SAM.3 is a compact device, which functions self-sufficiently. Its form is similar to that of a cell phone, only slightly larger. A pin field, one backing electrode, a keyboard, a processor, batteries, a infra-red interface and a display are integrated into the body.

The patient gently presses the pin field of the measuring instrument to the skin of the forearm. He touches the backing electrode with one finger. Within 5 seconds there are impulses of voltage. With every impulse, 128 different electric currents flow through 128 pins. All in the mini-amp range. The data is then analysed statistically. The result delivers information on the relationship between coherency and incoherency in the organism. If one conducts several such readings in intervals, one can find out something about the dynamics in the system. This can be seen in a graph on the display: The Coherence Pyramid. Dots appear in the triangle, which represent the individual readings. If a dot lies in the zenith, then coherence is very good. The person is healthy. Or, he has outstanding prerequisites to regain his health. If the dots are in the lower area in the case of a patient, then the prerequisites of healing from chronic illness are absent. If the dots remain in the lower area on a long-term basis with a seemingly healthy person, then there is a higher risk of contracting a chronic illness.

The total time it takes from the beginning of the reading to the availability of the results is 10 to 12 seconds.

An extended variant of SAM.3 allows for the transfer of data between SAM.3 and computers. This function is in the interest of the detailed analysis of readings and extensive data management with a large number of patients.
