I agree, I looked through it (Lunasix 3) also and saw no true mention on measuring "EV". The Luna-Pro F manual suggests a setting of ISO 50 and Incident mode as the methodology for EV measurement. They further caution that the Luna-Pro F "cannot be used as a precision luxmeter" due to the spherical vs. flat incident surface.

If I learned anything in the last 10 days, it is that any given light meter with an EV scale should be heavily referenced in the EV technique before stepping into that realm. I think most meters are specific with their own methods.
