مقدمه
The JASTEK Ketone Breath Analyzer is a device designed to measure breath acetone concentration (PPM) as an indicator of ketosis. This manual provides essential information for the proper setup, operation, maintenance, and interpretation of results to assist users in monitoring their ketogenic state.

راه اندازی
1. نصب باتری
The device requires two (2) AAA alkaline batteries (not included). Open the battery compartment, insert the batteries according to the polarity indicators, and close the compartment securely.
2. Initial Device Exhaustion (First Use)
Before the first use, or if testing another person immediately after your own test, the monitor needs to be exhausted to clear any residual gases from production or previous tests. This ensures accurate readings.
- دکمه ON/OFF را به مدت 3 ثانیه فشار دهید تا دستگاه روشن شود.
- Wait for the 15-second countdown to complete. Do not blow into the device during this time.
- Once the countdown finishes, power off the device.
- Repeat this procedure 1-2 times (without blowing) before proceeding with your first actual test.
دستورالعمل های عملیاتی
1. Pre-Measurement Cautions
For the most accurate and consistent results, observe the following precautions:
- Avoid brushing your teeth, smoking, drinking, or eating any foods for at least 30 minutes before taking a test.
- Test your ketone levels under consistent conditions each time. The recommended time is right after waking up in the morning, before consuming anything (in a fasting state).
2. انجام تست
- دکمه ON/OFF را به مدت 3 ثانیه فشار دهید تا دستگاه روشن شود.
- The device will warm up and perform an internal exhaustion cycle.
- Once "START" is displayed on the screen, immediately blow into the mouthpiece for 5-6 seconds. Maintain a steady, gentle breath, similar to a "HAAaaaaaaa" sound, rather than a sharp whistle.
- The ketone meter will then analyze your breath.
- The reading will be displayed on the screen after approximately 10 seconds.

3. Interpreting Breath Acetone Concentration Readings (PPM)
The device measures breath acetone in Parts Per Million (PPM). Use the following guidelines to interpret your results:

| محدوده PPM | Ketosis Status |
|---|---|
| 0 ~ 1.9 PPM | Not in ketosis or just before ketosis. |
| 2.0 ~ 3.9 PPM | Very early stage of ketosis. |
| 4.0 ~ 9.9 PPM | Light status of ketosis. Body fat is burning at a low pace. |
| 10 ~ 39 PPM | Optimum level of ketosis. This is the stable fat burning zone, where fat is used as the main energy source. |
| 40 ~ 59 PPM | احتیاط! Approaching too high ketosis level. Adjust your level to under 40ppm. |
| 60 ~ 99 PPM | خطر! In too high level of ketosis. Risk of Ketoacidosis. |

تعمیر و نگهداری
1. Mouthpiece Care
The mouthpiece is designed to be replaceable for hygiene. Ensure it is securely attached before each use. For cleaning, gently wipe the mouthpiece with a clean, damp پارچه دستگاه را در آب غوطه ور نکنید.

2. ذخیره سازی
Store the device in a cool, dry place away from direct sunlight and extreme temperatures. Keep it out of reach of children.
عیب یابی
- Inconsistent or Unexpected Readings:
- Ensure you have performed the initial device exhaustion procedure as described in the Setup section.
- Verify that you are following all pre-measurement cautions (no eating, drinking, smoking, or brushing teeth 30 minutes prior).
- Confirm that you are blowing steadily for the required 5-6 seconds immediately after "START" appears.
- سطح باتری را بررسی کنید؛ باتریهای کم میتوانند بر عملکرد تأثیر بگذارند.
- روشن نشدن دستگاه:
- اطمینان حاصل کنید که باتری ها به درستی با قطبیت مناسب نصب شده اند.
- باتریهای قدیمی را با باتریهای آلکالاین AAA جدید جایگزین کنید.
- Press and hold the ON/OFF button for the full 3 seconds.
- Mouthpiece Detaches Easily:
- Ensure the mouthpiece is firmly pushed onto the device.
- If the mouthpiece is worn or damaged, replace it with a new one.
