  It’s highly recommended to calibrate your
individual stress index baseline once a month or whenever
you want to refer to your parameter in different situations.
To measure pulse and stress level:
1. Keep calm before and during measuring.
2. Press 
.
3. Put the tip of your thumb or index finger on the IR
sensor.
4. Wait for about 10
seconds until pulse
rate is shown (e.g.
100).
5. The LCD will display your 
stress
 level as follows:
ICON
BAR COLOR
MEANING
Green
Relaxed
Yellow
Normal
Red
Not relaxed
 Retry if failed (if no reading is showing within 1
minute the pedometer will escape from pulse mode). You
then press pulse rate button 
 again.
TIPS
Cold fingertips and cold air can affect the
measurement. You may need to warm your hands
before you start.
The sensor is sensitive to light sources. Cover the
entire sensor area with your fingertip to block all light.
Gently touch the pulse sensor; do not press hard.
Keep still and calm during measurement. Moving
about can affect the reading.
Wait the proper amount of time: Measurements can
take 6-12 seconds depending on the stability of the
signals received.
What is your stress index?
The stress index measurement is based on heart rate
variability, which indicates your involuntary nervous
system’s status.
