Making Measurements
Measuring frequency
Frequency is the number of cycles a signal completes each second. Frequency is
defined as 1/Period. Period is defined as the time between the middle threshold
crossings of two consecutive, like-polarity edges, as shown in
The multimeter measures the frequency of a voltage or current signal by counting
the number of times the signal crosses a threshold level within a specified period
of time.
