7.3 Calibrate at least once every 12 hours
Calibrate at least once every 12 hours, to ensure that the
blood glucose readings remain accurate. You can input the
blood glucose value in advance for calibration.
Warning
Calibrate at least once every 12 hours. Calibrating
less often than every 12 hours might cause sensor
glucose readings to be inaccurate, and you might miss a
low or high blood glucose value.
7.4 Other situations that require calibration
When the blood glucose value is significantly different
from the blood glucose reading, the reference calibration needs
to be re-entered.
8 Trend curves and reading lists
This chapter describes how to view the blood glucose
readings and trend curves. The trend curve provides additional
information that the meter does not have. The trend curve
shows the current blood glucose readings, the direction and
rate of changes in blood glucose, and also shows the state of
blood glucose over time.
Glucose meters and sensors measure blood glucose through
two different body fluids. Therefore, the values measured by the
meter may not match the sensor readings.
The greatest benefit of using continuous blood glucose
monitoring systems comes from dynamic information.
Concerned about the changing trend and speed of blood glucose
is more important than accurate blood glucose readings.
Warning
Continuous blood glucose testing cannot be used
as a basis for diabetes diagnosis, such as insulin injection.
It cannot replace the blood glucose meter. The value of
blood glucose may not be consistent with the reading of
blood glucose. Using glycemic readings as a diagnostic
basis for diabetes may result in low/high blood glucose.
The sensor reading range is 2.2-22.2mmol/L. When the
latest sensor readings are less than 2.2mmol/L, the latest sensor
readings, reading lists, and trend curves are displayed as
2.2mmol/L; when the latest sensor readings are greater than
22.2mmol/L, the latest sensor readings, reading lists, and trend
curves show 22.2mmol/L.
8.1 Trend curves
The trend curve of blood glucose readings is in the lower
part of the main interface, as shown in the following figure:
