When performing calibration and subsequent tank calibration using a single type of fuel, it is recommended to enable Auto Adjustment (see Sensor](https://doc.omnicomm.ru/ru/omnicomm_lls_6-manual/setting/set|Sensor) Configuration). Enable Auto Adjustment and save the settings to the fuel level sensor.

1. Pour fuel into the measuring container.
2. Immerse the Omnicomm LLS sensor into the fuel along the entire length of its measuring section.
3. Wait for the green “Stabilized” indicator to appear.
   Press the “Full” button — the value corresponding to a full tank will be recorded.
4. Remove the Omnicomm LLS sensor from the container and allow the fuel to drain from the measuring section for 1 minute. Press the “Empty” button — the value corresponding to an empty tank will be recorded.
5. Press the “Write to Device” button.
