4.4 Display Symbols Explained
Image Description: This detailed diagram illustrates the meaning of each symbol on the Yuwell blood pressure monitor's display. It identifies icons such as the battery power indicator, user A/B icon, records number, an "OK" symbol for correct cuff wrapping detection, an IHB (Irregular Heartbeat) prompt, and symbols for movement error indication and inflation/deflation. This guide is crucial for understanding the monitor's feedback during and after measurements.
Familiarize yourself with the display symbols to understand the monitor's status and readings:
- Battery Power Icon: Indicates remaining battery life.
- User Icon (A/B): Shows which user's data is being displayed or recorded.
- Records Number: Displays the current measurement number in memory.
- Cuff Wrapping Detection (OK): Confirms correct cuff placement.
- IHB Prompt: Indicates detection of an irregular heartbeat.
- Movement Error Indication: Alerts if body movement occurred during measurement.
- Inflation/Deflation Arrows: Shows when the cuff is inflating or deflating.
5. Setup
5.1 Battery Installation
- Open the battery compartment cover on the back of the monitor.
- Insert the 4 AA batteries provided, ensuring correct polarity (+ and -).
- Close the battery compartment cover securely.
The device can also be powered via the USB cable (adapter not included) for continuous use without batteries, or as an alternative power source.
5.2 Connecting the Cuff
- Locate the air tube connector on the cuff.
- Insert the air tube connector firmly into the air jack on the side of the main monitor unit.
- Ensure the connection is secure to prevent air leakage during measurement.
6. Operating Instructions
6.1 Before Measurement
- Avoid eating, drinking alcohol, smoking, exercising, and bathing for 30 minutes before measurement.
- Rest for at least 5 minutes before taking a measurement.
- Sit in a comfortable position with your back supported and feet flat on the floor.
- Place your arm on a flat surface so the cuff is at heart level.
6.2 Applying the Cuff
- Slide your arm through the cuff loop. The air tube should run down the inside of your arm.
- Position the cuff so the bottom edge is approximately 2-3 cm above your elbow.
- Wrap the cuff snugly around your upper arm, ensuring it is not too tight or too loose. The "OK" symbol on the display will confirm correct cuff wrapping.
6.3 Taking a Measurement
- Press the Power/Start button once. The cuff will begin to inflate automatically.
- Remain still and silent during the measurement. Avoid talking or moving your arm. The monitor's movement detection feature will alert you if movement occurs.
- Once the measurement is complete, the cuff will deflate, and your Systolic, Diastolic, and Pulse readings will be displayed on the screen.
- If an irregular heartbeat is detected, the IHB symbol will appear.
- The monitor will automatically store the readings in the selected user's memory.
6.4 Dual User Mode and Memory Function
Image Description: This image illustrates the dual user mode feature of the Yuwell blood pressure monitor. It shows two distinct memory groups, labeled "USER A" and "USER B," each capable of storing up to 74 sets of measurement data. The display provides a clear view of recorded dates, systolic, diastolic, and pulse readings for each user, allowing for easy tracking of blood pressure trends over time.
The monitor supports two users, each with 74 memory groups. This allows two individuals to track their blood pressure trends independently.
- Selecting a User: Before measurement, press the User A/B button to switch between User A and User B.
- Viewing Memory: Press the Memory button to cycle through stored readings. The monitor can also display the average of the last three measurements.
7. Maintenance
7.1 Cleaning
- Wipe the monitor unit and cuff with a soft, dry cloth.
- If necessary, use a cloth lightly dampened with water or a mild detergent. Do not use abrasive cleaners or immerse the device in water.
- Ensure the device is completely dry before storage or next use.
7.2 Storage
- Store the device and cuff in the provided storage bag.
- Keep the monitor in a cool, dry place, away from direct sunlight, extreme temperatures, and humidity.
- Remove batteries if the device will not be used for an extended period to prevent leakage.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Monitor does not power on. | Batteries are dead or incorrectly inserted. | Replace batteries or check polarity. Ensure USB cable is connected if using external power. |
| Error message displayed. | Cuff not applied correctly, excessive movement during measurement, or air leakage. | Re-apply cuff snugly. Remain still and silent. Check cuff connection to the monitor. |
| Readings are inconsistent. | Improper measurement posture, talking during measurement, or taking measurements too frequently. | Ensure proper posture and rest before measurement. Wait at least 3 minutes between measurements. |
| IHB symbol appears frequently. | Indicates detection of an irregular heartbeat. | This is a warning, not a diagnosis. Consult a physician if this symbol appears frequently. |
