TONE ARM (12) — Term from SntMaster Dictionary

TONE ARM (12)

ScnMaster

a control lever on the E-Meter. The tone arm registers density of mass in the mind of the preclear. This is actual mass, not imaginary, and can be weighed, measured by resistance, etc. Therefore, the tone arm registers the state of the case at any given time in processing. As a person is processed, mental mass shifts and dissipates, and the auditor moves the tone arm to compensate for these fluctuations. TA is also used as an abbreviation for tone arm action. Tone arm action refers to the measurement of how much the auditor had to move the tone arm downward (counterclockwise) during a session, and is used as an index of case improvement in the preclear. Tone arm action is measured in units called divisions. A division is the distance between any of the two consecutive numbers appearing on the tone arm dial. See also E-Meter in this glossary.
