Storage

All equipment should be stored in an environment that is protected from direct
sunlight. It is recommended that equipment be stored in a dry environment with
caps in place.
Batteries should be charged regularly, even when the equipment is not in use, to
maintain their capacity and life expectancy. If the probe is to be stored for long
periods, a light coat of light lubricant on the moving parts is advisable.
Whilst in storage, it is vital that storage areas should be free from rodents as they
have been known to damage cables and cases.
No other special requirements are needed for medium or long-term storage although
temperature limits should be considered when storing any such instruments and
readout equipment.

6. INCLINOMTER CASING INSTALLATION THEORY

6.1.

Baseline

Prior to any survey taking place, the appropriate Geosense® Inclinometer Casing
will need to have been installed on site. The Geosense® Horizontal Inclinometer
system can be used to measure the profile of the casing in relation to a presumed
fixed point.
If the system is being used to measure construction related movements in the heave
or settlement process, it is good practice to set a baseline period before any
monitoring for subsequent changes is undertaken. The baseline period may consist
of different time periods based on site conditions.
Geosense® recommends that any site works have a suitable baseline period active
before monitoring of settlement/heave using a horizontal system is used. This allows
for seasonal and diurnal changes not related to the ongoing construction works to be
understood and these can then be isolated from other movements in future review of
the data.
A baseline period may not be relevant if the movement to be monitored is ongoing
and not related to a specific activity on site that can be modally influenced.

Depending on the type and cause/source of any expected movement, it may be
necessary to tailor installations to individual project needs. The below scenarios
represent two such types of installation that may be used. Variations of these
installations may also be used dependent on unique site situations.
