Here’s how the newest tech works…

The newest modern bridge instrument has a digital display to allow for easy, automated use in all auditing environments. Like all modern instruments, bridges can be connected to a computer and other equipment to export readings and allow external inspection.

The newly introduced distortion meter is actually a level meter with two parallel switchable circuits at the input. The first circuit measures the total signal at the system output. (For low distortion, this is close to the fundamental). This value is set to a reading of 100% or equivalent to 0dB. The second circuit is a high pass filter that removes the fundamental frequency (as much as possible). This can be a notch filter that passes everything but the fundamental frequency at other frequencies (including the presence of harmonics) with negligible attenuation. Alternatively, if the distortion products are at higher frequencies, a high pass filter can be used if its cutoff frequency is steep enough not to affect the expected distortion products. This feature was included to accommodate less than cooperative pre-clears.

The mechanism of the Mark IX uses a moving spool that carries the needle and rotates under tension on pins or ribbons. The coil rotates in a constant magnetic field and is held in place by thin coil springs, which also serve to carry current to the voice coil. It provides a proportional measurement, not just a bearing, and the error is independent of the orientation of the gauge. Instead of balancing the bridge, values ​​could be read directly from the instrument’s scale, making measurement quick and easy. No more dependency on false floating needle readings!

The basic moving-coil meter is suitable for DC current measurements only, typically in the 10 μA to 100 mA range. It can easily be adjusted to read larger currents using shunts (resistors parallel to the movement of the base) or voltages using series resistors called multipliers. Previously, it was recommended that the Tone Arm value with the needle at the set-point should be between 2.0 and 4.0. A value of 4.5 is considered barely passing; 5.0 or higher is a failure, as is any value below 2.0. This is no longer necessary as the Mark IX automatically adjusts during the calibration at startup.

In simple terms, there are two terminals which carry current to and from the meter, while the other two allow the meter to measure the voltage across the resistor. With this arrangement, the current source is connected in series with the resistance to be measured via an external pair of terminals, while the other pair is connected in parallel with the galvanometer, which measures the voltage drop.With this type of meter, any voltage drops due to the resistance of the first pair of wires and the resistance of their contacts are ignored by the meter. This four-terminal measurement technique is literally a Double-Quantum leap from the previous Mark Ultra VIII E-Meter, making measurements in perfect alignment with LRH policy.

The brand new spectrum analyzer measures the amplitude of the input signal as a function of frequency over the entire frequency range of the instrument. The main purpose of the spectrum analyzer is to compensate for unexpected geomagnetic earth anomolies or sunspot maximums which will cause disruption in radio transmissions and aplitude variations in the coronal loops. 


Glide Sweep
A glide sweep (or chirp) is a continuous signal whose frequency logarithmically increases or decreases over time. The advantage of the Glide Sweep is that it allows the user to shorten the duration of the signal without losing frequency resolution in the results. This allows for instant recognition of the Theta Bop and allows the counselor time to resist an incoming spirit that could interrupt the session.

Step Sweep
A step sweep increases or decreases a variable input parameter (frequency or amplitude) in discrete steps. After each change, the counselor waits for a stable reading to be found before proceeding to the next step. Step scaling is linear or logarithmic. As it is not possible to predict the acclimatization time of different subjects, the duration of the progressive scan cannot be precisely determined in advance. To determine amplitude or frequency response, Step Sweep automatically adjusts for body reactions caused by body motion, such as the preclear yawning, coughing, moving around in the chair, or lifting a finger off the cans.

Time scan
In the time scan, the x-axis represents the time. Here, too, the y-axis represents the measured value, for example the amplitude. The development of the measured value is observed over time.For example, how does the test subject’s reaction change over time?

This newest technology takes all the worry out of auditing and brings L. Ron Hubbard’s Scripture clearly into focus, “The E-meter is never wrong. It sees all; it knows all. It tells everything.”
