Principle Overview:

The basic testing principle of a digital millisecond timer is: the measured signal is attenuated, clipped, amplified, and shaped through the input channel to control the opening and closing of the main gate. Within the measured time, the counter counts the internal time standard, thereby displaying the numerical value of the measured time.
