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 Track Gauge, 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.
