Cleaning/calibration

programs

You can choose from the following cleaning and calibration options:

Predefined program for:

• Cleaning the sensor

• Cleaning and calibrating the sensor

• Assembly retraction in measuring and service position

• User-definable programs without predefined program steps

You can freely configure all programs to suit your requirements. The predefined programs are used

for faster configuration.

Calibration and

measurement

Calibration options for pH glass, ISFET and ORP sensors:

• Single-point or two-point calibration

The buffer tables e.g. according to DIN, Endress+Hauser etc. are saved by setting the buffers used

and automatically calculating the pH values depending on the temperature.

• Automatic acceptance of calibration data for digital sensors with Memosens technology

Equipment architecture

Inputs and outputs

The CDC90 control unit consists of a Liquiline transmitter and a separate industrial PC (IPC).

The Liquiline transmitter acts as the peripheral interface for analog and digital signals. These are

controlled by an IPC that has a separate software program for the automation of the measuring

point.
