Pulse Measurement Error
You can use the DC measurement function to measure a pulse signal and obtain
its relevant average measurement quickly. The formula of the equivalent DC
average of a pulse signal is provided below.
where f(x) is the function representing the signal waveform over a period of T.
Errors may occur when the pulse signal is measured at low voltage range due to
saturation of the multimeter's analog-to-digital (ADC) rail voltage.
