Calibration for blasting machines and electronic detonators, in which a blasting machine or other calibration pulse signal source provides a calibration pulse to one or more electronic detonators with a pulse width that differs from a default expected value according to a scaling factor. Upon receipt, the electronic detonator counts a number of internal clock pulses while the calibration pulse is active, and stores the resulting calibration count value. Thereafter, in response to receiving a firing signal from the blasting machine, the electronic detonator counts a number of internal timer or clock pulses after receipt of a firing signal for initiating detonation, where the countdown value is computed according to the programmed delay time and the calibration count. The adjustable calibration pulse can be longer than the default expected value, allowing increased to the detonator countdown value to improve accuracy and scatter of the timing.
