While testing, you'd better use an adapter cap for the shooting caliber, so as to avert mistaken shooting to the panel. Please do not use it in the outdoor conditions of rain or heavy dusts, the device might be damaged and make an inaccurate testing. Please avert: testing of kinetic energy above 100J, or if a high kinetic energy bumps into the caliber. Self-test display C10/20/30, C11/21/31, one of them is not OK(ERROR), sensors need to be cleaned before test. Package List: 1 * Chronoscope 1 * Manual Package List: 1 * Chronoscope 1 * Manual
