Technics 1210 pitch problem

Technics 1210 pitch problem

Right I’ve bought some used mk2 1210’s and got them set up with traktor scratch,when I pitch downwards it works fine and goes down to -8% but when pitching up the bpm jumps up very quickly making it impossible to beatmatch. With the pitch set at +8% on the deck it shows that it’s actually increased to around +14% on traktor scratch. Can somebody please help me. Is it a problem with my decks or traktor. It does it on both my technics.

Just google 1200 pitch calibration, its pretty simple.
