The unit can give the operator the illusion of 'stopped motion' where in actuality the equipment under observation is in a moving state. By adjusting the flashing rate, equipment in motion appears to be standing still. With slight adjustment, movement can be viewed in apparent slow motion. Which enables the observer or the operator to study the process in action. Wide measuring range & high resolution. Digital display gives exact reading with no guessing or errors. Flash timer control conserves flash tube life. External trigger allows unit to be automatically synchronize with equipment. Strong flash light at low range and week flash light at high range to protect the flash tube.
