At times, the Dexcom sensor and the CGM in the Cloud will display a code less than the number 10. THESE ARE NOT GLUCOSE LEVELS! These are error codes that can be interpreted using the table below. For mmol values, divide the number in the Pebble column by 8.
CAUTION: Dexcom reports glucose values that are under 40 mg/dl (under 5 mmol) as LOW. If glucose levels are that low no number appears, just the word LOW.
