The E-Meter (also electropsychometer and Hubbard Electrometer) is an electronic device used in Scientology that allegedly "registers emotional reactions". [1] After claims by L. Ron Hubbard that the procedures of auditing, which used the E-Meter, could help heal diseases, the E-Meter became the subject of litigation.
Jul 19, 2018 · In reality, the E-Meter is simply a device that costs five thousand dollars and only measures the resistance of the human body. It does this by having the subject hold two copper...
The device above is a Hubbard electro-psychometer (E-meter): a crude lie detector used by Scientology auditors (counselors) to examine a person's mental state. Scientologists claim the device allows people to "see a thought". In the hands of a trained auditor, they believe it can uncover "hidden crimes".
Jul 19, 2018 · E-Meters are essentially ways of measuring electrodermal activity, or the ebb-and-flow of electrical activity on the surface of the skin. For scientologists, this measurement is interpreted...

Fig. 1. Induction Type EnergyMeter. The basic principle of induction energy meter is electromagnetic induction. A thin disc of aluminium (or copper) is pivoted between the two Shunt and Series magnets and cuts the fluxes of both the magnets (Fig. 1). Hence two eddy currents are induced in the disc. The driving torque on the disc is produced as a re...
The single phase induction type energymeter has the following important parts : 1. Driving system, 2. Moving system, 3. Braking system, 4. Recording system.
The energy meter will register correct energy only if the shunt magnet flux lags the voltage exactly by 90°. This requires that the pressure coil should be highly inductive. If the angle is not 90°, it is to be adjusted by shading bands provided on the central limb of the shunt magnet. This is known as lag adjustment. Sometimes it is also called as...
Few errors which are common in induction energymeter are described below : Phase Error Normally the flux due to shunt magnet does not lag the supply voltage exactly by 90°. The reason being that the shunt coil has some resistance. Due to this, the angle of phase is less then 90°, as a result, the torque on the disc is not zero at zero power factor....
Some adjustments are done in the energymeter, so that the errors remain within limits. These adjustments are given below : Full load unity power factor (P.F.) adjustment The pressure coil is connected across the rated supply voltage. Rated full load current at unity power factor is also passed. The position of the brake magnet is adjusted, so that ...
Oct 2, 2013 · The basic Electronic Energy meter senses the current and voltage which signals from the circuitry, converts them in to the digital signal and makes necessary calculations to get the units of electrical energy which has been consumed.
