Process
calibration
The following must be considered before starting calibration:

Drain the measuring chamber and clean it if necessary.

For the calibration, oil-free process water and oil is needed.
The calibration solutions are prepared in a vessel with a vol -
ume of approx.10 liters.

Homogenize the solution with a circulating pump or a motor -
ized stirrer before and during the calibration.

Connect the outlet of the vessel with the sample inlet of the
AMI Turbiwell.

Adjust the sample flow to approx. 20 liters per hour by a control
valve.

The signal must be stable while the sample is flowing. To check
the stability, navigate to menu 2.2.1 <Diagnostic>/<Sensors>/
<Turbidity> and observe the raw signal.
To start with calibration navigate to menu 3.1, <Maintenance>/
<Process Cal. ppm>. There you can choose between

Detect Zero:
The zero value determination is carried out with oil-free pro -
cess water.

Specify slope:
A sample with a known oil concentration is used to determine
the slope. The entered process value is used as the setpoint of
the calibration sample.
