Rules in DiaBox

(English Version)

(please make sure the user read the following disclaimer before entering the calibration mode implemented in Android v20201115 & iOS v7.4.5 and higher)

Disclaimer: This calibration feature is highly experimental. It is provided as an information resource only and is not to be used or relied on for any diagnostic or treatment purposes. You do it at your own risk and you are fully responsible for any damages, loss, injury, or liability whatsoever suffered as a result of your reliance on this feature.

Calibration implemented in DiaBox follows the simple rules listed below:

  • Rule 1—Sensor Status Check

Calibration can be enabled only when the sensor is in “Ready” status. It means that calibration doesn’t work when your sensor is in “warm-up“, “sensor error“, or “sensor end” status.

  • Rule 2—Glucose Range Check

When your sensor is in “Ready” status, you can input a BG value to calibrate your sensor. It will check whether your sensor glucose is in a valid range for calibration. The range is set to be 60 — 350 mg/dL (3.3—19.4mmol/L). 

  • Rule 3—Difference between Sensor Glucose and Finger Test Glucose Check

For security reasons, calibration won’t work when your Sensor Glucose has a very big gap with your Finger Glucose. The gap has to lie in [-90,90] mg/dL, or ±5 mmol/L.

  • Rule 4—Change Rate Of Glucose

The algorithm works only when your glucose level is stable for it’s hard to calibrate your sensor when the glucose is changing fast. The algorithm will work only when the glucose change rate is within [-2, 2] mg/dL/min, or ±0.11 mmol/L/min.

If any of the above 4 rules are violated, this entered BG point will be rejected for calibration. 

After all valid BG points (3 at least) are collected, the calibrate algorithm is run to get a new pair of parameters, slope and offset, which are going to be used to re-calibrate your sensor.

*The algorithm needs 3 BG points to initialize. It means that the calibration starts to work only after you input 3 valid BG points, by which all the above 4 rules are strictly followed. If more than 3 valid points are entered, the algorithm uses the latest 4 BG points to update the parameters for calibration.

*Calibration point 1 can be entered at a minimum of 1 hour after the sensor is activated. After the first valid BG point, at least a 15-minute gap is required to enter the next point for calibration.

*You can roll back to the Factory Calibration Model easily by double-clicking the calibration mode line on the Sensor Details page.

 

How to enable Calibration mode in Diabox.

Magic Code “GODMODE”

Press 5 times on the text calibration mode enter code “GODMODE” (BIG letters)
*Check that Calibration mode is enabled. *Press the icon in the Center bottom
*Enter your glucose levels from your glucose meter. Two blood glucose values are required for the initial calibration.
*You can delete or check history under the i-Algorithm – Calibration.

    Hello I have been using the bubblan with diabox. I cannot get it to work
    Have reset but nothing
    What is the app that is being used for android so I can start again

    1. Bubble flashtool?
      https://github.com/bubbledevteam/BubbleFW_FlashTool/releases/download/Bubble_FW_v3.1/BubbleFWFlashTool.apk

      Please email to support, the bubble should not just stop working like that.

      It doesn’t work no more with V:2021.08.20.1.

      So does reset
