What should the multimeter dial be set to when testing AC voltage?

DCV
Ohms
ACV
Continuity

The correct answer is: ACV

When testing AC voltage with a multimeter, the dial should be set to ACV, which stands for Alternating Current Voltage. This setting allows the multimeter to accurately measure the voltage of AC circuits, which is the standard type of electricity used in homes and many RV appliances. AC voltage is characterized by its ability to change direction periodically, and the ACV setting on the multimeter is specifically designed to read these fluctuating voltages. Using a different setting would lead to incorrect measurements. Setting the multimeter to DCV (Direct Current Voltage) would not provide accurate readings for AC voltage, as it is tuned for a different type of electrical current that flows in one direction. Setting it to Ohms would test for resistance rather than voltage, and the Continuity setting is used for checking whether a circuit is complete, not for measuring voltage. Therefore, the ACV setting is essential for correctly measuring AC voltage in various applications, including those commonly found in recreational vehicles.
