      Warning: 20-24 (Strip calibration data is not up to date)

      Troubleshooting warning 20-24

      If your Sentia™ meter cannot retrieve new strip calibration data, try the following steps:

      1. Follow meter instructions as provided:
      2. Connect to WiFi to update.
      3. If already connected to Wi-Fi, reset this connection by turning the Wi-Fi off and then on again (make sure to select  when toggling between on/off options). 
      4. The Wi-Fi cycle triggers a connection to the UBI calibration website.
      5. Restart the test and re-enter the strip index number.
      6. If the error persists, contact your Supplier.

      Note: If the Sentia meter gets stuck on a 20-24 warning, try removing the device's end cap.  This can fix the issue by forcing the meter to push through a new error message (70-20).  Firmly re-install the end cap once the desired 70-20 error triggered.
