3 System description
For the purpose of calculating the size of demolition charges, it is important to know the
exact position, direction and deviation of the drilled holes.
The Robit M Sense system measures the deviation of the hole using a gyroscope and
accelerometer inside the measurement probe. The measurement is performed by
lowering the measurement probe into the drilled hole and the measurement data is
transmitted to a computer when the module is lifted.
The measurement results are available immediately after measuring. The system also
provides a wide range of tools for examining the holes and analysing the field.
Note:
Borehole measurement accuracy is affected in certain borehole angles.
System azimuth accuracy decreases in red zones. Inclination accuracy is not
affected by the borehole angle.
These limitations affect the Gyro only and Compass assisted gyro measuring
modes.
3.1 System components
The Robit M Sense measuring system consists of the following components:

1. Measurement module embedded in an aluminum probe and a measuring cable
2. Tablet PC with measurement software and accessories
3. Protective case for system components.
3.2 Operating principle
The Robit Sense measurement software is a versatile tool for measuring boreholes. The
measurement data can be saved in a database, where it can be viewed after drilling or at
a later time.
Holes can be measured in two ways: 1) select a site and field before measurement,
which allows you to define what hole to measure, or 2) measure a hole first and decide
afterwards whether or not you wish to save it in a site. All holes measured in a field can
be viewed simultaneously, which provides a good overall view of the holes throughout the
field. A measured hole does not need to be connected to a worksite. Instead, it can be
saved in the database separately.
Selecting a field before measuring a hole
The site can be selected before measuring a hole, in which case the measurement is
done as follows:
1. Select the site, level and field.
2. Select the hole to be measured.
3. Press the Start measurement button.
4. Enter the starting angle of the hole, if it is known.
5. Lower the measurement probe into the borehole.
6. Press the Begin lifting button and start lifting the measurement probe from the
borehole.
7. Maintain the rod stationary for the time shown on the screen.
8. Mark the measurement points at predefined intervals points using the touchscreen.
9. Once the probe has been lifted, the hole measurement data is transferred to the
computer.
10. The data for the measured hole is linked to the selected hole automatically.
Measuring a borehole without selecting a field
Measurement is done as follows:
1. Press the Start measurement button.

2. Enter the starting angle of the hole, if it is known.
3. Lower the measurement probe into the borehole.
4. Press the Begin lifting button and start lifting the measurement probe from the
borehole.
5. Maintain the rod stationary for the time shown on the screen.
6. Mark the measurement points at predefined intervals points using the touchscreen.
7. Once the probe has been lifted, the hole measurement data is transferred to the
computer.
The hole data is saved as follows:
1. Select the worksite, level and field where the data is to be saved. If you do not select
a site for the hole, it will be saved independently in the database.
2. Select the hole from the drilled field.
3. Link the transferred information to the drilled hole.
3.3 User interface
The user interface of the Robit Sense M system is designed to be used with a touch
screen or mouse. The Robit Sense measurement software can be used to design drilling
fields, measure drilled holes, and inspect and analyse measurements with a range of
powerful graphical view and tools.

3.3.1 Cloud synchronization
The cloud synchronization icon briefly appears in the user interface when
data has been successfully synchronized with the Sense Cloud Service.
If the synchronization fails for some reason, the synchronization error icon
is displayed. This icon disappears after successful data synchronization.

4 Operating instructions
Note:
Before first use, the measuring system needs to be calibrated according to the
calibration instructions.
4.1 Starting up the software
Procedure
1. Start up the Robit Sense software by tapping the software icon on the tablet
computer.
2. Once the software has been activated, enter the measuring cable marking interval in
metres or feet (imperial cable).
The marking interval defines the distance between individual measurement points
during borehole measurement.
Once the cable marking interval has been approved, the program moves to the home
screen where you can select the desired function.
4.2 Compass calibration
Compass calibration should be performed before beginning measuring in a new site. This
is especially important if previous calibration was done far enough so that the Earth's
magnetic field is different. While performing the calibration keep away from any potential
sources of magnetic interference such as buildings and vehicles.
Procedure
1. Hold the measurement module at about 15 cm (½ ft) distance from the measuring
cable end.
2. From the measuring module view, touch and hold the the unit you want to calibrate.
Select "Compass calibration" from the popup menu.
Operating instructions
61 - 003 - 15

The calibration wizard starts.
3. Familiarize yourself with the movement shown by the animation. Click Start when
you are ready to perform the movement for about 30 seconds.
4. Carry through the movement until the animation stops.
If the calibration wizard detects insufficient movement, the calibration is rejected.
Operating instructions
16 61 - 003 -

5.
When calibration is successfully completed, you'll see "Calibrated" message. You can
now close the calibration wizard.
4.3 Measurement settings
You can define the measurement settings in the Settings > Measurement settings view.
Measuring direction
A borehole can be measured either starting from the bottom or from the top.
Measurement point interval
Measuring cable marking interval in metres or feet (imperial cable).
Surface measurement point depth
Depending on the measuring direction, Surface measurement point depth defines the first
or last measurement depth.
Operating instructions
61 - 003 - 17

Measuring mode
The measuring mode can be defined under the Compass section:
•Gyro only for magnetic conditions. The Operator sets the collar heading for each hole.
The Gyro only mode is sensitive to correct working methods.
Note: Azimuth information on vertical and horizontal holes is limited.
•Magnetometer assisted gyro measurement to lower the magnetic influence. In this
mode, the shape of the borehole is measure with gyro, whereas the collar heading is
measured with magnetometer. The Magnetometer assisted gyro mode is sensitive to
correct working methods.
•Combination of gyro and magnetometer for best accuracy and most robust results.
Suitable for all hole directions.
4.4 Measuring view
The process of measuring a borehole is initiated in the measuring view. You can access
the measuring view with the Measure button in the home menu.
You can also access the measuring view by selecting the hole in the Site view and
clicking the Start measurement button.
4.4.1 Measuring a borehole from the bottom up
Procedure
1. Select Start new measurement to start the measuring process.
2. Lower the measurement probe into the borehole. Make sure that the probe touches
the bottom of the borehole.
Tip: To improve measurement accuracy, lift the measurement probe a
couple of centimeters from the bottom of the borehole.
Operating instructions
18 61 - 003 -

3. Press Begin lifting to start.
4. Enter the borehole length using the slider or the + and - buttons. If the current
borehole inclination is known, select Yes and enter the initial angle using the slider or
the + and - buttons.
5. Press Record to take the first measurement.
Note: Do not move the measurement probe when the measurement is
being recorded. Hold the measurement probe in place until the timer and
text on the display disappear.
Note: If the measurement probe is shaken during measurement, the timer
is reset and an alarm is sounded. In such case the system automatically
records the next measurement when the measurement probe is held still.
This feature identifies and rejects bad measurement data in real-time.
The system eventually accepts the measurement even if the
measurement probe was shaken.
Operating instructions
61 - 003 - 19

Once the measurement has been marked, the program returns to the measurement
view.
Note: If the bottom of the hole is not at full meters/feet, the second
timestamp is always taken at full meters/feet regardless of the
measurement interval. After the second timestamp, the chosen
measurement interval applies.
Example: Borehole length is 20.4 meters, and the measurement interval
is set to 2 m. The first measurement is taken at 20.4 m, the second at
20.0, after which the measurement locations are 18, 16, 14, 12, 10, 8, 6,
4, 2 and 1 meter (the last measurement is always taken at 1 m).
6. Start lifting the measurement probe out of the borehole. Mark the distance at the
preselected measurement intervals by pressing the Record button.
7. You can go back to the previous timestamp by pressing More...Rewind.
