Performing measurements

Rest your elbow on the table. Lower your hand so that it hovers 1 inch above the sensor. You can get ideal contact to the sensor by letting the hand rest on it with its own weight. Do not use the muscles of the arm to lift the hand or to press it onto the sensor. Since your blood contains antioxidants the effective antioxidant level will change if you press against the sensor. The sensor has a function that compensates the effect of the contact force. So, you do not need to worry to get a perfect contact. But if only the weight of your hand and arm is applied you still get a little bit better result. Pushing blood out of the skin will make the measurement of heart rate variability complete impossible.

Sitting position - sensor on the table

Put your elbow on the table - no extra force when measuring

Gently place your right hand on the sensor using the groove to precisely align your hand. By always measuring the exact same point, you can properly see the effects of diet and lifestyle changes.

It is important to keep your hand steady during the measurement. The sensor takes a number of different measurements and compares the results. If the hand moves between measurements or the contact with the sensor varies, the comparison works less well.

Use the groove to precisely align your hand

Do not move your hand while measuring

Avoid bright light on your hand during measurement (sunlight, bright artificial light). Cover your hand if necessary.

Bright light can get through your hand. You can try this by turning on your smartphone's LED flashlight and placing your finger on it. You can see that especially red light can get through your finger. The sunlight is even stronger and can get through all hands. For this reason, the Biozoom sensor refuses to measure in direct sunlight. If you want maximum precision, you can help the sensor by making sure that no bright light hits the back of your hand while measuring. Normal ceiling lights are usually not a problem.
