Stop in for a cup of coffee

I have NEVER had any issues with harbor freight volt meters but today, this one is not registering anything.

I put it across the battery and it says 00.00 and the leads get hot.

I know the battery has juice, enough juice so it has to be the meter.

First time this happens to me and a shame it has to be a cute one with a little backlit screen :wtf::(:(
