How the Watch Works
It is useful to understand the basics of how the S-Pulse™
sensing technology – as it will perform di erently on people of
di erent age, skin type, body type, ECG 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 ECG 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
o your arm.
The ‘ECG’ measurement is done when you place your ngers
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 915 Heart Rate Watch must be attached to your
wrist in order for the Heart Rate Measure function to work.
