Hello Herbert,
My fault, the Dot marker can be positioned by the Dot marker control and is not always centered on screen.?
But this makes no difference as you see that the dot and it is not aligned to the DC-peak.?
If I get this correctly, the adjustment is described in the manual in step 3 of calibration and adjustment procedure.?
These pots are under the cover of the board on the right side. You will probably need 2 plug-in extenders for this adjustment (that is the reason, why I didn¡¯t fix my 7L5 units yet). I wouldn¡¯t recommend doing this in place inside a scope.?
Besides: According to the manual, your calibrator is out of spec. I would trust the HP counter too¡
Regards,
Gerrit
