it's analog. I guess the needle would fly off the chart if it was too much power.
Yes basically. If that happens, you just switch to a higher voltage. By the by, you're trying to measure voltage, not power. I kind of think of the voltage settings on multimeters as a 'zoom' function. If you use a smaller voltage setting, its like 'zooming in' on a smaller voltage. If the voltage you're measuring is bigger, you need to 'zoom out' by using a larger voltage.
Not a perfect analogy, but thats how i think of it hah.
Note, to measure the negative voltages, you'll have to put the ground lead on the -ve pad and the +ve lead goes on the 0 pad of the psu. Analog meters don't measure negative voltages.
Are the legs one the included power switch compatible with the legs on the phantom power switch? I want to assume that the two front legs on the pcb mount switch are just supports, am I right?
Alright... after reading this like ten times, i think i know what you mean. And yes, they are both DPDT switches. But i'm not sure what exactly you are referring to with the last sentance. By legs, do you mean the leads on the back of the switch?
