   - Cut the FLS to the necessary length and install it into the tank.    - Cut the FLS to the necessary length and install it into the tank. 
   - Enable data transmission for the necessary input (for example, //Ain1//). It is recommended to set a frequent data transmission (like once in 10 seconds, for example). ​   - Enable data transmission for the necessary input (for example, //Ain1//).

-  - Draw a grid for your future calibration table. There will be two columns -- 'Liters' ​and 'Volts', and so many rows as parts you divide your tank into (+ O liters row). Write the beginning time of the operation.  +  - Draw a grid for your future calibration table. There will be two columns -- //Liters// and //Volts//, and so many rows as parts you divide your tank into (+ O liters row). Write the beginning time of the operation.  
-  - Divide the volume of your tank into 10-30 parts. Pour portions of fuel and each time write the current fuel level in the tank into your calibration table. Wait 2-3 minutes after each new portion. Continue till the tank is full. As a result, the first column of your table ('Liters') will be filled in.  +  - Divide the volume of your tank into 10-30 parts.

-  - Fill in the second column of the calibration table ('Volts'). Do not forget the zero point. The dynamics of changes in voltage can be analyzed through the table of messages itself or through parameter'​s chart (the button to switch between the table and chart view are situated above). If there are many messages, do not forget to load next pages.  +  - Fill in the second column of the calibration table (//Volts//). Do not forget the zero point. The dynamics of changes in voltage can be analyzed through the table of messages itself or through parameter'​s chart (the button to switch between the table and chart view are situated above). If there are many messages, do not forget to load next pages.  
-  - On the basis of gathered data, create a sensor in unit properties on the Sensors tab. Input the data from the calibration table to the Calculation Table Wizard. ​+  - On the basis of the gathered data, create a sensor in the unit properties on the //​[[cms/​units/​sensors/​sensors|Sensors]]// tab. Input the data from the calibration table to the //​[[cms/​units/​sensors/​calc#​calculation_table_wizard|Calculation Table Wizard]]//
   - Optionally, add two more points with values exceeding maximum and minimum. It makes the chart look better. For example, if your calibration table has the range from 1.2 to 4 volts, add a point 1 volt = 0 liters and the other point 5 volts = max liters. ​   - Optionally, add two more points with values exceeding maximum and minimum.

-  - When all data is in the Calculation Table Wizard, press the button ​'Generate Calculation Table'. Then go to the tab 'Calculation Chart' ​and press the button ​'Refresh' ​to estimate the result of your work. If necessary, return to the wizard, edit fields, and generate new table and chat.  +  - When all data is in the //​[[cms/​units/​sensors/​calc#​calculation_table_wizard|Calculation Table Wizard]]//, press the button ​//Generate Calculation Table//.

-  - Optionally, define minimum value (different from zero) on the Calculation Table tab (for example, 1 volt). This may help to avoid detection of false fuel filling when the accumulator is off.  +  - Optionally, define ​the minimum value (different from zero) on the //​[[cms/​units/​sensors/​calc|Calculation Table]]// tab (for example, 1 volt).
