Sažetak
The velocity of detonation is one of basic parameters for determination of explosive power and quality that can be measured. Delay period is of the same importance for detonators and other initiation devices. Determination of those parameters is mainly performed by optical- electrical method by time interval measurement. In Laboratory for testing of explosive material, a method was developed for the calibration of electronic timer with photodiodes and digital oscilloscope. Calibration of electronic timer, velocity of detonation measuring device, is carried out by parallel measuring of a time interval by a digital oscilloscope. Paper describes the setup and measurement conditions, type of instrumentation and accessories of comparison calibration method with review according to the measuring uncertainty and method suitability.
