We are using Insitec in our plant. We got a problem on the Insitec measurement. The powder flow is not consistent, so with the same motive air pressure, we get error messages of low signal or signal saturation. This means sometimes not enough powder, sometimes too much of it. I tried different nozzles on the J-tube and different sample position. What should I do?

I heard I can change the "Gain" which might help. Now the gain is X2. Should I increase it or decrease it? What does it mean? ■
