Скачать или смотреть Servicing and calibrating a Woelke ME104C Wow & Flutter meter

In this video I service a Woelke Magnetbandtechnik ME 104C wow and flutter meter. I explain how to use the device and go into an extensive explanation of how it works. Then I try to calibrate the device as accurate as possible.
I also go over the differences between the ME 104C, ME 102C, ME 102B and ME 101B.
