The next step in the calibration process is to fill the tank and indicate the volume of fluid in the tank at various points while filling the tank. This process should be started with an empty tank. You only need to indicate two calibration points for a rectangular tank, and can use up to 16 calibration points for a tank with a more complex shape. Figure 206 shows a screenshot of the first calibration step. Enter the first calibration point with an empty tank (0.0 Gallons/liters) by pressing the Accept key. The “Current Point” highlight will advance to the next point.

Each time you press Accept during this process and after the Current Point highlight advances, put more fluid into the tank, and note the total volume of fluid pumped into the tank at this point. Use the Increase and Decrease keys to set the current tank level to the appropriate value, and then press the Accept key to store the current calibration point and advance to the next calibration point. Figure 207 shows a screenshot of these intermediate calibration points.
