The FreeStyle Libre 2 Plus sensor sends sensor glucose readings to your t:slim X2 insulin pump every minute. Control‑IQ technology uses these continuous glucose monitoring (CGM) values to predict glucose levels and automatically adjust insulin delivery every five minutes.
The numerical glucose value from the sensor will display on the t:slim X2 insulin pump and t:connect mobile app every minute. Meanwhile, the sensor data points in the CGM trend graph will update every five minutes.
Note: If your t:slim X2 insulin pump and t:connect mobile app lose connection, you will notice a gap in the CGM trend graph, as the sensor data will not backfill.
