1 INTRODUCTION
The RST MEMS Digital Inclinometer System represents a breakthrough in inclinometer
system technology, providing unprecedented accuracy, efficiency and ease of use. The
system is comprised of a Digital Inclinometer Probe, cable system, reel with battery power,
and an Ultra-Rugged Field PC running Mobile Microsoft Windows™that functions as a
readout, analysis, and data storage device.
Wireless communication between the inclinometer control reel and the Ultra-Rugged Field
PC ensures ease of use and reliability, by removing two weaknesses inherent in
conventional analog inclinometer systems. By removing the physical connection between
the inclinometer control cable and the readout instrument there is no concern with fragile
connectors, cable related failure and related reliability problems. The Achilles heel of any
inclinometer control cable reel is the slip ring required to maintain electrical contact as the
reel revolves. As the RST system is wireless from the control cable to the readout, a slip
ring is not required, and there are no associated electrical continuity problems.
The RST digital inclinometer probe incorporates cutting edge MEMS (Micro Electro-
Mechanical Systems) technology providing high precision and durability. A highly accurate
survey of the inclinometer casing is used to establish the initial position of the casing. Any
subsequent deviations in the casing from this initial value (i.e. baseline reading) represent
changes occurring in the subsurface. The RST MEMS Digital Inclinometer System can
accurately measure the rate, depth, and magnitude of these deviations.
The information included in this manual outlines the use and care of the RST MEMS Digital
Inclinometer System. It provides examples of how to take readings and interpret the data.
For more information on the installation of inclinometer casing, and other related issues,
please contact RST Instruments Ltd.
Note
Proper care and maintenance of the MEMS Digital Inclinometer System will greatly
extend the life of the instrument and accuracy of the readings. Please take the time to
read this manual thoroughly. If any questions arise, do not hesitate to contact RST
Instruments Ltd. Proper maintenance of the probe after each use is outlined in Section
X12X.
Functions:
•Measure lateral movement of:
oEarthworks or structures
oLandslides
oEmbankment fills
•Stability adjacent to excavations or underground workings
•Deflection of piles, piers, abutments or retaining walls

2 DIGITAL PROBE
In general terms, the new Digital Probe resembles that of the traditional analog probes sold
by RST. The RST Digital Inclinometer has the smallest package available for a given wheel
spacing, with the best ability to track deformed casings. This means that the Digital Probe
can handle greater bends in the casing without becoming stuck. The RST metric probe can
negotiate a radius of 1.88m (74”) in 70mm (2.75”) OD inclinometer casing. The RST Digital
Inclinometer will thus continue to provide readings past the limit for other probes on the
market (see XFigure 2X).
Figure 2 –Digital Probe Sizing
The connectors, wheels, and wheel carriages are the most precise and durable in the
industry. The probe wheels are made of high grade hardened and heat-treated stainless
steel. These are extremely durable and the most robust on the market.
The digital probe also incorporates shear pins on the wheel assemblies. In the event that
the probe gets stuck in the inclinometer casing, a force of approximately 300 lbs is required
to shear the shear pin. No damage to the probe or cable will result. Please contact RST
Instruments Ltd. for further instructions on retrieval of a probe that is stuck
downhole, and the replacement of the probe shear pins.

DUMMY PROBE
Dummy inclinometer probes are available for purchase from RST for testing purposes in a
borehole. RST encourages customers to try the new digital dummy probe in existing holes
where the competitor’s probes do not work. If it is found that the dummy probe passes
through all areas of the casing, the RST MEMS Digital Inclinometer System will function.
Therefore, the existing hole will still be viable, and a new hole will not need to be drilled.
The RST dummy probe has the exact same weight and dimensions as the standard probe.
A ring is provided in place of the connector which allows the dummy probe to be lowered by
a rope. For further information on purchasing a RST Dummy Probe, please contact RST
Instruments Ltd.
SIGN CONVENTION AND MEASURED DEVIATION
The Digital Inclinometer Probe houses two MEMS accelerometers, which measure tilt in two
axes. Proper installation of the inclinometer casing attempts to align one set of grooves in
line with the axis of expected movement. This is called the A axis. The perpendicular set of
grooves is the B axis.
When an inclinometer casing is surveyed for the first time (i.e. baseline readings), it is
necessary to select a fixed direction reference for the probe so that each time a survey is
repeated, the probe will always have the same orientation in the casing.
For example, in an area suspected of landslide activity, the first set of readings would be
taken by placing the upper wheels of the probe in the casing groove closest aligned to the
downslope direction. XFigure 3Xillustrates an inclinometer casing installed with a groove
orientation in the general downslope direction.
In practice, it is often difficult to achieve exact orientation of grooves relative to some
predetermined direction. The groove closest to the anticipated movement direction is usually
chosen as the main reference direction. It is recommended that this direction (A+) be
marked on the casing itself to ensure surveys are performed in the same manner each time.
The azimuth of this groove direction can be measured in a clockwise direction from the main
reference direction (A+). All subsequent measured inclinometer movements would be
referred to this direction.
Readings taken from the inclinometer probe (see Section 2.3) are actually deviations from
the vertical over the distance between the upper and lower wheels (see Figure 4), calculated
as: D = L × sine(α)
Where: D = Deviation, e.g. lateral displacement in the direction of the axis of
measurement
L = inclinometer probe length (typically 0.5 m for a metric probe or 2 ft for an
imperial probe, as defined in Section 10).
α= inclination angle of probe from vertical axis

Figure 3 –Probe Orientation
The RST Digital Inclinometer System uses the industry standard sign convention, where tilt
in the direction of the upper wheels results in a positive deviation and tilt in the direction of
the lower wheels results in a negative deviation (XFigure 4X).
