Firstly, the vehicle is prepared: this includes placing it on the properly set up lamp workstation , the connecting of a battery charger and also the visual and functional test.
The beamsetter is then aligned to the vehicle.
With the SEG IV the device is optimally positioned to each individual light source with the aid of the laser pointer (for double lamps, repositioning is necessary in each case for low beam/high beam).
The required forward inclination can be seen on the B-pillar of the Mercedes W212. In the example, this is 1%.
On the SEG IV, the forward inclination read in this way is set accordingly using the rotary control knob. With the SEG V, the forward inclination is automatically taken over by the device during vehicle selection.
This is followed by the initiation of the actual light measurement, firstly of the low beam.
The result of the low beam can be read off the analogue scale on the SEG IV.
With the SEG V the result is displayed digitally. In the example, the light distribution is OK in each case.
The high beam measurement is then carried out accordingly. The results of the example measurements are also OK in every case.
In our example measurements shown above, the results were error-free. But how do results that deviate from the standard value present themselves? Here we provide an overview based on the low beam measurement with the SEG IV.
