Dougdeacon, thanks that is something I have not thought about. I have confirmed on my el cheapo digital force gauge that it does measure the correct weight despite the attractive force by zeroing with the cartridge on the platform, and then lifting the cartridge away, and it gives the exact negative reading of the force I set in the first place. The magnets on my Lyra are unbelievably strong and I'm sure the force on the suspension during measurement is not good for the suspension...finally a reason to never measure with a gauge that is magnetic, and a compelling one!!
