Snap-On QC2FR75 calibratrion

[540i6]

I bought a very nice Digital Torque Adaptor to verify/calibrate my torque wrenches. I already went through all of them, some were right on the mark, some needed adjustment. This QC2FR75 is just a bit under and I want to adjust it, but not sure how it's done with this wrench. I removed the end cap on the handle and there is a nut behind it, but it doesn't seem that the nut is for the actual adjustment, but rather holds the assembly together. I don't want to damage anything or take apart the wrench unless it's necessary. Does anyone know how to properly adjust the wrench? Thanks!

Bump.

For me I would send it in to any number of companies that offer recalibration. Not something that most people have the tools to adjust properly.

that looks like an adjustor since the nut is marked with wax that shows if it has moved

I don't know anything about adjusting torque wrenches but I would say the nut is for adjusting for two reasons, one being that it also has a snap ring to hold parts together and two being that the nut is marked to tell if it moves.
