Technical Terms of Reference / Transport
To avoid damage to the unit and prevent accidents during transport the Light
Weight Deflectometer is provided with a transportation lock which is fixed to
the guide tube during transport.
The LWD is equipped with a transportation lock designed to avoid
damage to the instrument and make sure that it can be safely
transported and handled. This lock must be used to secure the drop-
weight on the guide tube whilst the equipment is moved from job to
job.
The drop height determined for the drop-weight by calibration ( calibration
record) has been preset. The drop height is secured against changes and
must not be altered by the user.
Engage the drop-weight in the release mechanism prior to any test. To release
the drop-weight, just actuate the release mechanism.
Prior to any measurement, test the release mechanism to be sure it
functions as necessary.
Support the drop-weight by hand after every impact to avoid faulty
measurements.
