I read that a famous doctor (now deceased) did an experiment placing one of the wires of an ohm meter on a person's finger and another wire to one of the person's toes on the opposite side. He then placed a ceramic magnet over the body. The ohm meter remained the same. He then placed different foods under the south pole of the magnet. Occasionally, he would find a food that changed the ohm meter reading. He found that the foods that changed the reading were foods that the people had sensitivity to. I am interested in trying this experiment and would like to know which brand and model of ohm meter to get. I have read that analog meters might be more convenient to use than multimeters. I would also need longer leads (like 4 ft.) which I haven't been able to find. Thanks!
