8 Configuration
8.2 Input of Offsets
Corrections can be done as follows:
•
input of offsets for the values calculated by the transmitter (e.g. concentration in mass percent)
•
input of offsets for the measured primary physical quantities (e.g. refractive index, temperature)
8.2.1 Input of Offsets for the Values Calculated by the Transmitter
It is possible to correct the values calculated by the transmitter, i.e. by addition of a constant value to the selected
physical quantity or the normalized refractive index. The corrections can be defined in the following displays:
.
The physical quantities and scales available for the selected fluid are
displayed. Possible physical quantities are e.g. volume concentration
or mass concentration. A typical scale is for example the Brix value for
the concentration of a sugar solution.
Select the physical quantity. Press ENTER.
If several units of measurement are available for the selected physical
quantity, they are now displayed.
The display will not be indicated if a scale is selected.
Select the unit of measurement to be used. Press ENTER.
If no offset is to be defined for the selected physical quantity or for the
normalized refractive index, select
NO
. Otherwise select
YES
. Press
ENTER.
The selected physical quantity is displayed in the upper line. Select
YES
to define an offset for this quantity. Press ENTER.
Enter the offset. The previously selected unit of measurement is dis-
played. The maximum possible offset is 10 % of the valid value range
of the selected physical quantity.
Example:
The glucose concentration is measured with the Brix scale selected as unit of measurement. The
Brix scale ranges from 0...100 °. The maximum offset is 10 °. Press ENTER.
If no offset for the normalized refractive index is to be defined, select
NO
. Otherwise select
YES
. Press ENTER.
Enter the offset for the normalized refractive index. The offset has to
be within the range ± 0.100000. Press ENTER.
