1. Put your device on an inflated bag.
2. Press "PRESS to calibrate" button and wait until the "calibration ... please wait" communicate will disappear.
3. After calibration process is done gently place a coin in the middle of the top/bottom area of the phone and once again wait until it is done.
4. Gently place an object you would like to weigh on the coin and wait until the result shows up on the wheel.
IMPORTANT TIPS:
-Always put the bag on the "still" surface like floor or table (avoid moves which could induce vibrations of the surface).
-Do not touch the bag or the phone while placing coin and objects.
