GTI Geomaster is a computer aligner for vehicles of up to 3,5 ton gvw and with wheel rims ranging from 12" to 20".
GTI Geomaster comes in three options, all of which use the same software:
GTI Standard | GTI Specjal | GTI Radio |
GTI Geomaster makes easy measuring the geometry of wheels and chassis in passenger cars, minivans and also lcv's, with wheel rim diameter ranging from 12" to 22". The machine has four measuring units with altogether eight potentiometric sensors. It can also be used, however, as a two-unit device, where two front measuring units are used for measurements with reference to the axis of symmetry.
The whole measurement process is done by computer software and can be followed on the LCD display. There is the option of four-point run-out compensation, which means that any rim deformation or imprecisely mounted clamps will not affect the result of the measurement. Further, the option to use a quick-clamping type of clamps means that run-out compensation can, in some cases, be skipped altogether. GTI Geomaster is compatible with electronic and mechanical turntables alike.
GTI Geomaster's main assets:
GTI Geomaster is a computer aligner for vehicles of up to 3,5 ton gvw and with wheel rims ranging from 12" to 20". The use of computer and sensors with increased accuracy means that the measurement results are very precise and repeatable. The aligner can be used to check passenger cars, minibuses as well as lcv's.
GTI,thanks to its universal accessories, can be used in any kind of garage or repair centre. All that is needed is a hard, level floor and, optionally, an inspection pit (for making adjustments to the car) or a lift (four-post or scissor type).

The device has a function that is called "Quick overhaul", which allows the technician to make a superficial assessment of the vehicle's condition, without having to go through the actual automatic measurement. This, however, is only a rough measurement that does not contain all the parameters. If a specific car model has been selected, the measured values are displayed in colours that suggest their correctness or incorrectness in comparison to that model's factory default settings.

GTI has advanced operating software that makes it possible to measure additional parameters (e.g. the so-called panel-beater measurement). This, in turn,gives the technician complete and comprehensive information on how the individual suspension components are positioned with respect to one another.
GTI Geomaster measures the following parameters:
|
Notes: (*) - only with four measuring units (**) - only with electronic turntables |
The function "rear axle angles adjustment" allows the technician to simultaneously observe and adjust the toe, half-toe and camber angles for each wheel. It is also possible to go on from here to adjusting camber angles on a raised vehicle.
The function "front wheel vertical angles adjustment" allows the technician to simultaneously observe and adjust the toe, half-toe and cater angles. Here, it is also possible to move on to adjusting camber on a raised vehicle. |
The measurement process in GTI Geomaster makes use of specialist electronic sensors. For the measurement of horizontal angles, the sensors are connected with elastic cables; the vertical angles are measured with opto-electronic gravitational sensors.
The measured values are displayed directly on the computer screen. Run-out compensation of the clamp-wheel arrangement is a four-point one, which eliminates any errors there may be that result from deformation of the wheel rims or inacurate clamp mounting. The computer software may run in an automated mode, prompting the technician with commands in a step-by-step fashion, or the technician can choose only the functions he wants.
The aligner can be operated using the computer keyboard or the remote control and, when going through run-out compensation, by means of the buttons in the measuring units.

Each measurement report can be printed in an unlimited number of copies. The report includes the factory-recommended angle values, the initially measured values and the final measurement report - after the adjustments have been made. The values that are different from those recommended by the manufacturer are highlighted.
