Metering for H-values on Rodenstock Imagon 250

[raucousimages]

I have a 250 Imagon in Copal 3. The H values on the discs are 5.8, 7.7, 9.5. 11.5. Do I meter for them as if they were F stops? I.E, F 5.8, 7.7, 9.5 and 11.5. That works out to somthing like F5.6 1/8, 8, 8 3/4 and 11 1/2

I also found a Copal 250mm F stop scale for a #3. I put it on and use it like a normal lens. It is very accurate and I like the look stoped way down. I just want to know if I am metering for the discs correctly.

Thanks John
