The 1531-P2 is a valuable asset to any stroboscopic or high-speed photographic application. The Flash Delay synchronizes the strobe with rapidly moving objects and controls the flash, relative to the position of the object; by introducing a variable time delay in the electrical path between the trigger source (transducer, contact, photocell, etc) and the strobe. In stroboscopic applications this delay allows you to position the stopped motion to any point of interest in the action. By the simple turn of a knob, you can reposition the image to illustrate a dozen, or even a hundred, points in order to analyze completely all aspects of the motion.

For photographic records, a single-flash mode is provided. Once the delay has been set so the image is positioned properly, the mode is set to Single Flash and the flash will then occur only when the camera shutter is re­leased and the action is in the proper position. This mode allows the brightest possible flash and eliminates blur.
