Reveni Labs Camera Tester: New perspectives for professional and private camera repairers

I wonder if the light source is bright enough to work on large format graflex slr's with focal plane shutters, as well as speed graphics.
Currently I have a phocron, sadly no longer made. I have made a rig for the light source for this, so it can be inserted into the camera close to the meter. It's the best device I've seen yet. But always willing to step up

How does the sensitivity setting affects leaf shutter testing results? Mine was initially at 4 and gave results out of expectation, like 1/50 instead of 1/60 and 1/90 instead of 1/125, repeatedly. When I set the sensitivity to 2, results match and are only slightly off. I wonder now which of the different results is the (most) correct one?
Best,

I would assume it to be the one which gives maximum signal-to-noise without clipping (i.e. flat-topped peaks).

Thanks. Some auto-range would be cool then, otherwise the best signal to noise ratio is hard to see as one expects a flat top when fully open...?

Besides the LF lenses, I also have a bunch of Hasselblad V lenses for testing. What is the best way to do this? With body, without? Any pitfalls?

Thanks,

I did mine attached to the body. Much quicker and easier than trying to manually trip and recock the shutters, especially if you're taking multiple readings and averaging. The only thing to be aware of is the sensor cable may not be long enough to do this with some of the larger tele lenses. With my 250 SA there was just enough cable length to do it.

You can use a straight-through RS232 extension cable (ideally 3ft or shorter) to get more length. https://www.amazon.com/Serial-Extension-Female-Straight-Through/dp/B08SMC98LB/
