Hello, there is a problem in my sign in for a ticket. I have a brand new ion director. I'm using it for 10 days. Every 2-3 measure it gives bad sensor performance fault. I empy cells reprepare cell and after two hours it measures with %87 sensor performance. Other day it measures %100 sensor performance and 1-2 days later bad sensor fault repeats.
I submerged referance fluids but it gets some thin air inline in a few days. I calibrated pumps and measured water sample line volume with scale. My pump connections are ok.
I'm also using profilux and Kh director without any problems.
