a. When the probe is partially installed, remove 5 cm (2 inch) of soil from the top of the
hole. This will prevent the connector from digging into the soil as the probe is
installed, and provide room for connecting the cable.
b. To ensure good contact, carefully replace the soil while adding water and packing
well. When the top of the probe is flush with the soil surface, the top sensor is at
5 cm (2 inch) depth.
5. Connect the cable to the SoilVUE 10, and hand tighten the cable connector nut to ensure a
water-tight seal. Do not over tighten. The cable nut should turn easily. If it does not, check
to make sure it is correctly aligned. Also, try gently pushing in on the cable.
WARNING:
Do not over tighten. Never use a wrench or spanner on the cable connector nut
because it will damage the connector.
6. Route the cable to the data logger.

U and C terminals are automatically configured by the measurement instruction.
For the CR6 and CR1000X data loggers, triggering conflicts may occur when a companion
terminal is used for a triggering instruction such as
TimerInput()
,
PulseCount()
, or
WaitDigTrig()
. For example, if the SoilVUE 10 is connected to C3 on a CR1000X, C4 cannot
be used in the
TimerInput()
,
PulseCount()
, or
WaitDigTrig()
instructions.
7.4 SDI-12 programming
This instruction sends a request to the sensor to make a measurement and then retrieves the
measurement from the sensor. See
(p. 12) for more information.
