Notes about Operation Setting up the RTR 576 This product has been designed for use in normal living conditions and is not suited for controlled environments such as a CO2 incubator When measuring outdoors avoid exposure to sunlight dust rain or wind Also make sure to use in the operating environment indicated in the specifications Wireless CO2 Recorder A N Do not connect an RTR 576 to your computer before first installing the supplied software that comes with the Base Unit you are using This product cannot measure CO or O2 Do not use it for purposes such as avoiding Connect the Sensor Turn on the POWER gt switch O2 deficiency CO intoxication or any other health related purpose After setting up the power supply turn on the POWER switch ON position e See for notes about turning off the POWER gt switch RTR 576 User s Manual Thank you for purchasing our product To ensure safe and proper operation please read this manual thoroughly before use For one to two weeks after installation of the unit CO2 concentration measurements may fluctuate suddenly This is due to the normal operation of Auto Calibration and is not a malfunction of the RTR 576 RTR 576 Package Contents RTR 576 H Package Contents Do not use or store the unit in areas exposed to direct sunlight and abrupt changes in temperature Warm up Time for CO2 Sensor After swit
4. Auto Calibration Auto calibration is a function designed to enable long term accurate measurements for the RTR 576 by gradually adjusting the lowest measured weekly CO2 concentration to the global average concentration atmospheric CO2 level of 400 ppm e The factory default setting for auto calibration is ON Turning ON and OFF Auto Calibration Turn off auto calibration 1 when continuously measuring in an environment where the lowest weekly CO2 concentration differs greatly from the global average concentration of 400 ppm In this case to ensure accurate measurement results periodically place the RTR 5 76 in fresh air outside and check if the measured CO2 concentration values are close to 400 ppm or not If not we recommend that you carry out manual calibration 2 1 To change the settings it is necessary to download Adjustment Tools application free from our website at http www tandd com support download software 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 refer to the Adjustment Tools Help which you can access from the Help button in the application window Cautions about using the Temperature Humidity Sensors e f extremely severe temperature changes occur the humidity measurements may appear abnormal Once the sensor s temperature becomes stable the measurements wil
