    I’m testing 120vac outlet. But it’s showing around 13vac. Why?
    Thanks

    Do you have both sampling settings on auto? As we can set those ourself, it is easy to set rates that are unusable for calculating rms voltages.

    You could also check buffer mode graph. You should see sinewave there, or some indication what the meter is actually seeing and what has happened.

    Sample rate 32
    Buffer 125
    If I go to graphic. I can see the chart with incorrect value

    Default for ac is 4000 Hz and 256 samples. Select those directly or leave it to auto. Even the DC defaults are higher than yours, at 125 Hz and 64 samples

    I tried with DC voltage and it is correct.
