Which terminals of the mm were the leads plugged into?
Which terminals of the mm were the leads plugged into?Testing out my new Craftsman 82141.

I decided to test voltage of an AC wall power adapter (for my dustbuster)
The little plug block says "Output 15V DC 200mA"
I set my Vdc to 20 and got a reading of 1.
I set my Vdc to 200 and got a reading of 24.2
If this AC adapter is supposed to be giving out 15V, how can the multimeter reading be so far off??
When there is no load on the adapter, you are measuring at the end of the plug that goes into the device (the Dustbuster) and is now otherwise loose, the voltage you measure may be somewhat higher than the stated output. Under normal operation of the device the voltage will be roughly as stated.Testing out my new Craftsman 82141.

Wait, this may be it.make sure you have ac and dc straight when measuring.
Your testing the output voltage of the device ... your output is DC not AC. You need the meter set to DC volts in the correct range. If the meter is auto ranging it will do this for you. Yours is not.My probes are plugged as follows:
Black = COM (middle)
Red = V.Ohm.mA (right)
Wait, this may be it.
I am testing a house current, so it should be AC.
I had it set on VDC-200 on the dial (upper left)
This is what gave me the 24V reading.
So, I need "VAC" on the upper right, yes?
However, when I put it to VAC-200, I get 0.00 (After briefly spiking to 8v for a second)
Does this make sense?
