It is required to change the flash tube when the instrument start to flash irregularly at speeds of 3600 RPM/FPM or more.操作程序 OPERATIONS PROCEDURES
準備 (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.檢查速度 (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.檢查動作 (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.
