Title :
A Crystal and a Single Chip Measures Relay´s Turn-On and Turn-Off Time in Microseconds
Abstract :
A simple circuit is described which can measure turn-on and turn-off time of any relay in microseconds. This circuit could be used to measure the accuracies of timers, and with slight modifications could be used to measure delays between any two events.
