Accurate detonation time setting method for timed detonator has required delay time defined by given number of oscillations of quartz oscillator

摘要

The detonation time setting method has the delay interval defined by a given number of oscillations of a quartz oscillator, with the number of quartz oscillations over a timed interval at a given temperature, e.g. 25 degrees C, determined as the base measure for selecting the number of oscillations corresponding to the required delay interval.
