Measuring Amount Of Petrol Residue In Diesel

Information 

Risk of damage to sensor head on fuel detector.

• Protect sensor head to prevent the ingress of fluids. 
• Only perform test when filter pad is affixed. 
• Do not blow out sensor head using compressed air. 

Information 

Start the test immediately after filling the measuring cylinder with fuel.

• Outgassing petrol will give an incorrect test result. 

1. Connect fuel detector to a 12 V power source.
   1. 1.1 Variant 1: Connect directly into 12 V socket or cigarette lighter in the passenger compartment.
   2. 1.2 Variant 2: Connect to the vehicle battery using adapter for battery connection.
2. Affix filter pads -1-  for fuel detector to the sensor head -2-  on the fuel detector.

   Fuel detector

   1. 6.1 Press -1-  Test button. The self-test takes 1 minute.
   2. 6.2 LED -2-  lights up green - Fuel detector is ready for the test.
   3. 6.3 LED -3-  lights up red - Check power supply/sensor head and repeat test.
7. Push -1-  fuel detector -2-  into the measuring cylinder -Arrow-  .

   1. 7.1 Coat O-ring -3-  with fuel.
   2. 7.2 Press button -4-  for bleeder valve in the fuel detector.
8. Start test for measuring the amount of petrol residue in the diesel.

   Test

   1. 8.1 Press -1-  Test button. The test takes 3 minutes.
9. Evaluation of test result.

   Evaluating test result

   1. 9.1 LED -1-  lights up green = no petrol residue in the diesel.
   2. 9.2 LED -2-  lights up red = petrol residue in the diesel.

Information 

• Only carry out the analysis in well-ventilated rooms and at room temperature (20° Celsius). 
• Before starting the analysis, have a good look at the information on the CD and read the leaflet (supplied in the case) carefully. 
• This analysis can only determine a reference value; a laboratory test is required for an exact analysis. 
• The analysis does not constitute a legal basis; it is the starting point for further steps.

5. Assign the scale value using the table below.

   Scale value (at 20° Celsius)	Assessment	Note
   below 0	Case for fuel laboratory (neither petrol nor diesel)	Laboratory test required
   0... 5.5	Petrol EN 228
   4.5... 6.5	E 85
   approx. 7	E 100 (pure ethanol)
   7... 9	No evaluation possible (neither petrol nor diesel)	Laboratory test required
   9... 11	Diesel in Asia (Russia/India)
   10... 13	Diesel in accordance with EN 590 (Europe)
   13... 15	No evaluation possible, "wild mix"	Laboratory test required
   15... 17	Biodiesel	Laboratory test required
   above 17	Measuring spindle does not stay in the fuel (water-like density)	Laboratory test required

   Information 

   • Fuel, fuel mixes and cleaning mixes must be disposed of according to the applicable national regulations. 
6. After testing the fuel, wash out and wash off measuring equipment thoroughly using the cleaning brush, washing-up liquid and hot water.
