I would suggest 2 methods.

As Christer says, if you're outdoors, you can use pavement or grass as a substitute for a gray card reading. I have found, however, that the M8 meter correctly meters just about all the time, outdoors. It prefers to meter the sky, so if you want lower levels, either adjust manually, or meter your hand.

For shots where people are included, meter your hand or meter a face if you can get there.

I have shot about 1500 pix, now, with the M8, using 24, 35, 50, and 75mm lenses. The M8 meters correctly when not himdered. As an example where manual setting are required: I shoot stage productions, so I find the correct manual speed and aperture settings using the review screen.
