Jun 12, 2019 #1 BSB78 Chemical Joined Jun 12, 2019 Messages 1 Location US I have a inline weigh scale producing a “rectangular wave” output for weight over time... I am confident the product is not actually changing weight like this. The bandwidth of the waves is generally 3.5-5 minutes. What can possibly be causing this?
