Section 2 General information 2.1 Safety information Please read this entire manual before unpacking, setting up or operating this equipment. Pay attention to all danger and caution statements. Failure to do so could result in serious injury to the operator or damage to the equipment. Make sure that the protection provided by this equipment is not impaired, do not use or install this equipment in any manner other than that specified in this manual.
Remove the measurement sensor from operation before carrying out any maintenance or installation work. The FP 360 sc sensor is a UV fluorimeter used to continuously measure the concentration of PAH (polycyclic aromatic hydrocarbons) in water. The measurement values can be converted to reflect the total oil content for mineral oils using lab data.

General information 3. Cover the sensor measurement window with a sheet of white paper (do not use recycled paper). 4. Vary the distance between the measurement window and the paper. The measurement value on the display will change accordingly. Note: In air, the measurement value displayed is not exactly zero due to reflections on the window surface (refer to section 4.5.3 on page...
Section 3 Installation D A N G E R Personal injury hazard. Only qualified personnel should conduct the tasks described in this section of the manual. N O T I C E If the sensor is not fully inserted, sun protection is recommended in high ambient temperatures and intense solar radiation to protect against thermal and UV effects.

Operation 4.5 Calibration 4.5.1 Factory calibration The calibration curve zero point and slope are preset. Retrospective calibration of these basic settings is generally not required outside of the inspection intervals. Do regular zero point checks to make sure that impurities or faults are being detected (refer to section 4.5.3 on page 21).
Operation 6. Enter the factor as the slope (refer to section 4.5.4.1 on page 21). Example for engine oil Example for naphthalene Lab value: 4.0 ppm oil Lab value: 420 ppb PAH Measurement value shown : 2.4 ppm oil Measurement value shown : 120 ppb PAH...
Operation 4.5.4.2 Adjust the zero point (OFFSET) 1. Open the MAIN MENU. 2. Select SENSOR SETUP and confirm. 3. Select the corresponding sensor and confirm. 4. Select CALIBRATE and confirm. 5. Select CONFIGURE and confirm. 6. Press OFFSET and confirm. 7.
Section 5 Maintenance The inside of the sensor is maintenance-free. The cleanliness of the measurement window in the sensor head has an impact on the accuracy of measurements. Check the measurement window at regular intervals to make sure it is clean. The required frequency of these checks is dependent on the measuring medium.
Maintenance 5.3 Cleaning the measurement windows C A U T I O N Cleaning agents can be hazardous to health. Wear protective equipment and avoid direct contact with cleaning fluids. N O T I C E Other cleaning agents can damage the material. Damage caused by cleaning carried out incorrectly is not covered by the warranty.
