SUMMARY
When connecting a Digital Multimeter (DMM) across a 120V peak AC signal in DC mode, the output should read zero volts. This is due to the fact that the average value of a sine wave is zero, which is a fundamental principle in AC signal measurement. Users confirmed that a DMM set to DC mode will not register any voltage from a pure AC signal, reinforcing the importance of understanding the measurement modes of DMMs.
