Projector Electrical Project Problem.

[Nataku]

I'm working on a project involving my projector, what I need to know is if the lamp is being powered by AC or DC, and by how much...

Here's the situation, I fire up the projector without the lamp installed, set my Multimeter to AC, and stick the probes in the power connections for the lamp. The meter reads 0 Vac, so I pull out the probes, switch it to DC and try again. This time it reads 7.97Vdc.

but, As I reach across the table to write the number down (about 5 seconds later) I here POP POP POP POP coming from the multimeter. I yank out the the probes to make it stop.

I take apart my multimeter to inspect the damage to find this


So my question is, what the hell happened?!

P.S. the fuse in the multimeter is NOT blown.

Well......... time for the new Fluke multimeter

Anyway what's model of the multimeter is it?
And judging from the burn pattern i would say that the selector wheel was improperly set and it was stuck between two voltage setting......... sometimes vibration may move the selector wheel and giddy-yup, everything fried

A little 25$ Craftsman Multimeter. I wish I could afford a Fluke,

Here is the thing, Based on the location of the burns, The selector wheel wasn't touching that part at the time.
