AC Voltage Measurements AC Voltage measurements are commonly used on automobiles when measuring items like wheel speed sensor output, crankshaft position sensor output, camshaft sensor output, distributor pickup coil output, and etc. To measure AC voltage you must place the selector switch in the AC volt position as shown above. The V with the wavy line above it represents AC voltage. The wavy line represents a sine wave, the most common AC voltage waveform on the planet. If the Hertz (Hz) button is pressed once while measuring AC voltage, the frequency of the AC voltage cycle will be displayed. The frequency range is from 0.01 Hz to 200 kHz. If the Hertz (Hz) button is pressed twice while measuring AC voltage, the percentage of time the voltage is positive during the AC voltage cycle will be displayed. If the sound wave button is pressed once while measuring the percentage of time the voltage is positive, the percentage of time the voltage is negative during the AC voltage cycle will be displayed instead.
