5.2.3 CONFIGURATION
!
Note!
Some settings that can be made in this menu affect the values in the PARAMETER ENTRY menu.
In view of this, run through the CONFIGURATION menu first during
initial commissioning.
Menu item Range of adjustment
(factory settings in bold) Display Info
Code number 03
Input 03.
If an incorrect code is entered the program exits the
sub-menu.
Photometer
Depending on specification
HY-A
The setting displays the parameter that is being measured.
This is defined by the product specification and set in this
menu item at the factory. Do not change the value.
Otherwise, you will receive an "Incorrect photometer"
error message.
Default settings Yes / no
If "yes" is selected, all the settings are reset to the factory
settings.
You must set the current date and time (scroll through
the menu, third-last point).
In the event of a reset, the date for the 1st calibration and
the 1st flush is set to the following day.
Measuring unit
μ
g/l
The measuring unit selected depends on the type of
photometer. This setting also affects the scope of the
measuring range.
Calibration factor 0.10 to 10.00
The calibration factor is the ratio of the measured
concentration of the calibration standard to the
predefined concentration of the standard (see
"PARAMETER ENTRY", calibration solution). The
deviation results from factors such as reagent aging, aging
of constructive components, etc.
The calibration factor compensates for these effects. CA
71 checks the registered calibration factor logically. If the
factor is outside of the error tolerance, the calibration is
automatically repeated. If the value is still outside the
tolerance range after repeating calibration, an error
message appears and the analyzer continues to work with
the most recently registered, logically correct factor.
The last 100 calibration factors are stored in the memory
with the date and time and can be retrieved by pressing
the
J
key.
The calibration factor can be changed manually.
Optional dilution modules are taken into consideration in
the calibration factor.
Concentration offset 0.00 to 50.0 mg/l
The offset gives users the option of adapting to an
external comparison measurement.
(Change the sign with the
J
key.)
Dilution
0.10 to 10.00
1.00
If the sample is diluted externally between taking the
sample and the analyzer, the dilution factor has to be
entered here.
If an optional dilution module is used, the factor remains
1. The dilution is taken into consideration by means of
the calibration factor.
Delay to sample
20 to 300 s
80 s
Dosing time for sample or standard. During this time, the
entire system is flushed with sample or standard, so when
the reagent is added there is definitely only fresh sample
in the mixer. If sufficient sample is available, or in the
event of an external collecting vessel with a long supply
line, select the highest possible value.
