[QUOTE="Pdvdh, post: 523180, member: 4191"] That topic is discussed in the Thread I provided the link to - above. The only way to calibrate a chronograph is to have additional chronographs or test equipment that is also capable of recording velocity, and shoot over the other equipment at the same time you shoot over your chronograph. The calibration would involve increasing or decreasing the spacing of the skyscreens until the chronograph is reading consistent with the other units. Now if the Oehler company/folks would allow us to take our chronographs to their facility for testing along side of some of their premo units, adjustment of our skyscreens to calibrate our chronograph data to their data would be straightforward. But chronographs come in varying quality, like every other manufactured electronic product. And even the good ones can break, malfunction, or provide some false data even when they're in tip-top shape. Which is why you need at least two units in order to identify the bad data that crops up every now and then, from the good data that is normally received with a quality chronograph that's being operated properly. My 2 cents. [/QUOTE]
