如何对Apple Watch的心率传感器进行故障排除

The Apple Watch is a great fitness-tracking device because it can record both your GPS position and your heart rate. However, if for some reason you’re not getting any heart rate readings or it’s not being tracked consistently, here’s what to do.

Apple Watch是一款出色的健身追踪设备，因为它可以同时记录您的GPS位置和心率。 但是，如果由于某种原因您没有获得任何心率读数或无法持续对其进行跟踪，请执行以下操作。

Apple Watch心率传感器如何工作 (How the Apple Watch Heart Rate Sensor Works)

The Apple Watch uses green LEDs paired with photodiodes to track the blood flow through your wrist. Blood appears red because it reflects red light and absorbs green light (that’s physics for you!). So, by measuring how much green light is absorbed a few hundred times per second, your Apple Watch can track when your heart is beating. It can detect a heart rate range of between 30 and 210 beats per minute.

Apple Watch使用绿色LED和光电二极管配对，以跟踪通过手腕的血液流动。 血液显示为红色，是因为它反射红光并吸收绿光(这对您来说就是物理学！)。 因此，通过测量每秒几百次吸收多少绿光，Apple Watch可以追踪心脏跳动的时间。 它可以检测到每分钟30到210次跳动之间的心率范围。

The Apple Watch also uses infrared LEDs for background heart rate tracking.

Apple Watch还使用红外LED进行背景心率跟踪。

To force your Apple Watch to check your heart rate, put it on, and open the “Heart Rate” app. If you get a reading after a few moments, it means the problem is most likely tied to how you use or wear your Watch.

要强制Apple Watch检查您的心律，请戴上它，然后打开“心律”应用程序。 如果稍等片刻即可获得读数，则说明问题很可能与您使用或佩戴手表的方式有关。

If you don’t get a reading, the heart rate sensor may be broken—or your Watch may need to be reset. Skip ahead to the section on resetting a Watch for instructions on how to do that.

如果没有得到读数，则心率传感器可能会损坏，或者可能需要重置手表。 跳至有关重置手表的部分，以获取有关如何执行此操作的说明。

确保开启心率追踪 (Make Sure Heart Rate Tracking Is On)

To get background heart rate readings, Wrist Detection must be enabled. On your iPhone, open the Watch app, go to “Passcode,” and check to see if “Wrist Detection” is turned on.

要获取背景心率读数，必须启用“手腕检测”。 在您的iPhone上，打开Watch应用程序，转到“密码”，然后检查“手腕检测”是否已打开。

If you’re relying on your Apple Watch to track your heart rate during workouts, you can’t use the Power Saving Mode. Open the Watch app on your iPhone, go to “Workout,” and make sure the Power Saving Mode is disabled.

如果您在锻炼过程中依靠Apple Watch追踪心率，则无法使用省电模式。 在iPhone上打开Watch应用，转到“锻炼”，并确保禁用了节电模式。

检查乐队和位置 (Check the Band and Positioning)

To consistently track your heart rate, your Apple Watch needs to be able to detect it. If it’s not correctly positioned on your wrist, it’ll struggle to get reliable readings.

为了始终如一地跟踪您的心律，您的Apple Watch必须能够检测到它。 如果未正确放置在手腕上，将很难获得可靠的读数。

Apple recommends that your Watch is “snug, but comfortable.” It should stay fixed in place while you exercise, but it shouldn’t cut off blood flow. You might need to tighten it a little bit for workouts, especially if you don’t like the feeling of a tight band around your wrist throughout the day.

苹果建议您的手表“舒适但舒适”。 运动时，它应固定在适当的位置，但不应切断血液流动。 在进行锻炼时，您可能需要稍微收紧它，尤其是如果您全天不喜欢手腕上绑紧绷带的感觉时。

While what band you use shouldn’t affect the heart rate reading, it can affect how comfortable your Watch is when you wear it tight enough to get a good heart rate reading. The Sports Band, Sports Loop, Nike Sports Band, and Nike Sports Loop are all designed to be comfortable when worn tightly during exercise. The Sports Loops, in particular, are easy to adjust as needed.

