if you can set your cameras shutter speed and aperture, then you’ll have no trouble guessing the effective iso..
I use my meters this way though….
I set my camera up, and take a reading with my meter for whichever light source is my fill or ambient light.
I then use the lightmeter to calculate light ratios for any lights I add to the scene. (key light, rim lights, hair/kicker light etc.). I then use a greycard to set exposure and color on my camera. Iuse this method because I shoot stills and video, on every job, and that’s what works for me.
