EXPOSURE OF THE FINGERS GLOW
Making the exposure of the glow from ten fingers, it is necessary to follow the rules:

1. The angle of the finger from the vertical should be in the interval of 10 - 40º. Preferably the finger should be positioned on its tip with the angle of 10º from the vertical.
2. The disposition of the finger axis relatively to the device axis is very important for the sector diagnosis. The axes of the electrode should be parallel to the sides of the device. After the finger is positioned properly, the light screen is closed and the exposure is carried out.
3. If there is no a sleeve with the hole for a finger, the position of the finger can be defined visually on the display or straight on the optical glass of the system. The finger image should be a little higher the screen center.
