2 Notes on software description

2.1 Types of setting

• Display fields

– You can only read the values, not change them.

• Selection fields

– You receive a list with options.

– You select one of these options.

• Input fields

– There are value ranges with upper and lower range limits that depend on the measured

variable configured and its units.

– There are also menu functions where you can enter arbitrary text. The number of

characters is then limited.

– Set a value with the navigator:

Turn to increase/reduce a value/letter/special character

Press to confirm or to enter the next character for arbitrary text.

2.2 Editing tables

You can set some software functions using a table:

• The number of columns depends on the menu function that is set via the table.

• You can add lines ("Insert") or delete lines ("Del").

• The maximum number of lines also depends on the menu function in question.

• You can press "Esc" at any time to exit the table and stop entering information.

• If the values entered result in a valid table, you receive the message "Table is valid" and the

options:

–Save table

– Continue edit table

– Discard table

• If the values entered are invalid, an error message is output with the options:

– Continue edit table

– Discard table

Compensation pH Switch=off

The concentration value is calculated as HClO.

Switch=on

The pH value is used to calculate a cumulative

concentration value of HClO and ClO- (total DI).

You can choose either to use the measured value from the

Using the 4 mA and 20 mA value, you map the measuring

range in the corresponding engineering unit of the

measured variable. The smaller the span you select between

the 4 mA and 20 mA value, the more accurately you map

this measuring range.

!Note!

The following minimum spans are settings that the software

allows but might not necessarily be useful for your process.

For this reason, use values that are plausible for your

process, within the limits of which you can generally expect

your measured values.
