By pressing the unit key ( UNIT ) it is also possible to set the phase displacement as a time delaybetween the trigger flank and flash. The previously displayed phase angle is subsequently convertedinto a time. The delay time can be set from 0.000 ms to 1000.00 ms. After changing to the unit " > "previously set phase angle is redisplayed. > The absolute zero of the phase adjuster can be adjusted by replacing " MOV " with " SET " in theMenue. The display subsequently has the following structure, for example in the PHASE mode: SL212.00 The absolute zero can now be set. All angles entered...

All current settings such as triggering or numerical values of the device can be stored by selecting themenue item STORE ( by pressing the mode key ). These are the standard settings when the device isswitched on. In addition, the mode which was active before storage is automatically active when thedevice is switched on. > -.3 +12V DC across 150 K Ω for switching contact - 4 Input ( 0.5 - 50V, R = 50 K Ω ) - 5 Signal ground- The connection of an external transmitter takes place via a seven pole diode plug with bayonet lock.-.The socket pin assignment for external triggering and synchronous...

If the rotating object (or the mark) is to appear to the observer as a stopped image under stroboscopiclight, the period T of the flash frequency must be a whole-number multiple n of the rotation period r : T = Tn = nr For the corresponding frequencies f = 1/T and revolutions v = 1/r the relationship is: f = fn = 1 v 緷 n The highest flash frequency (n = 1) which produces a stopped image of the object, i.e. the markequals the revolutions: f1 = v (stopped images in which the mark appears more than once stillresult from flash frequency f > f1 ).The observed phase of the rotation in stopped...

Stopped images of rotating objects results from flash frequency periods Tn = nr , and also at other flashfrequencies. However, the latter represent phantom objects, not the real object. Using the example of the rotating discwith an eccentric mark , it is obvious that stopped images also occur when: T = ( n 緷 k ) r and / or f = ( k 緷 n ) v, whereby n and k are whole relatively-prime numbers. The stopped image shows k marks, which are arrangedin the corner of a regular k -angle. Only a very few of the theoretically infinite number of flash frequencies resultin observable images, since at each...
