Measuring AC Voltage
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 wave forms
(with no DC offset) such as square waves, triangle waves,
and staircase waves.
For measuring AC voltage signals with DC offset (U1272A
only), refer to the “Measuring AC and DC Signals (U1272A
only)” section later in this manual.
1 Rotate the multimeter’s rotary switch to /
(or / , U1272A only).
2 Set up your multimeter to measure AC voltage as shown
in Figure 2- 2.
3 Probe the test points and read the display.
