WebJul 5, 2024 · Select the “AC voltage” mode by turning the tester knob. The meter will only measure the AC component of the signal, the ripple voltage, if present. The display shows the measured value of the ripple voltage amplitude. If it shows the value 0.00 mV it means that, most likely, the ripple is absent. WebPick the AC voltage by twisting the dial on the front to the symbol of an oscillatory wave. Make sure you connect the probes on the circuit with the ripple voltage. Your meter will measure the signal’s AC component. The display must change to present the measured value of the ripple voltage amplitude. Ensure you also measure the frequency.
WebOccasionally, using an AC “filter” is the easiest way to get a usable alternator ripple pattern. The filter simply screens out DC voltage so the scope displays only whatever AC voltage is present. I captured the … WebJun 17, 2016 · The best way to measure ripple in a boost converter using an oscilloscope is to connect a probe to the output and feed it into one of your analog channel inputs.
