Calibration of the TLT-44 

To calibrate TLT-44 it must be assembled. Figure 20 shows the bar placed under the front 

wheels of the vehicle to be measured. Since the bar rests near the front wheels, it is tilted 

the same amount as the vehicle. The compensation procedure that follows corrects for the 

tilt. After assembly, the bar is calibrated according to the following procedure on the 

following page.
