This is the new Multimeter as seen in the photo I picked up.
I have a lot of AC adapters I need to test.
Can Anyone walk me through this?
Either this Multimeter is fucked or I need to go back to grade school.
>>938487
plug the adapter into a power socket
set the meter to dc
red touch outer
black touch inside
read meter
done
>>938490
There is a 'DC' setting on each main setting by pressing 'select' ie: mA has a 'DC' setting as does V.
What one should I be selecting?
>>938494
test both
you should be getting 9v and 300mA from the label of your adapter, you need to see if they are correct, so do both and see both numbers
>>938495
Testing current that way would be a dead short...
Also it might not necessarily read exactly 9v, some power lumps need to have a load connected to output the correct voltage.
OP here.
Thanks for clearing that up.
No luck with the original one pictured but I am now testing a dc 9V adapter and it is consistently reading higher around 18.63. Is this normal or something to be concerned about?
>>938511
it is normal if the meter is working
>>938514
Even if the wall adapter is unregulated?

if only there was some kind of manual, that the owner of the DMM could use to figure out how to do this... an "owners manual" if you will.

If only DIY would step up and answer basic questions.
>>938593
that's what the manual is for.

That will teach you what you need to know about multimeters.
