4. Relax and put the

index finger on the
pulse sensor.
5. Wait for about 10 seconds until the word FINISH
appears on the LCD panel.
6. Repeat 3-5 if the
calibration fails.
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.
