      How to Use the KetoScan Lite

      1. Attach a mouthpiece or a drinking straw into the sampling hole. Press and hold the power button for 2 seconds to turn the unit on.
      2. The total number of tests available before calibration is required and the previous test result will be displayed.
      3. Once "bLo" is displayed on the screen, users can start to blow with a slow and steady breath until the unit vibrates.
      4. "SdC" will be displayed once the self-diagnostic testing is completed. A countdown will commence before the main test can be conducted.
      5. The test result will be displayed for 15 seconds before the unit powers off.
      6. Press and hold the power button for 2 seconds to turn the unit off.

      Self-diagnostic test

      The self-diagnosis function is a patented, exclusive KetoScan technology used to get rid of any miscellaneous gases or particles surrounding the sensor using the exhaled breath of the user.

      This WILL NOT count as a test as it is a preparation before the main measurement.
