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:

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).

TAKING READINGS
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 X2.2X).
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.

6. Once the probe is at the desired depth, place the cable grip on the top of the casing
and hang the cable by the aluminum crimps. The objective is placement
repeatability within 5mm (0.25 inch). This is extremely important to ensure accurate
and repeatable results.
7. The probe will begin profiling the borehole from the bottom of the borehole. After
each respective measurement has stabilized and a recording has been taken, pull
the probe upwards to the next desired measurement depth. If you accidentally pull
the probe too far, lower the probe back down to the previous measurement depth,
and then pull it back to the next intended measurement depth. This procedure
ensures that the readings will remain consistent. For maximum measurement
repeatability, keep the cable as clean as possible during this process. If possible, a
tarp or basket can be useful to avoid placing the cable directly on the ground.
8. Allow the readings to stabilize at each location. Reading stability can be gauged by
both the noise bar and the standard deviation, which are displayed on the Readings
List (Section 4.3.7).
9. Once the readings have stabilized, press the Accept button and move the probe to
the next interval as prompted by the software.
10. Repeat Steps 7-9 until the probe reaches the top of the borehole. The App will then
prompt you to turn the probe 180 degrees and repeat the survey, this time in the A-
direction (i.e. with the lower probe wheels in the A+ groove).
Warning
When the probe has reached the top of the casing, avoid allowing the wheel
assemblies to snap out of the casing. As the wheels reach the top, grasp them
with your hand and release the wheel assembly slowly until it reaches the stops.
Failure to do so will damage the shear pin and subject the MEMS
accelerometers to sudden shock, which can damage them and affect the
calibration of the probe.
Warning
Do not drop the cable aluminum crimps onto the cable grip. The cable has very
little stretch, especially near the top of hole, and the impact on the cable crimps
may “hammer” them out of position or break the cable. This effect has been
demonstrated for drops as little at 70 mm.
Warning
Never tightly coil or sharply bend the cable during this process, as this can cause
permanent coiling or twisting of the cable which can impact the spacing of the
aluminum crimps and measurement repeatability. It is recommended to lay the
cable in a “figure-8” or “spaghetti bowl” pattern as follows:
a. “Figure-8” Cable Management: As the probe is brought up-hole, lay the
excess cable on a clean surface in alternating loops to form a figure-8 pattern.
The loops of the figure-8 should be approximately the size of the cable reel
diameter. Once the survey is complete, flip over the bundled figure-8 of cable
for easy spooling back onto the reel.
b. “Spaghetti Bowl”Cable Management: As the probe is brought up-hole, allow
the cable to freely coil as it is laid on a clean surface. Do not attempt to twist
or coil the cable, as this can deform the cable with repeated use.

11. Prior to lowering the probe for the second pass, remove the cable grip to avoid
accidentally catching the aluminum crimps on the cable grip (this will impact load the
crimps, cable, and probe). Once the probe is at the bottom of the borehole, replace
the cable grip and position the probe for the deepest reading.
12. Repeat Steps 7-9 to take a second pass of readings in the A- direction. During this
second pass, checksum data will be displayed underneath each reading. Ensure
that these remain small and consistent; however, checksums can vary due to
different site conditions. Large checksums can indicate errors in probe positioning or
fouling of the probe. Expect checksums to be slightly larger when the probe
encounters an expansion coupling in the casing (if applicable). Refer to Section 6
for further detail on checksums.
13. The RST MEMS Digital Inclinometer has the ability to perform data reduction in the
field, please refer to Section X4.2.8Xfor information on viewing and validating the data.
14. Upon completion of the survey, close the inclinometer app, turn off the power to the
reel, and disconnect the probe. Wipe off the probe and cable. If possible, rinse the
probe and cable with fresh water. Replace end caps on the cable and probe.
Replace the protective cap on the casing.
15. Upon returning to the office, clean the instrument and reel once more to remove any
moisture from the instruments and the case. Recharge the batteries for the Reel
and the Android data collection device. Please refer to Section 8 for proper care
and maintenance of the system.
16. If required, transfer the collected data files via email or file transfer.
3 INCLINOMETER CABLE AND REEL
The RST MEMS Digital Inclinometer System comes with a durable lightweight reel that is
easy to handle. Since only a pair of conductors is needed in the cable, the weight and
dimensions of the cable are drastically reduced as compared to a traditional analog cable.
The reel is battery powered and houses the electronics used for wireless communication.
An important part to any inclinometer casing survey is the repeatability of the depth
measurements. It is extremely important that measurements be consistently within 5mm
(0.25”) of one another between subsequent surveys. To facilitate accurate repeatability, two
aluminum cable grips are provided with the system, for 70mm (2.75”) and 85mm (3.34”) OD
casing respectively. The cable grips provide a solid reference for the cable crimps to sit in.
The result is that operator error is reduced, checksums will be smaller and surveys more
accurate.
The thin, strong cable contains a Kevlar® strength member, allowing a long length of cable
to fit on a small reel with no stretch. The aluminum sleeved measure marks are precision
swaged to the cable and are not subject to tearing when handling. The measure marks are
spaced at 0.5 metre or 2 feet intervals. The cable is marked with a red measure mark and a
label every 5 metres or 10 feet, depending on whether the metric or imperial system is being
used. The urethane jacket is highly abrasion resistant and maintains flexibility at low
temperatures. It is good practice to avoid running the cable over sharp edges and to
periodically clean it with a soft clean cloth. Be sure to keep the protective cap on the
connector whenever the probe is not in use and avoid dropping or banging the cable end.
Always keep the connectors and threads clean by rinsing them with water and be sure to
lubricate frequently. Exercise care when connecting and removing the cable from the probe;
make sure to only turn the connector ring, not the entire cable.

