The T8 is fitted with an 8-pin plug. The plug can be connected to an
INFIELD7 handheld measuring device. The INFIELD7 displays and
stores the soil water tension, the soil temperature and the filling

For connecting T8 to a data logger or any other data acquisition
devices connecting and extension cables are required. Find T8

If the Tensiometer is not permanently powered the warm-up
before a measurement should be at least 10 seconds.
The Tensiometer plug should be covered with the supplied
protective cap anytime the T8 is not connected to an extension
cable.
Never connect the signal outputs of the T8 to a supply voltage
source!
The supply voltage must not exceed 18 VDC.
