True RMS reading meter or why do I get such high reading on AC functions?

We had a discussion on meter reading and power measurements. In a DC circuit it is really cut and dry. You just connect a meter and read the DC value. In an AC circuit it can become more complicated because the signal is not a true sin wave and because it may have a DC component. To address these issues I chose to display a couple of pages from the Fluke true RMS meter manual.

So taking a look at this info could take some confusion out of the interpretation of the readings.
