Option Description
C. Ini Adjust the concentration of the solution before the addition if necessary.
C. End Adjust the concentration of the solution after the addition if necessary.
6. If the CAL PUMP NO or the Use Default Parameters option has been selected:
Option Description
ADD C Enter the concentration of the addition and press Enter . The pump
calibration starts.
INJ.TIME1 or
INJECT1 Enter the injection time (micro system pump) in seconds or the number
of pulses (pulse pump) for the first calibration solution and press
Enter .
INJ.TIME2 or
INJECT2 Enter the injection time (micro system pump) in seconds or the number
of pulses (pulse pump) for the second calibration solution and press
Enter .
IMMEDIATE Select YES or NO followed by Enter . If YES is selected an automatic
calibration will start immediately. No more input is required.
6.2.3 Calibration results
The following tolerances are defined for calibrations:
• Zone 1: The new calibration parameters are between 70% and 130% of the current
calibration parameters
• Zone 2: The new calibration parameters are between 50% and 70% or 130% and
150% of the current calibration parameters
• Zone 3: The new calibration parameters are between <50% and >150% of the current
calibration parameters
If the new calibration parameters are in Zone 1 , the calibration is considered successful
and the new parameters are used for all future measurements.
If the new calibration parameters are in
Zone 2 , it is necessary to CONFIRM the new
parameters. If YES is selected the new parameters are used for all future measurements.
If NO is selected the new parameters are rejected and the previous values are used for
all future measurements.
If the new calibration parameters are in
Zone 3 , the message ERROR CALIBRAT. is
displayed. Press Enter to continue then select RETRY to repeat the calibration or
ABORT to abort the calibration.
These messages only appear for a manual calibration, a process calibration, or if
IMMEDIATE YES was selected for an automatic calibration.
In a standard automatic calibration, or when IMMEDIATE NO was selected, the analyzer
will not ask for confirmation. If the calibration parameters are within Zone 1 the calibration
is considered successful and the new parameters are used for all future measurements. If
the calibration parameters are within
Zone 2 an error message SLOPE CALIB appears
on the display and the new calibration parameters are rejected. f the calibration
parameters are within
Zone 3 an error message ERROR CALIB appears on the display
and the new calibration parameters are rejected.
6.3 Analog outputs (ANALOG-OUT option)
The analyser has two analog outputs which are allocated according to the application:
• One connected to the concentration
• The other connected to the potential electrode line
For logarithmic and bilinear outputs, the minimum range is 1/100 of the maximum range.
The minimum range cannot be adjusted.
