Page 15: Calibration
Calibration of the fuel tank is necessary to verify the conformity of the digital code issued by the Omnicomm LLS 5 sensor to the fuel volume in a particular fuel tank. Calibration of the fuel tank is performed by refueling up the tank – from empty to full, with a certain refueling interval, and recording the Omnicomm LLS 5 sensor readings in the cali-bration table. - Page 16 Calibration If the sensor reading column is not displayed, press the “Add sensor” button. Select the type of sensor. Specify the network address set for the sensor during the setup.
- Page 17 20 10. Press the “Finish calibration” button 11. Save the calibration table in a calibration file (.ctb), Omnicomm Online (.xml) file, in the Terminal or in the Indicator, by pressing the “Export” button When performing the calibration table export to the Omnicomm Online (.xml) file, the “Export”...
