SMART BILGE Calibration Check Procedure

The purpose of this procedure is to verify the accuracy of the SMART BILGE

Equipment 

Procedure 

1. Ensure that the separator is stopped and that no water is flowing through the monitor.
2. Use the down key on the front panel to access the user menu.
3. Select diagnostics – view detectors. This will force monitor into clean water flushing 
   Mode and clean the cell. Operate the manual clean to ensure the cell tube is clean.
   
4. Press the left hand key (Enter). This will stop clean water flowing through the cell. - Note: If you have a flowmeter fitted on your OCM this will go into alarm stating no flow. You can ignore this error message and continue.  
   
5. Remove the manual clean attachment from the outlet block.
6. Use the down key to access the calib menu.            
7. Use the syringe to remove all fluid from the cell  and dispose of.    
   
8. Take the bottle of 10ppm Calibration Check Fluid, shake for one minute to obtain uniformity, and then leave to stand for a further five minutes, to release any entrained air bubbles.
9. Pour in a quantity of the 10ppm Calibration Check Fluid into the outlet block,  to the level of the pipe connection. Drain by using the syringe and dispose of.
   Pour in a further quantity of the Calibration Check Fluid, cover the outlet block to exclude light and wait for one minute. Check that the display reads 10 ppm  ± 3.            
                                                      
10. Pour clean potable water into the cell and then use the syringe to remove it.
11. Take the bottle of 20ppm Calibration Check Fluid, shake for one minute to obtain uniformity, and then leave to stand for a further five minutes, to release any entrained air bubbles.
12. Pour in a quantity of 20ppm Calibration Check Fluid into the outlet block, to the level of the pipe connection. Drain by using the syringe and dispose of. 
    Pour in a further quantity of the 20-ppm Calibration Check Fluid, cover the outlet block to exclude the light and wait for one minute. Check that the display reads 20ppm ±3.
13. Drain the fluid by using the syringe and dispose of. Replace the manual clean attachment.
14. Turn off power.

Provided that tests according to 3.9 and 3.12 produce 10ppm ±3 and 20ppm ±3 respectively, the monitors factory calibration is verified, and a Calibration Check Certificate can be issued by an authorised service centre against the device provided the factory calibration certificate is valid. 

*Note:

1. Sufficient materials have been supplied to give a minimum of two operations, however it should be noted that the Calibration Check fluids have a limited shelf - life.

2. Calibration Check Fluids must be stored in a cool dark place for the duration of their  shelf life.

3. Calibration Check Fluids must be disposed of in accordance with local disposal    instructions for chemical waste.
