Calibrating your sensor

Device: MiniMed™ 630G insulin pump (MMT-1715K)

Calibration
To calibrate, you must use a blood glucose reading from your blood glucose meter and enter that value into your pump. The pump will accept BG meter readings between 40 mg/dL and 400 mg/dL. Your continuous glucose monitoring system requires BG meter readings in order to provide you with sensor glucose readings. CGM does not eliminate the need for BG meter testing and calibrations are important for getting the best performance from your CGM system.

Approximately two hours after starting a new sensor or any other a calibration is necessary, you will receive a Calibrate now alert.

If you cannot calibrate right way, for example, if you will be driving or in a meeting, you can set the Snooze to remind you to calibrate in the time that you set. You can change the time if you desire, and press Select.

Calibrating the Sensor
There are several different ways that you can enter a BG reading to calibrate the sensor.

Option 1:
Using the CONTOUR®NEXT LINK 2.4 Meter, select Calibrate Sensor after the BG is sent from the meter to the pump.

Option 2:
Using the Bolus Wizard calculator, select Yes to calibrate sensor after a bolus is delivered.

Option 3:
Using the Home Screen graph, highlight the sensor graph, press and hold select. Enter BG and select Calibrate.

Once you have entered a calibration BG, the Home screen will show you that the system is calibrating. You will start seeing sensor glucose readings again in about 10-15 minutes.

NOTE: If you notice a large difference between your BG meter reading and sensor glucose readings, wash your hands and do another BG fingerstick test to help ensure a more accurate reading. Also check the sensor site and make sure the sensor overtape is holding the sensor in place. If it is not, you will need to remove the sensor and insert a new one.

Calibration Reminder
You can use the Calibration Reminder to give you notice before the next calibration is necessary. For example, if you calibrated at 7:00A your next calibration would be due at 7:00P (12 hours later). If your reminder is set for 4 hours, you would receive a Calibration Reminder at 3:00P which is 4 hours before the calibration is due. This can help ensure you calibrate 3-4 times a day. The Calibration Reminder defaults On with a reminder time of 1:00 hour.

1. Select Menu.

2. Scroll to Reminders and select.

3. Select Calibration.

4. Select Reminder to turn the reminder on or off.

5. If you turn on the reminder, select Time and enter a time between 5 minutes and 6 hours.

6. Select Save.
