I mistakenly left my digital multimeter on DC when i went to test a wall outlet, and it threw a spark and charred the tips of my multimeter. I had always been told it would not do such a thing, even on the wrong setting. However, I am now timid to recheck the outlet on the AC setting. So, I used a outlet plug light indicator and it said everything was kosher with the outlet. Can anyone tell me why the spark?
