Participants were trained to check capillary glucose versus sensor glucose values (calibration check) before evening meals; if sensor glucose was greater than capillary glucose by >3 mmol/l, the continuous glucose monitor was recalibrated and the calibration check was repeated before starting the closed-loop system.
On final assembly, each sensor underwent a calibration check in a nominal field of 100 V m−1.
These instructions reduced the risk of sensor error and the calibration check approach, expected to occur infrequently once every 3 4 weeks, was effective when assessed by computer modelling [ 15].
The module includes features to enable modification of the sensor data transmitting interval, adjusting sensor calibration and system time and includes hardware system check features.
We used a Vmax Series 2130 Autobox Spirometer (Sensor Medics Corp., Yorba Linda, CA, USA) and performed a calibration check every morning at 8 am.
If sensor glucose was above fingerstick glucose by >54 mg/dL, the continuous glucose monitor was recalibrated, and calibration check was repeated before starting closed loop.
T.H., M.A.M. and S.G.S. conceived the sensor calibration scheme.
However, only a few studies assess onsite signal processing circuitry and sensor calibration mechanisms for an accurate analysis8,9,10,11.
What the authors found was that a change in sensor calibration caused a shift that has been interpreted as ice acceleration.

During the sensor calibration, cells were incubated in the 37 °C non-CO2 incubator in 180 μl assay medium (XF Base Medium and 2 mM l-glutamine, pH 7.4).
