For this application, beside an extensive function test with torque measurement also an evaluation by means of a camera is integrated. With it, the single segments may be checked on a LCD-screen in relation with different functions. If, e.g. the DCF77-time transmitter is activated, it is checked, if the antenna symbol is displayed on the LCD-screen.
The belt winder is equipped with up to 10 operating buttons which are activated by the tester by freely-programmable miniature cylinders. The tester is able to simulate all the functions the end user carries out later.
