Overview

1. Overview
Congratulations on purchasing the LMX100 Ground Penetrating Radar (GPR) system. This
system is optimized for locating buried utilities. With a very simple menu and user-friendly
interface, you will be finding targets in minutes.
Features of the LMX100 include:
•High visibility, touch screen display
•UWB (ultra-wide band) Antenna producing highest data quality
•Lightweight fibreglass cart frame
•Built-in Wi-Fi capability
•Integrated GPS receiver for geo-referencing data
•Ability to draw arrows on the screen, to highlight objects
•Easy screen captures of data
This manual describes everything you need to assemble the system, change settings and start
scanning. There is also a section that describes the basics of GPR theory and techniques for
locating utilities.
This manual references embedded software version V1 R6. To see which software version is
installed on your system, see the Swipe Down menu in Section 3.4.
Online training videos for the LMX100 can be found on Sensors & Software’s website at:
https://www.sensoft.ca/training-events/training/lmx100-training-videos
(note: you will need to setup a login & password to access this)

2. Assembly
2.1 Out of the box
You will find the following components in your LMX100 box. Some of these may already be
assembled.
Attach the Cart Handle to Cart Base using the Handle Pins. Ensure the Display Unit Tray is
facing the operator.

Assembly
4
Attach the GPR Sensor to the Cart using the Sensor Support Straps. Ensure the Sensor is
oriented the correct way with the connections toward the back of the Cart. Using the Sensor
Support Straps, adjust the height of the Sensor so it is 1-2 cm (½ –¾ inch) above the ground.
The best way to get a uniform Sensor height is to place a couple of sheets of thick cardboard,
particle board or Styrofoam under the sensor before securing the Sensor Support Straps.
Attach the Display Unit onto the Display Unit Tray on the Cart. The Display unit slides down into
the tray, catching on both sides of the mount and is held in place with the pull pin. When a click
is heard, the Display Unit is firmly in place. Adjust the angle of the Display Unit by loosening the
hand-screws underneath the Display Unit Tray, rotating the Display Unit to the desired angle
and tightening the hand-screws. To remove the Display Unit, disconnect all cables, pull out the
pull pin and lift the Display Unit up.
Attach the Display Cable to the back of the Display Unit with the jackscrews. Connect the other
end of the cable to the Sensor. Ensure the cable is routed as shown below.

Assembly
5
Attach the Odometer and Battery Cables. The Odometer Cable connects to the closest
receptacle on the Sensor. Attach the Battery Cable to the Sensor and the Battery. The system
is now setup and ready to use.

2.2 Fully Assembled
The fully assembled LMX100 will look like the following. Simply reverse directions to
disassemble for transport.

3. Getting Started
3.1 Powering Up
When the battery is first plugged in, the LED goes green for 5 seconds then disappears.
To start the system, press the red power button on the display unit. The LED on the front panel
will light up red.
Figure 3-1: Display Unit
Once boot up is complete, the colour of the LED will indicate the amount of battery power
remaining:
•20% to 100% = green
•10% to 20% = orange
•0% to 10% = red
The first time you turn on the LMX100, you will need to configure the system (Figure 3-1). A
series of screen prompts will allow you to setup the language, units, date & time, and some
other options. You will have to do this again anytime you update the embedded software
(Section 10.6).
Every subsequent time the system boots up, you will see the main screen (Figure 3-2).

3.2 Shutting down
To power down, press the red power button on the display unit once. A confirmation message
will appear, after which you can press Yes to proceed. In the rare event that the display unit is
unresponsive, a hard shutdown can be done by pressing and holding the red power button until
the unit shuts down.
3.3 Interacting with the Display Unit
Data collection is controlled by the Display Unit. The Display Unit has embedded software to set
survey parameters and collect, display and store data.
The Display Unit offers touch screen operation, as well as a water-resistant membrane keypad
with a number of buttons that can be pressed to perform various tasks. Most operations can be
done using either the touch screen or the keypad.
Use the following table as a guide to working with the keypad on the Display Unit:
