Why you have to adjust them???

I need to adjust them because the old trimpots have deteriotated contacts and the sound was very noisey and output sound goes on/off. I have replaced the old ones with new sealed trimpots. I measured the old trimpots with a multimeter, extreme point to center and center to extreme point then I need to create the same value in the new trimpots with the help of the multimeter. Now the amplifier is in function and no noise cames out, however I think that procedure is not correct.
Thank you very much for your reply.
Bye Leo.
