I just finally got the second axis of my DRO-350 operational tonight. The only thing is the display jitters badly. I read through the operator's manual but couldn't find a solution. I tried to adjust the Filter Threshold, but my DRO won't allow me to imput a numerical value. I can only choose from: ST, Lo, Hi, and No. Please help! I'm so close to getting this all together and I'm sure there is someone out there that can help me figure this out. Thanks in advance!
