• 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.
7.3 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.
1. Select ANALOG-OUT with the scrolling keys and press Enter. Select the type of analog output:
Option
LINEAR
LOGARITHMIC
DUAL RANGE
2. If linear output is selected:
Option
START XX.XXEXX Define the concentration corresponding to the 0 or 4 mA current for the start of output
END XX.XXEXX
START XXX.XmV
END XXX.XmV
The choice between 0 and 4mA is available in the PMXXXX, Adjust Iout menu option.