虽然您使用的腕带不会影响心率读数，但是当您戴得足够紧以达到良好的心率读数时，它可能会影响手表的舒适度。 Sports Band，Sports Loop，Nike Sports Band和Nike Sports Loop均设计成在运动时紧紧穿着时舒适。 特别是运动循环，易于根据需要进行调整。

Other bands, like the Leather Loop or Steel Link Bracelet, just aren’t as nice when you’re sweating.

其他乐队，例如Leather Loop或Steel Link手链，在出汗时效果不佳。

Apple recommends you wear your Watch faceup on the top of your wrist. However, because of my hairy wrists, I actually got more consistent heart rate readings putting it on the underside of my wrists when I run. This shouldn’t be an issue for most people, but give it a shot if you’re struggling to get steady readings while running.

Apple建议您将Watch正面朝上戴在手腕上。 但是，由于手腕毛茸茸，当我跑步时，我的心率读数实际上更加一致。 对于大多数人来说，这不应该是一个问题，但是如果您在跑步时难以获得稳定的读数，可以尝试一下。

可能影响锻炼心率追踪的因素 (Factors That Can Affect Workout Heart Rate Tracking)

A few factors can affect your Apple Watch’s ability to measure your heart rate.

一些因素会影响Apple Watch测量心律的能力。

Movement, especially dynamic movement, makes it harder for your Watch to measure your heart rate. It has an easier time tracking your heart rate during steady movements like walking or running, than during erratic workouts like boxing.

运动，尤其是动态运动，使您的手表更难测量心率。 与步行或跑步等不稳定锻炼相比，它在跟踪或跑步等平稳运动中跟踪心率的时间要容易得多。

The LEDs and sensors are located on the bottom of the Watch. If dirt, grime, or sweat builds up, it can make them less effective. Give the bottom of your watch a wipe with a damp clean cloth.

LED和传感器位于手表的底部。 如果堆积了污垢，污垢或汗水，可能会使它们的效力降低。 用干净的湿布擦拭手表底部。

Also, there are factors that make your heart rate harder to measure. The sensors detect surface blood flow and if blood flow is reduced to your wrist, it’s harder for the Watch to get a read. Cold weather is a big one here; theoretically, so are overhead gymnastic movements or any lifting that uses compression straps on your arms.

另外，有些因素会使您的心率难以测量。 传感器检测表面的血流，如果流到手腕的血流减少，则手表很难读取数据。 这里寒冷的天气很大。 从理论上讲，高架体操运动或任何在手臂上使用压缩带的举重运动也是如此。

重置您的Apple Watch (Reset Your Apple Watch)

If after trying all the above suggestions, your Watch still fails to accurately detect your heart rate, the next step is to try resetting it.

如果尝试了上述所有建议后，手表仍然无法准确检测到您的心律，则下一步是尝试将其重置。

To reset a Watch, open the “Settings” app and go to General > Reset > Erase All Content and Settings. Enter your passcode, and follow the onscreen prompts to erase the Watch completely.

要重置手表，请打开“设置”应用，然后转到常规>重置>删除所有内容和设置。 输入密码，然后按照屏幕上的提示完全删除手表。

Then, using the “Watch” app on your iPhone, you’ll need to set it up again.

然后，使用iPhone上的“观看”应用，您需要再次进行设置。

与苹果联系 (Contact Apple)

If a hard reset doesn’t fix your Apple Watch, it’s possible that the sensor is broken. Contact Apple as the company may repair or replace it for you, if it’s still under warranty.

如果硬重置无法修复Apple Watch，则可能是传感器损坏。 如果苹果仍在保修期内，请与苹果联系，由苹果公司为您维修或更换。
