GL300 MUTECH/Contelec Hollow shaft Test

GL300 MUTECH Hollow shaft test. This product is much cheaper and similar to Swiss made Contelec product. This pot is mostly used in Goller mercerizing machines all over the world.
In this videos a test is demonstrated on pot/Angular position sensor to make sure if it's a good working pot. We call this test as sine wave test, because the end waveform looks much like a sine wave.
