Angle master wm 200

[numpty]

 New to forum and woodworking, plus using Clarkes 8"  wet wheel grinder Tormek unaffordable,, Aaaaah shame!, not all at once please.
ikely wrong place but here goes.
I recently purchased a Tormek Angle master wm-200 and it has two angle sales  one above the other , The lower scale is 10-75°  and upper scale mb-100  0-55°.
I am using the lower scale ready to sharpening both chisels and a plane blade.angle seems right.  No YouTube demo video or instructions on box refer to top scale.
Curiosity has the better of me what top scale is for. I think Have the right forum name.
Thanks in advance

It's for setting the angle using the MB-100... which is used to sharpen on the flat side of the diamond wheel.
