Function Groups 

The main function and sub-function groups are organised in a matrix format for 

configuration and selection of parameters. The main function groups are: 

 

1)  Offset adjustment (OFS) 

2)  Temperature Measurement / compensation settings (Set 

o

C) 

3)  Control relay 1 configuration (SP1) 

4)  Control relay 2 configuration (SP2) 

5) Configuration 

(ConF) 

6) Calibration 

(CAL 

pH) 

 

4.3  Control Concept 

The main function and sub-function groups are organised in a matrix format as 

shown below.  These functions can be accessed via the front keypad for 

configuration and selection of parameters.
