Digitilt Probe Manual, 2006/8/09 3
Handling
the Probe
The inclinometer probe is a sensitive measuring instrument. Handle it with care.
•Transport the probe in its carrying case. If you drive to the site, carry the casing
in the passenger compartment, preferrably on a passenger seat.
•When you connect control cable to the probe, avoid overtightening the nut, since
this will flatten the O-ring and reduce its effectiveness.
•Before you lower the probe into the casing, turn the power on.
•When you insert the probe into the casing, cup the wheels with your hands to
compress the springs and allow smooth insertion.
•When you lower the probe into the borehole, do not allow it to strike the bottom.
•When you withdraw the probe from the casing, again cup the wheels with your
hands to prevent them from snapping out.
•When you rotate the probe, keep it upright and perform the rotation smoothly.
•The probe is rated for temperatures from -20 to 50 °C (-4 to 122 °F). Avoid using
the probe in temperatures outside this range.
Caring for the
Probe
This is an overview. See the last chapter, Inspection and Maintenance, for addi-
tional information.
Cleaning the Probe: When you finish a survey, wipe moisture off the probe and
replace the protective cap. If necessary, rinse the probe in clean water or wash it
with a laboratory grade detergent when you return to the office.
Cleaning the Connectors: Do not clean connectors with spray lubricants or electri-
cal contact cleaners. Solvents in these products will attack the neoprene inside the
connector. When it is necessary to clean the connectors, use a cotton swab slightly
moistened with alcohol. Be careful to use only a small amount of alcohol.
Drying the Probe: When you return to the office, remove protective caps from the
control cable, probe, and readout unit. Allow connectors to air-dry thoroughly for a
number of hours. Afterwards, replace the caps.
Storing the Probe: The probe, control cable, and readout unit should be stored in a
dry place. For extended storage, keep the probe in a vertical position.
Lubricating the Wheels: Lubricate the wheels regularly. Spray a small amount of
lubricant or place a drop of oil on both sides of the wheel bearings. Check that the
wheels turn smoothly.
O-Ring Care: Periodically clean and lubricate the O-ring on the connector end of
the inclinometer probe. Use O-ring lubricant.
