Introduction:
This
is the
venerable, affordable and handy Gauss Master AC
emf meter / gauss meter.
This is a great little AC milligauss meter in it's own right and a nifty " platform " for an
array of devices that are very useful to many types of hobbyist. It is easily converted to
external antennas, audio outputs and power on / off switches.
The intended application for the Gauss Master , initially , was to measure environmental
EMF AC radiation levels. This radiation was commonly associated with computer screens
and electrical power wiring in houses and offices. Ghost hunters, paranormal hobbyist,
UFO hunters and government conspiracy people have adopted the Gauss Master for
their own purposes too. The gauss master " mods " section of this site has useful
Gauss Master changes to improve the meters applications for " all " the hobbyist
that might use this meter.
The Gauss Master empowers hobbyist with " portable / mobile " ULF and DC
magnetic wave detection and allows recording of these waves with the possibility
of simplification of the recording process ( usually done with a laptop and spectrum
display program , see the signal recording section for more on this ) . It's vco / meter
circuit is invaluable as a " hands off " meter ( one that you don't have to hold or
look at to use ) to boot. Because of the handy vco audio oscillator, this device
can allow a person to detect and " hear " signals that are below the range of human
hearing , by " up converting " them to an audio tone when detected. A person couldn't
go down to Radio Shack and buy the parts to build this nifty meter , for twice what
it costs new.
Interestingly , the vco ( audio tone ) circuit both generates a tone for the antenna voltage
signal it receives " and " this tone is representative of the signal as received. In other
words, if you receive a 60 hz ac power signal from wall wiring or the case of your
computer , this vco generates a voltage relative of the strength of the signal received
( the stronger the signal the higher pitched the tone ) " and " this tone has the
characteristic 60 hz " rasp or buzz modulation superimposed on the audio output tone
of the vco. The 60 hz ULF signal from wall wiring is below the range of human
hearing , this meter " up converts " the signal ( via the vco ) to an audible signal.
" This " is a critical feature of this meter because it provides many important
advantages .
Of the several inexpensive AC milligauss meters on the market, this is the only one with
that feature. When the vco tone is fed into a spectrum display program such as Spectrogram
or the freeware Spectrum Lab , the software will show " both " the vco oscillator tone
" and " the modulation superimposed on the tone as well. If you are receiving
a 7 hz Schumann wave on the Gauss Master , the Spectrum display program will
display a spectrum line at " both " the 2000 hz ( nominal ) generated audio vco
tone , and a spectral line at 7 hz in the display program .
If you adjust the software to show ( say ) 40 hz or less , then only the ULF 7 hz signal is
displayed and seen. This 7hz ULF signal is quite clearly " heard "( on the speaker )
and " seen " ( on the front panel meter ) by the operator too. ( see the signal
documentation and recording section for more about this )

Operation
:
This
instrument is 9 volt battery
powered and has both a 2
range meter
display and a handy
" audio " tone signal to boot. A press, of the side activation switch, provides the user with
two levels of EMF sensitivity. When pressed in and held , the meter has a range of 0 - 1
AC milligauss and when pressed in and let go, the meter has a range of 1 to 10 AC milligauss.
When pressed, and let go , the Gauss Master operates for several minutes and automatically
shuts off. This feature is intended to be a battery saver . Normal operation with this instrument
is detection and measuring of AC ( man made ) electromagnetic waves. It is VERY sensitive
and easily measures and indicates on DC geomagnetic waves as well, if it is manually moved
through the waves being measured. You can wave it around when holding the activation button
in the sensitive ( low ) range and easily detect the earth's magnetic field. when carried
in your car or bicycle etc.. The Gauss Master is capable of detecting DC magnetic waves if
it is carried through the wave while in motion causing the static magnetic field to " cut " the
antenna / sensor and generate a tone / reading.

Circuitry
:
The
Gauss Master has an inductive
coil antenna which is capacitor
coupled
into an
signal strength meter circuit, and a handy audio VCO. This meter is very handy to use
because the user can make measurements and not have to look at the instrument to
know when signals are measured, and how strong ( relatively ) they are. The handy
VCO ( voltage controlled oscillator ) audio circuit makes a tone when electromagnetic
waves are detected. The stronger the wave, the higher pitched the tone becomes.
The pitch of the tone and the strength level , indicated on the front panel meter, are
directly proportional. The higher the meter reading , the higher pitched the tone , the
stronger the wave detected.

The
Gauss Master , good as it is ,
can be improved upon and can
be used for
many other applications. It provides a handy method of low cost " user interface"
for an array of other , related , applications. The meter and VCO circuitry act as a
type of " up converter " as the AC magnetic waves it usually measures are below the
range of human hearing. When it detects ac waves with it's antenna coil , it changes
these waves into a audible tone and a level meter reading. Capable of detection of DC
magnetic waves if kept in motion in their presence , this meter provides the best of
both ac and dc magnetic wave / signal detection worlds at a very low cost.
