The general range limits that you set during initial setup will apply to all untagged glucose results unless mealtime flagging is turned on. The blood glucose meter also has a meal tagging feature to help you get blood glucose readings before and after a meal. If you enable mealtime marking, you can set additional lower and upper range limits for meals.
On the Settings screen, highlight Range to edit the general range limits, then press OK. Push ∧ and ∨ to set the upper and lower limit, respectively, and then press OK The message “Saved” appears to confirm that the displayed lower and upper range limit values are now saved in the blood glucose meter. To change the Meal Range Limits, first check the Settings screen to make sure Meal Tagging is turned on. Then, on the Settings screen, highlight Range, then press OK. Highlight Before Meal or After Meal and press ∧ and ∨ to set the range limits for before and after to change the meal. At the end of the process, the message “Saved” appears to confirm that the range limits displayed for before and after the meal are now saved in the meter.
Be sure to talk to your doctor about which lower and upper range limit values are right for you personally.
