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 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.
