EADINGS
1. Upon arrival at the site, remove the protective caps from the casing, the probe, and
the control cable. If possible, flush the borehole with clean water prior to taking
measurements.
Groundwater with high salinity or suspended particulate
content can damage the bearings in the probe wheels with repeated use.
2. Attach the probe to the reel by aligning the keyways and threading the connector
onto the probe.
Ensure the connector is lubricated, clean, and free of debris
prior to making the connection.
Take care to turn only the threaded ring, not the
cable itself. Do not over tighten the connector; a hand tight connection is sufficient.
3. Once connected, turn on the power to the reel. This energizes the MEMS
accelerometers and makes them less susceptible to shock.
4. Insert the probe into the borehole, aligning the upper wheel in the direction of the A+
axis (see Section
5. Lower the probe to the desired depth
slowly
and as
smoothly
as possible.
Be
extremely careful not to bounce the probe off the bottom of the hole. Any
shock to the probe may damage the probe electronics and affect its
calibration.
Warning
Handle the inclinometer probe very carefully as the accelerometers are very
susceptible to shock.
