Calibration
Since the sensor is very reliable a calibration is normally not neces-
sary.
A calibration is recommended if:
the cell constant is not known
the sensor is contaminated
the maintenance measurement shows a discrepancy.
Reagent for
the
Calibration:
Calibration solution 1.413 mS/cm (25 °C) 1000 ml. Prepare accord-
ing to DIN 38404 / ISO 7888: 1985 / EN 27888.
1
Stop the sample flow.
2
Navigate to menu <Maintenance> /<Calibration>.
3
Press [Enter] and follow the dialog on the Display.
4
Remove the sensor from the flow cell.
5
Clean the sensor carefully and rinse it with clean water, see
Maintenance of the Sensor, p. 41
6
Use a beaker and fill it with one liter calibration solution.
The beakers diameter must be so large that the sensor has a
distance of min. 3 cm from its edge.
7
Put the sensor into the beaker filled with calibration solution.
8
Wait at least 5 minutes to permit
temperature equilibration between
sensor and calibration solution.
9
Start the calibration procedure.
10
Press [Enter], to save the values if
the calibration was successful.
11
Install the sensor into the flow cell.
