*1: Compatible wire sizes are as follows.
Single Wire : 0.32 to 0.65 (AWG 28 - 22), Twisted Wire : 0.08 to 0.32 ( AWG 28 - 22 ), 0.12 or more in diameter, Stripping Length : 9 to 10
*2: When Auto Upload is used frequently, the measurement of the internal sensor may rise by around 0.3°C. When using external power, the data logger itself generates heat and the
internal sensor will report a temperature much higher than ambient; we recommend using an external temperature sensor in this case.
*3: When continually used in environments with temperatures above 60 °C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20 °C.
*4: 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.
*5: HTTP client. Proxy supported. ( for frmware version 1.05 or above for TR-71wf/72wf ).
*6: When using external power, the internal temperature of the logger rises.
*7: 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.
*8: For installation, it is necessary to have Administrator ( Computer Administrator ) rights.
*9: We recommend using an operating system in the same language as the display language. Operation in different languages is not guaranteed.
