Readings can be more meaningful when they are grouped into categories. For example, your doctor may be particularly interested in readings taken two hours after a meal. Using the category selection box, you can quickly select which types of readings are to be displayed and included in the statistics, graphs and reports.
Only categories that have been used when entering a reading on the PDA will appear in this box. Available categories are :
Unclassified
After Meal
Fasting
Breakfast
Lunch
Dinner
Bedtime
