Hofmann Geodyna 2100 steel wheels were not able to balance

Hello, have me a Hofman Geodyna 2100 built year 1996 increased, as far as everything paletti happens when I balance aluminum rims to measure this faultless rims to measure data enter weights are displayed then glued test run and 2x ok. BUT with steel rims clearly first from ́ ́ ́ALU ́ ́ to ́ ́ ́NORMAL ́ ́ program set then enter data again and then the weights are shown to me this I then also axial strike but then at the control rotation she still wants to m very weights have attached to a completely different place and if I also bring this what you don’t actually do even then it’s not enough and so it goes on forever so I can do what I want with steel rims I never get this on NULL??? To info Calibrated I got it right before!! Hope this was right so let c14 turn then turn the kalibrie weight on it and wait until this dumpling sounds??? What can I still do n I don’t understand it quite as yes alufelgen perfectly funkionieren…Bin echlich über jeden info zusammenbar mfg Thomas K. aus H.
