*1) When used in environments where temperature and humidity are over the values of 50°C 75%, 60°C 50%, 70°C 35%, and 80°C 25%, sensor hysteresis may fluctuate by values greater than ±1.5%RH. Under certain circumstances, it may take some time to return to normal measurement capability. *2) Compared to the value measured by the T&D standard sensor for calibration under our calibration light source. *3) Only "Endless" is available when using RTR-500W for Windows. *4) If necessary, serial communication can be established by using our communication protocol (contact your local distributor) to write a software program. In such a case, an optional serial communication cable (TR-07C) is needed. *5) Battery life varies depending upon the ambient temperature in which it is used, the recording interval, the frequency of communication, and the battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life. When infrared communication function is enabled, battery life may be shortened if the unit is used under the inverter type fluorescent lighting.
