The View Readings List is displayed when the user selects a particular borehole from the
View Borehole List screen. The View Reading List displays a listing of readings taken from
the borehole sorted based on the borehole reading timestamp.
Each reading shows the reading completion date and time. If the reading were incomplete,
the reading status displays “Incomplete”. The user may resume taking readings from an
incomplete reading.
The user may also tap the edit icon to edit the borehole information.
The user may tap the Graphs tab to view the combined graphs of readings from the
borehole. A description of the combined graphing capability is detailed in Section 4.3.8.
The user may tap on a desired reading to view borehole readings taken on a specific date or
resume taking readings from a previously incomplete session.
The user may also tap the + ADD READINGS button to add a new reading. A description of
the Add Readings feature is detailed in Section 4.3.9.
A sample reading list is shown in Figure 16.

The Digital Inclinometer system has been developed to accurately measure the lateral
movement of earthworks and structures. The probe is passed through the inclinometer
casing and a reading is taken every 0.5m or 2ft. When the probe is at rest,
servo-accelerometers sense the inclination of the access tube in two planes. This inclination
is displayed in terms of angular DEVIATION, which is recorded at that particular depth.

The View Readings Comparison Graph feature combines the multiple readings from one
borehole and compares the result against a specific base reading. Typically, a base file is
chosen (typically in the form of an initial reading) and kept the same throughout the life of the
inclinometer hole in order to quantify any lateral displacement that occurred. The comparison
