Sensor calibration
After a new sensor is initialized, you can calibrate the
CGMS as needed. Please calibrate the system only
when blood glucose is relatively stable - the interstitial
glucose has a physiological lag compared to capillary
blood glucose so calibrate the CGMS when blood glu-
cose is rapidly changing may cause the CGMS to be
less accurate.
Please calibrate the system only using reliable blood
glucose test values - Use certied BG meter and test
strips that are within expiration date; ensure the BG
meter readings are consistent by performing two or
three repeating tests; make sure the nger is cleaned
with alcohol wipes and dried before the nger prick.
Avoid any calibrations in the rst 6 hours after the sen-
sor warming-up, which might affect the CGM accuracy
afterwards.
