4 Press ACT. The SET RISE RATE LIMIT screen flashes the rate alert default setting: OFF.
5 Select the Rise Rate Limit. The range and increments are the same as the Fall Rate Limit (see step 3
above).

AUC calculation
The AUC (Area Under the Curve) feature measures how much and how long your sensor glucose
measurements are outside the user-defined AUC Limits. Check with your healthcare professional to
determine the AUC settings that are best for you. The AUC Limits are different than the Glucose Limits.
The AUC Limits are used to analyze the sensor glucose measurement data that is stored in your system.
The closer the AUC values are to zero, the closer your SG values are to your AUC Limits. If your AUC values
are zero, then your SG values are within your AUC Limits.
In the following example the AUC Limits are defined as 70 to 140 mg/dL (3.9 to 7.8 mmol/L), and are
represented by the light shaded area. The actual AUC is the dark shaded area, between the sensor glucose
curves and the defined limits. On average, the SG exceeded the AUC high limit by 30 mg/dL (1.7 mmol/L),
and the AUC low limit by 3.9 mg/dL (0.2 mmol/L).
