*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: Battery life varies depending upon the frequency of communication, LAN environment, ambient temperature, recording interval, and 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.
*3: For installation, it is necessary to have Administrator ( Computer Administrator ) rights.
*4: If you are using Windows 8, please note that our software is designed to be used in "Desktop" mode only.
*5: We recommend using an operating system in the same language as the display language. Operation in different languages is not guaranteed.
