    • *1 ： For TR-71wf : When wireless LAN communication is used frequently, the measurement of the internal sensor may rise by around 0.3°C.
      For TR-71nw : When using PoE or USB as the power supply, the data logger itself generates heat and internal sensor will report a temperature approximately 15°C higher than ambient.
    • *2 : The WPS feature is not available when WEP(64bit/128bit) or WPA-PSK(TKIP) is selected in Access Point Settings. If you wish to use the WPS feature, please select WPA2-PSK(AES) or disable wireless security.
    • *3 : HTTP client. Proxy supported (for firmware version 1.05 or above for TR-7wf ).
    • *4 : Battery life varies depending upon multiple factors including 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.
    • *5 : Approx. 10 days when Auto-upload Interval is 1 min, 1 yr when 1 hr, 1.5 yrs when 12 hrs or more.
