Measuring AC Voltage
Set up your multimeter to measure AC voltage as shown in 
Figure  2- 2. Probe the test points and read the display.
Figure 2-1 AC voltage display
AC voltage measurements measured with this multimeter are returned as 
true rms (root mean square) readings. These readings are accurate for sine 
waves and other waveforms (with no DC offset) such as square waves, 
triangle waves, and staircase waves.
