1 INTRODUCTION
RST’s Digital MEMS 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 the Digital Inclinometer app that functions
as a readout, analysis, and data storage device.
The digital inclinometer probe incorporates cutting edge micro electro-
mechanical systems (MEMS) 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 or baseline reading, represent changes occurring in the subsurface. The
Digital MEMS Inclinometer System can accurately measure the rate, depth, and
magnitude of these deviations.
The Digital MEMS Inclinometer System measures lateral movement of
earthworks or structures, landslides, and embankment fills. It can be used to
monitor stability adjacent to excavations or underground workings and deflection
of piles, piers, abutments or retaining walls.

3 PROBE TYPES
The new digital probe resembles that of the traditional analog probes sold by
RST. The 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 metric probe can negotiate a radius of 1.88m (74”) in 70mm (2.75”) OD
inclinometer casing. The digital inclinometer will continue to provide readings
past the limit for other probes on the market.
Figure 2: RST Digital MEMS Inclinometer digital probe sizing vs. competitor inclinometer
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.
CAUTION: The digital probe also uses shear pins on the wheel assemblies. If the
probe gets stuck in the inclinometer casing, apply a force of approximately 300 lbs
to shear pin to prevent damage to the probe or cable. Contact RST Instruments Ltd.
for instructions on retrieving a probe that is stuck in a hole and replacing the probe
shear pins.

3.1 VERTICAL PROBE
Vertical probes collect data in the A and B axes and are the most used probes.
Readings taken from an inclinometer probe are deviations from the vertical over
the distance between the upper and lower wheels. When the probe is passed
through the inclinometer casing, a reading is taken every 0.5m (or 2 feet). When
the probe is at rest, the MEMS accelerometers sense the inclination of the
access tube in two planes. This inclination in terms of angular deviation
(recorded at that depth) appears on the handheld device’s screen.
3.2 SPIRAL PROBE
The RST Digital Spiral Probe is designed to complement the Digital MEMS
Inclinometer System. In situations where excessive spiral is present in the
inclinometer casing, it becomes important to correct for the spiral to have the
correct magnitude of displacement in the A and B axes. A spiral sensor is used
to determine the true azimuth of inclinometer casing after installation.
The spiral sensor is connected to the digital inclinometer reel just like a standard
RST digital inclinometer probe. The Digital Inclinometer app automatically
senses the digital spiral probe. The probe is then lowered to the base of the
borehole and the survey is performed in 0.5 metre (or 2 feet) intervals
depending on whether a metric or imperial system is being used. Readings are
displayed on the handheld device in degrees. Device recommendations are
discussed in section 6.2.
After data is collected, it can be imported into the RST InclinalysisTM Software. A
spiral correction can then be applied to the digital inclinometer data and plots of
the corrected borehole data can be created.
NOTE: For information on the InclinalysisTM Software, contact RST Instruments
Ltd. or visit our website at http://www.rstinstruments.com.
3.3 DUMMY PROBE
Dummy inclinometer probes for use in testing in boreholes are available for
purchase from RST. RST encourages customers to try the new digital dummy
probe in existing holes where the competitor’s probes do not work. If the dummy
probe passes through all areas of the casing, the RST Digital MEMS
Inclinometer System will work. 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. Contact RST Instruments Ltd. to
purchase a dummy probe.

4 VERTICAL DIGITAL PROBE
4.1 SIGN CONVENTION AND MEASURED DEVIATION
The vertical digital 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 (referred to as the
“baseline reading”), 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
should be taken by placing the upper wheels of the probe in the casing groove
closest aligned to the downslope direction. Figure 3 illustrates an inclinometer
casing installed with a groove orientation in the general downslope direction.
Figure 3: Probe orientation
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. RST recommends
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 are 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, which is the lateral displacement in the direction of the axis of
measurement
L = inclinometer probe length, typically 0.5 m for a metric probe or 2 feet for an
imperial probe
α= inclination angle of probe from vertical axis

Page 11
The Digital MEMS 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 as shown in Figure 4.

5 INCLINOMETER CABLE AND REEL
The RST Digital MEMS 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 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 5 mm (0.25”) of one another between subsequent surveys.
For accurate repeatability, two aluminum cable grips are provided with the
system, for 70 mm (2.75”) and 85 mm (3.34”) OD casing respectively. The cable

Digital MEMS Inclinometer System with Android App
Instruction Manual
ICM0099C
07-Mar-2023
RST Instruments Ltd.
Page 12
grips provide a solid reference for the cable crimps to sit in. This results in
reduced operator error, with checksums 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.
NOTE: Avoid running the cable over sharp edges and to periodically clean it with
a soft 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.
5.1 INCLINOMETER REEL 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. A full charge will last around 30 hours. Monitor the battery status. Do
not let the battery completely discharge.
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, and the
battery is not removable. Do not try to remove the battery. See Section 15.1
for battery status and Section 15 for battery charging instructions.
If the serial number is 2499 or lower, the battery can be removed and
recharged. Refer to Section 15 for instructions on removing and recharging the
battery.

5.2 CHARGE THE BATTERY –REEL WITH SERIAL NUMBER 2500
OR ABOVE
NOTE: Do not follow these instructions if the reel serial number is 2499 or lower.
Refer to Section 15.
To charge the battery on a reel with a serial number 2500 or higher, locate the
battery port on the side of reel. Turn the cap counterclockwise to unscrew. Plug
the charger into the battery port and begin charging. After charging is complete,
place the cap back and tighten.
Figure 7: Reel battery port
Figure 8: Plugging charger into battery port
5.3 TURN ON WIRELESS COMMUNICATION
Press the power button to the left of the battery port. A solid green light appears
to indicate power is on. The reel automatically broadcasts its device name and
continues to broadcast for up to five minutes. During this five-minute window,
the Digital Inclinometer app must establish Bluetooth connection with the reel. If
the app unable to connect to the reel, the reel powers down to reduce battery
consumption.
The reset (power) button has a green light that indicates the reel’s status. No
light indicates reel power is off. Solid light indicates power is on, but the reel is
not connected to the Digital Inclinometer app. Blinking green at one second
intervals mean the reel is connected to the Digital Inclinometer app.
5.4 CHECK REEL AND PROBE STATUS

•Voice call or text messaging –the Android device has capability to call a
contact person. If this feature is required, an activated voice SIM card
must be inserted and configured.
•Gmail account to allow the app to send collected data by email.
•Font size and screen zoom settings to allow the app to properly display
and avoid truncated words and excessive word wrap. RST recommends
initially setting the device with the smallest font size and zoom setting
and increasing incrementally to the desired appearance.
•Screen timeout set to a large timeout value, such as 30 minutes. This
setting specifies the time before the device enters sleep mode.
•Correct date and time setting as the app embeds this information in the
data.
6.4 DIGITAL INCLINOMETER APP WORKFLOW
6.4.1 Screen Sections
The Digital Inclinometer app is designed to simplify workflow and allow the user
to access functions with a minimal number of taps. The screen has three
sections and layout is always in a portrait mode to display scrollable lists and
graphical plots.
1. Title bar on the top, shows context-sensitive
content. Additional controls, if applicable, are
located at the left or right corner
2. Middle screen shows the context-specific
content
3. Status bar on the bottom, shows connection
status of the reel and probe, and other non-
context specific content
