Diferent results of adjustment

Hi.

I'm having diferents results of adjustment with KH director. I'm using triton system. The same dosing parameters on 4 doses, and the same configuration of adjustment on KH director. But on chart appears diferents results of dosing. Why is the reason of this oscillations between the diferents dosing channels?

As long as the dosing schedules are identical and the KHD is told to control these same pumps, the adjusted amounts will be the same.

The only other cause would be from the pump calibration. Calibrate these dosing heads.
