Sentek SOLO probes can be configured either through the Head Unit using a Solo Download Cable or through
the TTL port on the probe interface using a PConfig cable. Please refer to the PConfig User Guide or Help file for
the complete usage instructions on how to configure Sentek
probes.
Probe Configuration Utility (PConfig) Software
Open Probe Configuration Utility software and check that the probe interface has the latest firmware version. This
can be found in the bottom right hand section of Probe Configuration Utility. The latest version is available on
Sentek’s website.

Configuration tab
1. Press the
Auto-detect Sensors
button to force the probe interface to read what sensors are attached to the
probe
2. Within the Configuration tab, set the depth of each sensor by clicking inside each cell within the Depth column
and change the number by either clicking the up and down arrows or by typing the depth in. Sensors with
addresses from 65 – 80 (Salinity) will automatically update depths once all other configuration information has
been entered and written.
3. Normalise probe (air and water counts)
a) To obtain the High (Air) counts for each sensor; place the probe
inside its access tube
. Then ensure
that there are no obstacles (i.e. hands, cables, soil, tables etc.) within the sensor’s sphere of influence
(20cm) and click on the header row of the High/ Air column so that the interface takes a reading from
each sensor.
Note:
Alternatively, the Air counts can be taken one sensor at a time by clicking on the lightning
bolt next to each sensor
b) To obtain the Low (Water) counts, fill your Normalisation Container with water, slide the probe into the
access tube until the first sensor is in the middle of the container. In the Low/Water column click on the
lightning bolt in the corresponding row of the sensor being read. Repeat for each sensor, and
remember to take a water reading for both moisture and VIC when normalizing TriSCAN sensors.
