Operation
Connecting External Power
The T1R comes with two AA internal batteries. This provides enough power for at least
one year of operation at the rate of four measurements per hour.
If auxiliary power is desired, you can use a 6 - 13 VDC supply that can provide 15
mA. Connect to Vaux++ (pin 1 - white) and Ground (pin 5 - blue) or contact INW for
auxiliary power supplies.

instructions come with the adapter. (For alternate connection options, see Alternate
Connection Options Section.)
