Using the Polar E600 in a Water Environment
The Polar E600 is water resistant to 160 feet/50 meters.
Heart rate measurement in a water environment is technically
demanding for the following reasons:
• Pool and salt water can be very conductive and may short
circuit the electrodes so that EKG signals cannot be detected
by the transmitter.
• Jumping into the water or strenuous muscle movement during
competitive swimming may cause the transmitter to slip out of
place.
• The EKG signal strength varies depending on the individual’s
tissue composition. The percentage of people who have
problems in heart rate measuring is considerably higher in a
water environment than in other use.
Polar Heart Rate Monitor and Interference
Electromagnetic Interference
Disturbances may occur near high voltage power lines, traffic
lights, overhead lines of electric railways, electric bus lines or
trams, televisions, computers, cars, electric motors, bike
computers, some motor driven exercise equipment, cellular
phones, antennas, invisible fences, or when you walk through
electric security gates. Interference or "crosstalk" can also be
caused by the heart rate signal from another Polar HRM wearer.
