature in a greenhouse it has been reported that as plants grew, communication errors also increased.
  • Do not place the Unit directly on the ground.
  • Do not place Units which are using the same communication frequency channel in the same area. If the same channel is used for multiple units not only will more communication errors occur, but battery life will also be shortened.
  • If there is a possibility that Units with the same frequency channel will be in wireless communication at the same time, please make sure to make changes to the frequency channels so they are not the same.
