It doesnt matter if you are a beginner or pro in the multimeter field. Continue with Recommended Cookies. To measure AC voltage using a benchtop multimeter, select the "AC V" mode and connect your probes. Rotate selector to AC or DC voltage. If you are enthusiastic enough about doing your electrical works by yourself, then select a high-quality multimeter for your daily life use. A multimeter is a convenient device used to measure voltage, electricity, resistance, etc. Measurements above and below the reference value are displayed. You need to consider that if you measure the A/C voltage at different times, the result will also vary. Depending on the model you purchase, the display could have an option of remaining light even in the dark. Then turn on the multimeter, set the energy at the highest range, and dial the correct position. The following Arduino code measures the RMS value of the input AC voltage by detecting the maximum value of the half wave and then divide it by square root of 2 (2). 2.
