Blood pressure measurements on my HUAWEI WATCH D/D2 fail or generate no results

• If the watch has been powered off due to low battery or disconnected from your phone for a long time, the time display may be incorrect, which can result in no blood pressure readings.
• It is recommended that you reconnect or pair your watch with the Huawei Health app. After the Bluetooth connection is restored, measure your blood pressure again. This can resolve issues caused by not using or connecting the device for a long time.

• The measurement range of the pump is 0–300 mmHg (0–40 kPa). Pressure values outside this range cannot be measured.
• It is recommended that you pause the measurement, take a short break, adjust the watch strap to ensure it is worn snugly, and try measuring again.
  

  During measurement, make sure that the device is level with your heart, relax your body, and avoid speaking or moving.

When using the blood pressure measurement feature, pay attention to the following:

1. Correct wearing position

   Wear the watch on a wrist without tattoos or scars. Ensure that the watch is worn about two fingers' width (approximately 3 cm) from the palm, and avoid wearing it over the ulna styloid protrusion (your wrist bone).

   

2. Precautions

• Wrist hair may affect measurement accuracy. It is recommended that you trim the hair.
• Stay still during the measurement and make sure that the device is level with your heart.
• Ensure that the watch strap is snug but not too tight (you should be able to fit one finger between the strap and your wrist).

If the issue persists, try measuring on the other wrist or clean the sensor area.

In this case, perform the following steps:

1. Correct measurement posture

   Bend your elbow at a 90-degree angle and gently place your palm against your chest. Use your other hand to support your elbow and make sure that the watch is level with your heart. Your wrist should be naturally relaxed. Do not clench your fist. Keep your feet flat on the ground.

2. Requirements for the measurement environment
   • Sit and rest for at least 5 minutes before the measurement. Avoid talking, coughing, or moving your body. Ensure that the watch strap is neither too tight nor too loose.
3. Precautions
   • A cold wrist can impede blood flow, leading to a weak pulse and measurement failure. In such cases, warm your wrist and try again.
   • If you have a very weak pulse due to severe anemia, do not use this product to measure your blood pressure.
   • Blood pressure measurements might not succeed or produce any result due to unstable posture caused by conditions such as Parkinson's disease, the aftereffects of cerebrovascular disease, and frequent premature beats.
   • Severe arteriosclerosis may cause blood pressure measurements to fail or generate no results.
   • An abnormally low or high heart rate (below 40 or above 180 bpm) can cause blood pressure measurements to fail or generate no results.

   If the issue persists after several attempts, clean the watch sensor and update your watch. If the issue remains unresolved, take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.

Arrhythmia could cause measurement failure or inaccurate results. Try having someone else use the watch to see if it works properly.

If the issue persists or the airbag fault is beyond your capability to handle, take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
