RPM/FPM or more. Beam angle 80 operating duty for prolong life and safe operation Please Adhere To The Following Duty Cycle: Cycle Below 1,000 RPM - 30 Minutes. Above 3,600 RPM - 5 Minutes Always allow a 10 minute cooling off period between cycles Operations Procedures: Preparation: Plug unit into a properly grounded 110V AC, 220V AC or 230V AC outlet Turn the power switch to "on" position.(c) Determine the range switch to "Low" or "High" position Checking Speed: When checking speed, care must be taken to insure that the strobe is flashing inunison (one to one) with the object being monitored. A Stroboscope will also stop motion at 2:1, 3:1, 4:1 et., this is normally referred to as harmonies. To be sure of unison, turn the dial until two images appear - this will double the actual speed. Then lower the flashing rate until a single and stationary image appears -this is the actual true speed. Checking Motion For Motion Analysis: Simply locate the actual speed as mentioned above and then turn the dial slowly up or down. This will give a slow motion effect allowing complete inspection Remark : When order the stroboscope, should inform the power supply types which is is AC 110 V, 220 V or 230 V.* Appearance and specifications listed in this brochure are subject to change without notice.