INCLINOMETER REEL BATTERY
If the serial number of the reel is 2500 or above, the battery is contained inside the
inclinometer reel. The inside of the reel is not accessible to the user and the battery is not
removable. Do not attempt to remove the battery.
The inclinometer reel has a green LED light that will flash to indicate battery status (Table 1).
The LED light on the reel will flash when the power button is pressed.
Monitor the battery status. Do not let the battery completely discharge. A full charge will
last around 30 hours.
Note
For reels with serial numbers under 2500, refer to Appendix A for instructions on how to
remove and recharge the battery. Only batteries on reels with serial numbers under 2500
may be removed from the reel. Do not attempt to remove the battery from the reel if the
serial number on the reel is 2500 or higher.
For reels with serial numbers of 2500 or higher, refer to Section 3.1 for battery status and
Section 3.2 for instructions on how to recharge the battery. Only reels with a serial number of
2500 or higher may be recharged. Do not attempt to remove the battery from the reel if the
serial number of the reel is 2500 or higher.

Refer to Appendix A if the reel serial number is under 2500. Do not proceed with the
following instructions if the reel serial number is under 2500.
The following instructions are for reels with serial numbers of 2500 or higher.
The battery will need to be recharged using the provided charger. The battery port may be
accessed by unscrewing the cap on the outside of the reel. Refer to Figure 7 for the location
of the battery cap.
Figure 7 –Unscrewing the Battery Cap
Unscrew the battery cap by turning it counter clockwise. The charger will plug into the port
and begin charging the battery. Replace and tighten the cap when the charger is not in use
to ensure debris does not enter the battery port.
WIRELESS COMMUNICATION
Turn on the power to the reel by pressing the button located to the left of the battery housing
on the Reel Hub (Figure 7). A solid green light indicates the reel has been powered on.
After turning on the power to the reel, it automatically broadcasts its device name and will
continue to broadcast for up to 5 minutes. During this 5-minute window, the Digital
Inclinometer app must establish a Bluetooth connection with the reel. If the Reel Hub is
unable to connect to the Digital Inclinometer app, the Reel Hub powers down to reduce
battery consumption.

The Reel Hub reset button is equipped with a green light status indicator, The status light
indicates that the Reel is in one of the following three states:
•Off –the Reel Hub is powered off.
•On –the Reel Hub is powered up, but not connected to the Digital Inclinometer app.
•Blinking at 1-second intervals –the Reel Hub is connected to the Digital
Inclinometer app.
4 ANDROID DIGITAL INCLINOMETER APP
The RST MEMS Digital Inclinometer System app runs on most Android devices running
Android 5.1 and higher. The Android device functions as a readout and data storage device.
Data reduction can be performed on site as soon as the survey is complete. The app is
equipped with data visualization features to qualify data accuracy.
REQUIREMENTS
The Digital Inclinometer app can run on Android device with Android 5.1 and higher. The
device should be Google Mobile Services certified and be pre-installed with apps such as
Google Play and Google Gmail.
The Android device must be equipped with a Bluetooth classic capability to support wireless
connectivity with the legacy and latest generation inclinometer systems.
Other wireless networking capabilities such as Wi-Fi and Cellular are recommended for
remotely updating data collection files over email services.
DEVICE RECOMMENDATIONS
The process of collecting data at the borehole is a demanding task. The device is often
subjected to harsh environmental and field conditions. Due to these considerations, RST
recommends only rugged Android devices that can withstand the daily rigours encountered
in the harshest environment, such as the Samsung Galaxy Active 2, the Juniper Mesa3, and
Juniper CP3 smartphone/tablets.
