Liquistation CSF39 Maintenance
Hauser 167
Replacing the sensor while ensuring measuring point availability
If an error occurs or the maintenance schedule stipulates that the sensor has to be
replaced, use a new sensor, or a sensor that has been precalibrated in the laboratory.
• A sensor is calibrated in the laboratory under optimum external conditions, thereby
ensuring better quality of measurement.
• You must perform onsite calibration if you use a sensor that is not precalibrated.
1. Remove the sensor that requires maintenance.
2. Install the new sensor.
 The sensor data are automatically accepted by the transmitter. A release code is
not required.
Measurement is resumed.
3. Take the used sensor back to the laboratory.
 In the laboratory you can get the sensor ready for reuse while ensuring the
availability of the measuring point.
Prepare the sensor for reuse
1. Clean sensor.
 For this purpose, use the cleaning agent specified in the sensor manual.
2. Inspect the sensor for cracks or other damage.
3. If no damage is found, regenerate the sensor. Where necessary, store the sensor in a
regeneration solution (→ sensor manual).
4. Recalibrate the sensor for reuse.
