5.3.3 CONFIGURATION
!
Note!
Some settings that can be made in this menu affect the defaults in the PARAMETER ENTRY menu.
In view of this, complete the CONFIGURATION menu first during initial start-up.
Option Range of adjustment
(default 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:
NO-A
NO-B
NO-C
This setting displays the parameter that is being measured
(e.g. NO-A). This is defined by the product specification
and set in this option 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 settings are reset to default.
You have to set date and time to the current before (scroll
to the third last fuction in this menu).
With the reset, the date for the 1st calibration and for the
1st flushing are set to the next day.
Measuring unit
mg/l -NO

-N
If you want to determine the ion concentration, you have
to use the appropriate calculation factor. These factors are
not available by the software.
Calibration factor
0.20 ... 5.00
1.00
The calibration factor is the ratio of the measured
concentration of the calibration standard to the
pre-defined concentration of the standard (see
"PARAMETER ENTRY", calibration solution). The
deviation results from factors such as reagent ageing,
ageing of constructive components, etc.
The calibration factor compensates for these effects. CA
71 checks the registered calibration factor logically. If the
factor lies outside of the error tolerance, the calibration is
automatically repeated. If the repeat also lies outside, an
error message appears and the analyser continues to work
with the most recently registered, logically correct factor.
The last 10 calibration factors are filed in the memory
with the date and time and can be retrieved by pressing
the
J
key.
The calibration factor ca be changed manually.
Concentration
offset
0.00 ... 50.0 mg/l
The offset specifies the zero shift of the calibration
function. (Change the sign with the
J
key.)
Dilution 0.10 ... 1.00
If the sample is to be diluted between taking the sample
and the analyser, the dilution factor has to be entered
here (factor times measured value).
Delay to sample
20 ... 300 s
80 s
Dosing time for sample or standard (20 ... 120 s). 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 there is sufficient
sample available, select the highest possible value.
Analog output 1
0 ... 20 mA / 4 ... 20 mA
Selection for the scope of channel 1 measuring range. If
the concentration measuring range is 0 ... x mg/l, this
corresponds to 0 mg/l either 4 mA or 0 mA. The end of
the measuring range is the same in both cases at 20 mA.
Analog output 2
Two-channel version only! Selecting scope of channel
2 measuring range.
The scopes of the measuring range are independent of
each other for channel 1 and channel 2 and are
determined by the start of measuring range (channel 1 /
channel 2) or end of measuring range (channel 1 /
channel 2) setting in the PARAMETER ENTRY menu.
