c. Finally, insert the shovel again into the soil a few inches away

from the probe, and gently force soil toward the probe to

provide good contact between the probe and the soil.

2. For deeper installations:

a. Excavate down to the level you wish to measure.

b. In the exposed wall, cut a pilot hole as described above.

c. Saturate the pilot hole with water.

d. Insert the senor(s).

e. With a shovel or blade a few inches away from the probe,

squeeze the soil onto the probe. This will improve the soil-to-

probe contact.

f. Fill the hole with the digged soil preserving the original soil

profile and compaction.

3. Pull the sensor cable(s) close to the logger enclosure.

4. Connect the signal cable to the applicable connector of the logger.

If you have purchased a sensor without factory made connectors,

see Wiring Instructions in the Technical Data chapter.

When removing the probe from the soil, do not pull it out of the soil by

the cable. Doing so may break internal connections and make the probe

unusable.

Submersible Water Level Sensor

Water level sensor has a ready-made cable and a connector. The length

of the cable defines the maximum distance from the logger. You have

to install the sensor on a solid fixture in water.

1. Choose a desired location for the sensor. Assure that the sensor is

located within cable length of the logger enclosure.

2. Make a solid base for the sensor to the desired installation depth in

water.

3. Position the sensor firmly to the base.

4. Connect the cable to the logger enclosure.
