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 Advice > ή 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 this instrument are electronically stored and can be recalled at any time. Upon delivery, the instrument complies with the required safety regulations. To maintain...

3.1 SIGNAL MAINS PUSHBUTTON "ON" (5) switches on the stroboscope by depressing the pushbutton. When depressed (red signal), the instrument is ready to work. 3.2 SIGNAL FLASH FREQUENCY RANGE SELECTOR PUSHBUTTONS (8) for selection of desired flash rate range: > PUSH BUTTON FLASHES/MIN = RPM FLASHES/SEC = HZ 8.1 - low range 150 - 4000 2.5 - 66.67 8.2 - medium range 3700 - 18000 61.67 - 300 8.3 - max. range 18000 - 60000 300 - 1000 When changing over from one range into the next the previously pressed button will automatically be released. The range selector pushbutton shows colour green when...

SIGNAL PUSHBUTTON for EXTERNAL CONTROL "Ext Trig." (9) serves to select the desired mode of synchronization. When the flash frequency is to be controlled by an external source via "Trigger Input" (4) the round signal pustbutton has to be depressed (signal indication: red). The flash rate can be adjusted by means of the Control Knob with Dial (3) within the preselected range (8) when the pushbutton is not pressed (signal indication: grey). Switching over to other operating mode the round pushbutton will automatically be released 3.7 SIGNAL PUSHBUTTON for LINE SYNCHRONIZATION ( 7 ) If the...

Operation with External Control If the flash rate is to be controlled externally by closing a contact, magnetic impulses, light impulses or other pulse signals pustbutton 5. "Ext.Trig." (9) must be pushed in "ON" position (signal indicating red). Connection of the pulse generator to the control unit is to be effected through a trigger cable which must be connected to the "Trigger Input" (4) . Select the proper frequency range ( pushbuttons 8ē ) in which the external synchronizing frequency presumably takes place. If the control impulse frequency exceeds the selected range the next higher...

2e between two succeeding flashes. If /e/ is sufficiently small the eye perceives a constant slow-motion cycle. Angular speed w , at which the object appears to rotate, is given by: wҒ = 2 v = 2 ҏ e = 2 e 2 e T (n+e) r nr If we compare this with the true angular speed of the object, we obtain: w = (e 緷 n ) > 畕Օ w For e > 0 (i.e. T > Tn and/or f > fn ) w and w have the same sign, so that true and apparent rotation are in the same direction. The opposite holds for e < 0 . With increasing /e/ the angular speed wҒ of the apparent rotation rises. Finally the angle 2 ππππ e becomes so large that...

Do not use the flash bulb needlessly, as its life is limited to approx. 350 hrs. You will achieve a much longer lifetime, if you switch the instrument off in cases of long intervals in between the measuring or motion control actions. When the lid catch of the housing is removed, the fuse 0.5 A (in case of 110V AC = 0.63 A) can easily be replaced. > If the instrument is suspected of being unsafe, take it out of operation permanently. This is usually the case when the unit shows physical demage, no sign of functioning or stress beyond the tolerable limits. Repair, replacing parts, calibration...
