The two main ones being and addition or reduction of mass (ridge
*) which modifies the overall resistance of the body (Rx) holding the "meter's" electrodes and/or an addition (feeding) or removal (sucking) of electrical energy in the Rx circuit by the "thetan" or by induction due to an electromagnetic "mass" moving around within the individual's field or, also, by electromagnetic signals from TV, radio, cell towers, cell phones, truck and cars passing by, etc...
The "sophistication" in the e-meter is mainly due to the latter with additions of filters to eliminate environmental "parasites"/interferences. These are the "frequency filters" added to the basic Wheatstone Bridge of the e-meter circuit.
The e-meter operator can only see what happens on the meter unless also "psychic" or a very keen observer able to notice subtle changes in the individual holding the meter's electrodes.
LRH being both psychic and gifted with a very keen sense of observation, realized that most "auditors" weren't or wouldn't be either and threw the idea -- for anyone to grab on -- of being able to measure what was happening to "ridges"
* in an individual's field when these "ridges" are re-activated ("looked" at or displaced) blown or vanished (as-ised).
Mathieson grab the ball and ran with it and LRH being able to "see" what was happening in people's field as well as corroborate the subtle energy behaviour with physical observation of the "Rx" body holding the "cans"/electrodes was able to modify, suggest improvements and calibrate the e-meter down to what was only necessary to measure or "read" on its dial.
So, being "In Session" and therefore being "interested in one's own 'case' and willing to talk to the auditor" rather than playing with one's energy field to "see" what it would do on the meter is the optimum condition for the use of an e-meter as a tool to help locate where a "ridge"
* is causing troubles in one's life.
* RIDGE,
1. it's a standing apparent motionlessness of some kind or other, an
apparent solidity, an apparent no-outflow—no-inflow, that's a ridge. Flows
have direction. Ridges have location. (5904C08)
2. a ridge is caused by two energy flows coinciding and causing an enturbulence of energy, which, on examination, is found to take on a characteristic which in energy flows is very like matter, having its particles in chaotic mixture. (Scn 8-80, p. 43)
3. a ridge is formed from two [opposite] flows and these two flows hitting will pile things up. (PDC 18)
4. a ridge is essentially suspended energy in space. it comes about by flows, dispersals or ridges impinging against one another with a sufficient solidity to cause an enduring state of energy. (Scn 8-8008, p. 18)
5 . a solid body of energy caused by various flows and dispersals which has a duration longer than the duration of flow. Any piece of matter could be considered to be a ridge in its last stage. Ridges, however, exist in suspension around a person and are the foundation upon which facsimiles are built. (Scn 8-8008, p. 49)
6 . facsimiles, or pictures, of motion. (Scn 8-80, p. 45)
7 . areas of dense waves. (Scn 8-8008, p. 78)
8 . electronic densities. (Scn Jour 6-G)

Ridge
Most of the time, the counter intention to one's intention is long gone but the created ridge is still there. When, once again, one flows out such an intention (or "looks" at it as directed by a question), that intention "hits" the ridge and its initial "counter intention" is reactivated and confused as being in "present time." Conversely, when a similar "counter intention" is encountered, and although the "intention" is long gone, that "counter intention" also "hits" the ridge and the initial intention "wakes up"....
Accordingly, most people are kept in the "jails" of the past... whence prejudices, antagonisms, conflicts, etc. are kept alive... many a "gut's feeling" are borne out of those "ridges"....
