1
• Switch on radiation
• Fill the pipe with a medium of known density or take a sample of the medium
during the calibration and determine its density in the laboratory, see Step 4).

Enter the number of the calibration point:
• For one-point calibration: "1"
• For multiple point calibration: "1" - "9"
• For recalibration: "10"

• For one-point calibration: select "No";
this completes the calibration
• For multiple point calibration: select "Yes";
repeat steps 1 - 10 with a medium of a different density
• For recalibration: select "No";
this completes the recalibration
