Opemus 6 oblique rod numerical scale

[Henry Alive]

Hello to everybody. I am an enthusiast photographer new in this forum. I have an Opemus 6, and it works very well. However, I do not utilize the numerical scale located in the oblique rod, because I do not know how to work with. I know it helps to determine the exposure time in case of the change in the magnification ratio. Can you help me to understand it? Thank you.

Dear Henry,

A quick search found that a fellow on Photo.net gave you a link to a manual. Here is a link to the english version in case you didn't have that:

I would think that some measurment and the application of the inverse square rule would help you determine if you need new charts (I doubt you will) for the 6 vs 5.
