HW-40 Black Edition

[jerryb]

Hi

I own a HW 40 ser# 25. I tested my speed with the RPM app on my cell phone. The results show the speed as slightly slow at 33RPM. I have checked multiple times and the result is always the same.

Is there any way to adjust?

Regards

Jerry

Jery, I would contact VPI direct and they might be able to help.

I have read of the RPM app being slightly off in some cases, I use a KAB strobe disc for what I believe to be the best accuracy.
