Flash tube It is required to change the Flash Duration Approximately 60 to 1,000 replacement flash tube when the microseconds. instrument start to flash Flash color Xenon white 6,500 K degree irregularly at speeds of 3600Flash energy 4 Watts-seconds (joules). RPM/FPM or more.Beam Angle 80 degrees. OPERATIONS  PROCEDURES Preparation (a) Plug unit into a properly grounded 110V AC, 220V AC or 230V AC outlet.(b) 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 in unison (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 type is AC 110V, or220 V  or 230V.
