After a recent change in vapor production from my standard Ego battery, I want to check to see if the voltage being produced from my battery is right around where it should be. The only problem is, I don't exactly know what setting or the proper technique to use this thing without destroying my battery or getting an inaccurate reading.

This is a picture of the exact MultiMeter I am using. Any help would be much appreciate! Keep in mind I am a noob, so all instructions would be awesome!
Thanks, Tyler
