How to take care of your chest strap
A chest strap is an important part of every sport tester. Therefore, it should be kept in good condition. In order for it to work as good as possible, it’s required to take care o fit properly.
You may ask: „Why?“ You have to understand some important features of a chest strap. It doesn’t have a switch-off button. Therefore, it turns on and off automatically when it notices a higher electrical conductivity. When you put the strap on your body, it turns on automatically. After you finish your activity and the chest strap doesn’t notice any electrical conductivity in the next 15 minutes, the chest strap turns off on its own. That helps the battery life.
The problem comes when you finish training and your chest strap is all sweaty and you roll it down and put it in your bag, along with your wet towel. The strap is due to a higher electrical conductivity still on, and the battery is dying. This case is not unusual. It also happens that you roll down the chest strap with a wet belt and you put it in your bag. Again, the chest strap may not turn off because it notices a higher electrical conductivity.
If you don’t wash your chest strap every time you use it, salt from your sweat stars to settle there. And if the salt reaches certain concentration, the strap can restrain water from the air, and it becomes permanently conductive. Therefore, the strap sensor stays turned on and the battery life gets shorter.
How should you take care of your chest strap?
If it’s possible, remove the sensor from the strap (you can do that, for example, with Polar Wearlink, Suunto Comfort Belt, Garmin Premium HR Belt, etc.), right after you finish training. Therefore, the chest strap stops capturing conductivity because the touch spaces are separated from the sensor itself, and it turns off. A textile strap with contact spaces can be washed in hands with warm water and then dried. If the sensor can’t be removed from the strap (for example, Sigma, Beurer and other cheaper sport testers), it’s necessary to wash and dry the chest strap after training, especially in places with contact spaces. From time to time, you should also put the strap in a washing machine.
Washed and dried chest strap should be kept in drought. A dry strap in a wet towel or bag can be turned on again, due to a higher humidity.
