What is the principle of measurement of Dutycycle in a Digital Handheld multimeter?
I have noticed, in some multimeters, the duty cycle measurement is very sensitive to the input signal amplitude. The reading go mad if the signal amplitude is more than say 4V (it shows 99%, where the actual duty cycle is 30%). It was a brand new meter purchased through Amazon. I tried two nos - same result.
Someone, please suggest a method to solve this problem.
