In the DIA:CONN app, advanced features include Bolus calculator, Basal time setting (Missing Basal notification), Injection time setting, Preset carbs, Preset Injection, Predicted BG Graph, and COB calculation.
Bolus calculator
To use the bolus calculator, the type of insulin must be either Rapid-acting or Ultra-rapid-acting, and bolus-related settings must be configured in advance. The prerequisite settings include ICR, CF, Insulin Type / Duration, and Correction range.
Bolus Calculator Setting
The bolus calculator settings include Bolus Calculator Mode, CF, Insulin Type / Duration, Correction range, ICR, and Preset carbs.
Bolus Calculator Mode
Choose how you want to use the bolus calculator. There are four calculator modes: Fixed Meal, which presets the amount of insulin for each meal; Estimated Meal, which presets the amount of insulin for three different meals; Carb Counting, which is calculated by entering the amount of carbohydrates consumed; and Advanced Carb Counting, which is calculated by entering the amount of carbohydrates consumed and the time of absorption.
1Select the calculator mode menu.
2Choose the desired calculator mode.
3Press the save button to complete the settings.
Correction Factor(CF), Insulin Sensitivity Factor(ISF)
The glucose level (mg/dL) that can be controlled by one unit of insulin.
1Enter the Correction Factor menu.
2Press the Add button.
3Set start time, end time, and correction glucose per 1U.
4Press confirm to verify if it has been added to the correction factor list.
5Press Save button to save.
Insulin/Duration of Action
It is the menu for setting insulin duration, peak time, and trend application time. Insulin duration refers to the time insulin acts in the body, peak time is the time when insulin has the maximum effect in the body, and trend application time is the value used by the DIA:CONN Bolus Calculator when calculating glucose 10 minutes, 20 minutes, and 30 minutes after the set trend application time.
Enter the Insulin Duration menu.
Set insulin duration, peak time, and trend application time.
Press confirm to save.
Correction Range

1Enter the Correction Range menu.
2Press Add button.
3Set start time, end time, upper limit, lower limit, and target value.
4Press confirm to verify if it has been added to the carbohydrate ratio list.
5Press Save button to save.
ICR (Insulin to Carbohydrate Ratio, Carbohydrate Factor)
It refers to the amount of carbohydrates (g) that one unit of insulin can adjust.
1Enter the Carbohydrate Ratio menu.
2Press Add button.
3Set start time, end time, and amount of carbohydrates per 1U.
4Press confirm to verify if it has been added to the carbohydrate ratio list.Press Save button to save.
Frequently used carbohydrates
The feature of setting and saving frequently used carbohydrates allows you to quickly load and use them during bolus calculator injections for added convenience.
1Go to the frequently used carbohydrates menu.
2Press Add button.
3Set the name, description, and carbohydrate amount.
4Press Save button to save.
5Check in the list to confirm that the values you saved have been entered correctly. Users can add or delete frequently used carbohydrates at any time.
6Press the bolus calculator button in the pen tab.
7Press the icon for frequently used carbohydrates next to the carbohydrate intake.
8Select one from the list that the user has added.
9You can confirm that the value selected by the user is loaded.
Meal fixed amount
When the calculator mode is set to meal fixed amount method, set the fixed insulin injection amounts for each mealtime and per meal.
1Go to the meal fixed menu.
2Set the fixed insulin injection amounts for each meal time (breakfast, lunch, dinner, snack).
3Press Save button to complete the configuration.
Meal estimation amount
When the calculator mode is set to meal estimation method, set the fixed insulin injection amounts for each mealtime and each carbohydrate quantity.
1Go to the meal estimation menu.
2Set the fixed insulin injection amounts for each carbohydrate quantity (small, medium, large) corresponding to mealtime, including breakfast, lunch, dinner, and snacks.
3Press Save button to complete the configuration.
Injecting with the Bolus Calculator
WARNING
If you are using glucose information provided by an external connected device, always verify whether the glucose measured by that device matches the one received by the system before injection. If there is a difference in glucose, it may result in the glucose being managed in a direction different from the prediction.
You need to set the insulin as either long-acting or rapid-acting.
2After configuring the current glucose, meal insulin amount, carbohydrate intake, CGM trend reflection, food type, etc., press the 'Calculate' button.
The configured values show the settings from section 8.1.1, Bolus Calculator Settings.
The current glucose is automatically applied if there is a CGM value within the last 5 minutes, and you can manually change the value if needed.
You can apply the carbohydrate intake value through food exchange units or frequently used carbohydrates, and you can manually change the value if needed.
The CGM trend reflects the value calculated from CGM if there is a CGM value within the last 5 minutes. Users can manually change the value.
3Depending on the calculation result, either bolus injection or carbohydrate intake will be suggested.
The calculation formula can be verified through the calculation result at the bottom of the button, and detailed items can be expanded for further inspection by clicking on 'View Details'.
If the bolus calculator mode is set to [Enhanced Carbohydrate Calculation Method], the insulin injection screen will additionally display the predicted glucose graph.
4If the 'Inject Insulin' button is displayed, press the button and refer to the 7.4 for injection. If the 'Carbohydrate Intake Record' appears, press 'Save Carbohydrate Intake' to save. The carbohydrate intake amount is user-adjustable, and the reason for the change should be entered at that time.
Preset Injection
Preset injection is a convenient feature that allows you to quickly load frequently used insulin injection settings by setting them with a name and injection amount.
1Move to the preset injection in the bolus and meal settings.
2Press the Add button to move to the preset injection addition screen.
3Enter the name, description, and injection amount.
4Press Save button to save.
5Check in the list to confirm that the values you saved have been entered correctly. Users can add or delete presets at any time.
1In the pen tab, press the quick injection button.
2Press the preset in the top right corner of the insulin injection screen.
3Select one from the list that the user has added.
4You can confirm that the value selected by the user is loaded.
Injection Time Setting
The injection time setting is a convenient feature that notifies you when there is no injection history at the registered time.
1Go to the injection time setting menu.
2Press the 'Receive Non-injection Notifications' button to turn it ON.
3Press the Add button to move to the injection time setting screen.
4After setting the start time and end time, press the Confirm button.
5Check the list to confirm the injection time you have set.
6Press Save button to save.
If there is no injection history at the set injection time, it will be displayed in the pen section as shown above.
Basal Time Setting
The basal injection setting is a convenient feature that notifies you if there is no basal injection at the registered time.
1Go to the basal time setting tab.
2Press the 'Receive Non-injection Notifications' button to turn it ON.

4Enter the start time, end time, and injection amount.
5Press 'Confirm'.
6Check the list to see if the set basal time is present, and then save.
If there is no injection history at the set basal time, it will be displayed in the pen section as shown above.
Real-time Prediction Graph
The top active carbohydrate section and the three prediction graphs (glucose prediction, active insulin prediction, active carbohydrate prediction) are only available in the bolus calculator mode when [Enhanced Carbohydrate Calculation Method] is selected.
Glucose Prediction
The glucose prediction graph shows the prediction of glucose levels using information such as active insulin, active carbohydrates, and CGM glucose trends.
Press the top recent glucose section to navigate.
Active insulin prediction
The active insulin prediction graph predicts and displays the absorption model for the injected insulin.
Press the top insulin section to navigate.
Active Carbohydrates Prediction
The Predicted Active Carbohydrates Graph predicts and displays the absorption model based on the consumed amount of carbohydrates.
Press the Active Carbohydrates section at the top to navigate.
