How the Watch Works

It is useful to understand the basics of how the S-Pulse™ sensing
technology – as it will perform differently on people of different age,
skin type, body type, EKG or electro-cardiogram signal strength, among
others.
The S-Pulse™ technology measures the electronic signals that pass
through your body – that result from the beating of your heart. Many
are familiar with the EKG waveform – from either personal experiences
while at the hospital, or from popular television medical shows. It is this
same signal that passes through your body. This measurement is
obtained by the Watch's three metal sensors. The back metal plate of
the Watch wrist is actually a primary sensor that measures these
electronic signals off your arm.
The 'EKG' measurement is done when you place your fingers from one
hand on the top sensor on the Watch that is attached to your opposite
arm. This creates a loop across your body that the Watch can now read.
• The Sportline Solo 910 Heart Rate Watch must be attached to your wrist
in order for the Heart Rate Measure function to work.
