Activity: 24/7 activity measurement
24/7 Activity Measurement registers all effective active motion and shows it graphically. With this function you can see the benefits of what you’re doing. 24/7 Activity Measurement converts body movement into digital data that is combined with information about the user, including age, gender, height, and weight. Then its fitness calculations transform the data into active time, calories, active steps, distance, and more. 24/7 Activity Measurement is primarily for walking, jogging, and running. |
Basic: Water resistant
30m
Polar products may be worn when swimming. They are not, however, diving instruments. To maintain water resistance, do not press the buttons of the product under water. When measuring heart rate in water, you may experience interference for the following reasons:
Pool water with high chlorine content, and seawater are very conductive. The electrodes of the transmitter may short-circuit, preventing ECG signals from being detected by the transmitter.
Jumping into water or strenuous muscle movement during competitive swimming may shift the transmitter to a location on the body where ECG signals cannot be picked up.
The ECG signal strength is individual and may vary depending on the individual’s tissue composition. Problems occur more frequently when measuring heart rate in water.
In the watch industry water resistance is generally indicated as meters of water pressure, which means static pressure of water at the level in question. Polar uses this same indication system. Water resistance of Polar products is tested according to International Standard ISO 2281. Every Polar device that has water resistance indication is tested before the delivery to stand water pressure.
Polar products are divided into three different categories according to their water resistance. Check the back of your Polar product for the water resistance category, and compare it to the chart below. Please note that these definitions do not necessarily apply to products of other manufacturers.
When performing any underwater activity, the dynamic pressure generated by moving in water is greater than the static pressure. This means that moving the product under water subjects it to a greater pressure than if the product were stationary.
When it says "water resistant" it means alright to be exposed to wash splashed, sweat, raindrops.
When it is a Polar Wearlink, and says "water resistant up to 30m" it means alright to be exposed to wash splashed, sweat, raindrops, bathing, swimming.
When it says " water resistant up to 50m" it means alright to be exposed to wash splashed, sweat, raindrops, bathing, swimming.
When it says "water resistant up to 100m" it means alright to be exposed to wash splashed, sweat, raindrops, bathing, swimming and skin diving with snorkel (no air tanks). |
