Introduction Each MOVISTROB® product has to pass through various controls during its production phases and must also undergo very strict and conscientious function and quality tests before leaving the factory for delivery to our clients. We can assure you that the MOVISTROB® product you received is in strict conformity with our high quality standards and it fully meets all safety and performance requirements. All relevant data on...

The previously displayed phase angle is subsequently converted into a time. The delay time can be set from 0.000 ms to 1000.00 ms. After changing to the unit " 0 " previously set phase angle is redisplayed. 5.2.2 Absolute Zero Setting The absolute zero of the phase adjuster can...

Storing all Settings in STORE Mode All current settings such as triggering or numerical values of the device can be stored by selecting the menue item STORE ( by pressing the mode key ). These are the standard settings when the device is switched on. In addition, the mode which was active before...

Using the example of the rotating dise with an eccentric mark , it is obvious that stopped images also occur when: T=(n■*■ k ) r and / or f = ( k ■*■ n ) v, whereby n and k are whole relatively-prime numbers. The stopped image shows k marks, which are arranged in the corner of a regular k-angle. Only a very few of the theoretically infinite number of flash frequencies...
