*1
: Compatible wire sizes are as follows. Single Wire : 0.32 to Ø 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
: If you wish to use the WPS feature, set the security type of the wireless LAN access point to "WPA2-PSK(AES)" or "None".
*5
: HTTP client. Proxy supported.
*6
: When using external power, the internal temperature of the logger rises.
*7
: Battery life is highly dependant on the Auto-upload interval; at 1 min will give 10 days of usage, and at 12 hours or more will yield the maximum lifetime. Other influential factors include 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
: Shows the estimated battery life with Bluetooth ON. It will be 1.2 times longer with Bluetooth OFF.
*9
: Shows the estimated battery life with Auto-Upload ON.
*10
: -10 to 45°C when using external power (TR-7nw only).
*11
: For installation, it is necessary to have Administrator (Computer Administrator) rights.
