Setting the Rate of Change Alerts
The Rate of Change alerts tell you when your sensor glucose (SG) changes at, or faster than, the per-minute
rate pre-selected by you. There are two alerts:
• FALL RATE for SG decreases at or faster than your pre-selected rate. The pump plays two consecutive
tones, in falling pitch, if an audible beep has been selected as the alert type.
• RISE RATE for SG increases at or faster than your pre-selected rate. The pump plays two consecutive
tones, in rising pitch, if an audible beep has been selected as the alert type.
You can set one or both Rate of Change alerts. The rate of change alert default setting is OFF. When you press
or , 0.220 mmol/L (4.0 mg/dL) displays. This value changes up or down with each additional press.
The explanation in the following table shows how the Rate alerts work.
If you set the number
Then
Lower than 0.220 mmol/L/min
(4.0 mg/dL/min)
• The system is more sensitive to SG changes
• Alerts are more frequent than if you use a higher number
Higher than 0.220 mmol/L/min
(4.0 mg/dL/min)
• The system is less sensitive to SG changes
• Alerts are less frequent than if you use a lower number
To set up the Rate of Change alerts:
1 Make sure the EDIT SETTINGS screen is open.
Main > Sensor > Edit Settings
2 Select Rate Alerts, then press ACT. The SET FALL RATE LIMIT screen flashes the rate alert default setting:
OFF.
3 Select the Fall Rate Limit.
• Range: mmol/L/min
mg/dL/min
from 0.065 to 0.275
from 1.1 to 5.0
• Increments: mmol/L/min
mg/dL/min
0.005
0.1
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
