Windows (driver)

• Install Zadig: https://zadig.akeo.ie/ and install the WinUSB driver for your Accu-Chek device.
• Run Zadig as Administrator if required.
• Run the built executable: .\target\release\accuchek.exe

PDF Export

Exported reports contain statistics and charts in the chosen unit (mg/dL or mmol/L).
