To display your current glucose reading and activate Control-IQ technology on your t:slim X2 insulin pump, you will need to connect your pump with a compatible continuous glucose monitoring (CGM) sensor.*
Tandem Diabetes Care and Dexcom have created life-changing diabetes management solutions with more than a decade of collaboration. Here is a breakdown of what Dexcom CGM sensors are currently compatible with your t:slim X2 insulin pump.
The t:slim X2 insulin pump (software version 7.3 or later) is compatible with all versions of the Dexcom G6 sensor.
Check all your sensor boxes. If the side of the box has a white line below the LBL number (see image example) then the Dexcom G7 sensor is compatible with your pump.
