Using the principles of acupuncture medical and dental physician German Helmut Schimmel devised a machine of testing the body's resistance to foods in addition to checking vitamin and mineral shortages in the body back in 1984.

System is known as Bio-Electronic Regulatory Medicine (BER). Works on the theory of utilising the acupuncture pressure points on the fingers to measure resistance in the body to substances (foods, airborne, drinks, etc), which can be the route cause of problems in every day life.

Manufactures by German Med-Tronic the machine used is the RMIOS. During nine years in practise john Neal has tested babies as young as eight months old, to grandmothers aged eighty-four years old.

By placing samples of various substances (foods, airborne, drinks, etc) one by one into a special container (honeycomb) connected to the machine, practitioner can determine if the patient has sensitivity to the substance tested. Electrode is held in one hand, connected to the machine. Probe is placed on an acupuncture pressure point opposite side of the body this creates a circuit with the machine.
