Difficulties of use

1. DIFFICULTies of use
1.2 The sensor is dirty

If the back of your watch is dirty (soil, sun cream etc.), this may affect the sensor. Your HR500 watch is waterproof. You can clean it by rinsing it in clean water.

1.3 You practice a non-repetitive sport

Measuring your heart rate with a monitor on the wrist (optical reader) is optimal for sports with repetitive movements such as running, or using a cross trainer or exercise bike. It is not recommended to use a heart-rate belt for fitness class, body-building, etc.

1.4 The weather is very cold

Blood vessels reduce in size when the weather is cold, making reading the heart rate more difficult.Blood circulation improves as you work out, improving your heart-rate measure.

1.5 Interval training

The watch is not very close to the heart so the blood will take some time to flow to your wrist. For interval training, there will be a delay in the time it takes to measure the signal. For very short minute-long intervals, it will be difficult for the watch to measure the maximum heart-rate.

1.6 Tattoos

If you have tattoos on the area where the watch is located, you may notice errors in your heart rate measurement.

1.7 Using in water

The heart-rate monitor does not function correctly in water.
As a reminder, the watch has an IPX6 waterproof level (shower).

1.8 Other reasons

The blood vessels in your right and left arm may be different. If the results on one arm are not optimal, try the other arm.

Data accuracy

4.1 Accuracy of step and distance measurement.

Our algorithm of step counting is based on wrist movement. The accuracy depends on your daily activity.

You will see differences with other step counting systems (phone, other smartwatch brands…) because each manufacturer chooses its own algorithm. Some erratic movements can impact accuracy:
- Step counting starts after 10 steps minimum. This is done in order to exclude erratic movements.
- Putting the hand on the pocket or hold a troller wil affect accuracy as well.
-Information like gender, age, height and weight are important for distance and calories accuracy
- The way you tighten the watch on the wrist also affect the accuracy. The tightest is it, the better accuracy will be.
- Other factors can impact things like ground, slopes, vibration of the car or train... 

4.2 Accuracy of sleep data.

As for step counting, the way you wear the product at night will impact accuracy. Please tighten the strap to ensure a good measurement.

4.3 Accuracy of heart rate monitor measurement.

We have tested the latest optical technologies to bring you the most reliable technology. Certain factors may nevertheless degrade the heart rate measurement, in particular the positioning of the watch on the wrist.

Your watch should fit properly, above the wrist bone, while still being comfortable. If the tightening is too loose, then the watch will not be able to measure the signal correctly. See the section "How do I position my watch correctly on my wrist?"

Find other factors that can degrade the measurement in the "DIFFICULTIES OF USE" section.
