4.0 Getting Started
4.1 Overview
The ABT8000 is a light-weight gauge that allows the user to safely take Height and Stagger
measurements of the OHL (Over Head Line) using laser technology as well as the ability to log and
store data directly to an android device. The ABT8000 also features a built in display which can
show the recorded readings and a downloadable application for smart phones. This application is
able to connect to the gauge using wireless technology and can save post processing time back at
the office. The gauge can additionally measure Super-Elevation (SE), Rail Edge to Face of Structure
(REFOS), temperature and GPS location.
The built-in laser unit is positioned at eye-level and features a 90º view finder with a red LED guide
dot, enabling the operator to easily set the laser location marker onto the OHL in all weather
conditions including bright sunshine.
The ABT8000 also features a removable REFOS laser unit which can be attached magnetically to
either foot of the gauge and can be controlled via controls on the vertical beam or the smart phone
application.
The vertical beam folds down flat to the horizontal beam for storage and transport.

b. There are two additional buttons below the button, these are the M(OHL Laser
height measurements, Stagger readings) and R(REFOS measurement Left/Right).
The readings taken in standalone mode (without use of App) are not saved in the
DLHS. The user will need to document these readings manually.
4.4 Measuring Height & Stagger
1. Ensure vertical beam is in the operating position.
2. Press ‘M’ to turn on the measurement laser. The laser will stay turned on for 1 minute and
during this time the user can position the DLHS gauge to the measurement location.
3. Look through the view finder on the vertical beam to view a red LED guide dot (shown in
Figure 5). This will assist the user in aligning the measurement laser with the OHL.
4. The vertical beam can be moved from side to side by turning the stagger adjustment wheel
located in the centre of the vertical beam (shown in figure 6). Adjust the vertical beam until
the red LED guide dot is on the OHL, press ‘M’ again to record the stagger measurement
which will be displayed on the screen of the DLHS gauge.

4.5 Measuring Cant/ Super Elevation & Track Gauge
1. The Cant / SE and Track Gauge are measured automatically when an OHL stagger
measurement is made following the instructions in Section 4.4. The measurements will
appear on the screen of the DLHS gauge.
A positive SE reading is when the right rail is higher than the left.
4.6 Measuring REFOS
1. Secure the REFOS laser unit supplied with the DLHS carefully to the connector slots on
either foot of the gauge. The laser unit is powered by the DLHS batteries. (See Figure 3).
2. Use the spirit level on the laser unit to ensure it is level after placing the gauge in a position
to take the reading.

5.0 Maintenance
5.1 User Advice
Check that the bearing surfaces that are in contact with the rail are clean and can move
freely
Ensure that the vertical beam locks firmly into place and there is no slack.
Ensure the laser window on the vertical beam and the REFOS laser unit are clear.
5.2 Every 3 Months
Visually check for damage
Ensure the vertical beam moves smoothly across the cross beam using the stagger
adjustment wheel.
5.3 Annual
To ensure the ongoing accuracy of your ABT8100, the gauge should be calibrated every
12 months. For UK users this means returning to Abtus for re-calibration and for overseas
users this means returning to your local Abtus Representative, a list of which can be found
on www.abtus.com.

6.0 Trouble Shooter
6.1 Readings are not showing or incorrect
Ensure the batteries are fully charged.
Restart the gauge and reconnect the DLHS to the app. Ensure the ‘Connected’ message
appears when pressing the ‘Connect’ button.
The ‘Measure’button has to be pressed twice to get a reading; first press to turn on the
laser and second press to measure the distance. The user must wait at least 1 second
between the presses to allow the laser enough time to receive a reading and display it on
the screen.
Pressing the ‘Measure’button three times rapidly will cause the DLHS to show an error
message on the readings. Please allow enough time for the device to measure and send
the reading to the display before starting a new recording.
6.2 GPS readings are not showing or inaccurate
After a cold start, the GPS unit requires roughly 1 minute to locate the satellites and
provide an initial GPS reading. This delay should only happen on the first recording,
subsequent readings shouldn’t have any delays in providing accurate GPS coordinates.
Certain areas on the track and conditions can affect the readings provided by the GPS,
including signal obstructions caused by tunnels, buildings, trees or even lack of satellites.
