  Why a Constant Current Source? (Very technical stuff)
(Extract from our main manual)

A zapper kills parasites because of the action of its battery (Direct Current), making possible to a
direct flow of current to run into our body.

No matter the voltage applied, you will need a MINIMUM of CURRENT at destination, and no much more,
for obvious safety reasons : We want to kill pathogens IN VIVO (You, staying alive (:-)

For these same reasons, even a simple 9V battery can be lethal if this very low voltage is applied directly
across the hearth, without any current limiting device (called a RESISTOR).

Ohms Law I=V/R explain the mathematical part of this fact.

This is why the original zapper had a 1000_Ohms resistor to limit maximum current in a safe,
simple and inexpensive way.

Our design problem with zappers, is that most electronic circuits, including the popular 555
oscillator, work with VOLTAGE, current being only a Ohms Law “side effect”.

Because the skin is a wonderful protector against many external aggressions, including Direct Current, a
zapper uses a “high frequency” to overpass this protection, and a square wave to build harmonics, who
are higher frequencies passing even better the skin barrier.

Many manufacturers place a High Pass Filter on the output resistor, to permit to high frequencies to
better pass through the output stage. 
Simple, precise words not selling very well, buzzwords like “expensive super stabilized waves”, “constant
waves” and other definitions had been attributed to this simple circuit.

One of the consequences of this High Pass Filter has been to decrease the original output
impedance to almost 0, leaving the zapper without any safety, current wise.

To resume:
1_  Controlling current is the obvious way to make a zapper work well, as intended

2_  Most electronic circuits are available with voltage control only.

3_  To make a safe, efficient zapper, we need to introduce into the output stage a very fast
(harmonics) current control circuit.

4_  This Current Control Circuit has an electronic name : A constant Current Source

The main problem with this “Fast Reacting, Constant Current Source” circuit, is that it is more
difficult/expensive to implement that the 555 zapper itself.

Because at Maestro-Zapper we want to make good, safe, efficient, state of the art zappers, we
have designed this circuit for our MZ3c.

Even more : Many of our customers have requested an adjustable output for their zapper, finding “super
powerful zappers” with voltages in excess of 12V, uncomfortable to use, specially with sensitive skins.

The designed Adjustable Constant Current Source has many interesting characteristics :
1_  Adjustable from a low 1.5mA to a powerful 7mA.  Original zapper had a peak current of around
3.5mA.  Some zappers are still efficient with 1.5mA.  No need to go to up the 7mA limit to have good
results.  Like a car, being able to go up to 180km/h doesn’t means we have to go at this high speed all
the time!!

For most uses, 1.5 to 3mA will be enough.

2_  High speed reaction well under one microsecond (0.000 001s) permits to this circuit to work
without any scary High pass filter of any kind, and gives sharp square waves, rich in harmonics.

3_  This very fast reaction time permits a strong, firm, safe control of current no matter how the
load (you) could react.

This last point, never mentioned, is a real nightmare when you start trying to resolve-it.

Most zappers have no control, for a very good reason :

How your body will react to a voltage source?  :  In many different ways, depending on:
=  Tiredness, health, age of the person;
=  From the relative humidity of the skin at points of contact;
=  The quality of the skin;
=  From the contact area;
=  From the voltage applied between the contact points.
=  And of utmost importance to us: From the frequency used.

Controlling the current as we do makes this last point an obsolete problem :  Current value sticks
to your need, adjusted by you.  If your body varies its impedance, the VCCS will adjust itself and
continue to give the requested current, by design.

  MZ3c zapper - micro controller inside!! 

This new version of MZ3 integrates several devices into one, convenient package, all following by the
book, the latest recommendations of Dr. Clark:

= SA1 = A zapper with the initial sequence made famous by Dr Clark herself :
7mn to 30kHz, followed by a pause of 20 minutes, repeated 3 times.
Auto stop power at the end of the session (1h01mn).

= SA2 = A zapper using a narrow sweep using 64 different frequencies, between 2426Hz and
2522Hz. To take full advantage of this sweep, Maestro-Zapper has designed an automatic session
(almost) copied from the original sequence: The 7mn (at 30kHz) has been replaced by 28 minutes (at
2.5kHz).  4 times more zapping (28mn instead of 7mn), and only two times longer! (2h: 04mn) 
Ideal when 7-20 is not enough

= SA3 = Coming from our previous experience, we are pleased to add "for free", on this version,
a very particular sequence, using Very Low Frequencies (VLF) whispering to the brain, and
driving to a natural, Deep Sleep experience.
We hope you will appreciate the additional well-being provided by your zapper MZ3c.

=  Cxx = Continuous zapping for 3h09mn, allowing a simple and fast zapping, and a wide range of
experiences, with 6 frequencies easily selected and / or changed, on the fly, at your fingertips. These
frequencies include:
    = CA1 =  The classic 30kHz frequency, the preferred one of Dr. Clark
    = CA2 =  A   L A R G E  sweep, between 8kHz and 16kHz (one octave), leaving 255 different
frequencies!  We don't aim at a particular parasite : We "want them” all!
    = CA3 =  The classic 2.5kHz, enhanced by a narrow sweep, leaving 64 different frequencies.  
The 2.5kHz at its best!!

    = CB1 = 1.0kHz : The best frequency for a zappicator, according to Dr. Clark.
    = CB2 = The popular 15Hz.
    = CB3 = The last, but not the least, for the first time in the field of zappers, the famous frequency of
Schumann:  7.83Hz. This frequency is supported by a carrier of 10kHz and a isochronous modulation, for
an effective zapping experience, 7.83Hz alone could not achieve.

Compare with any other zapper on the market:
You will not find any equivalent, regardless of price ...

Functions available:
= Beeper
= Constant indicator of output current (well connected output)
= Indicator of battery voltage, at the start of the session
= Simple and direct choice of six frequencies
= Choice of four sequences:
     S1 = 7-20 at 30kHz,
     S2 = 28-20 at 2.5kHz,
     S3 = 10.5Hz to 1.5Hz, to relax and sleep deeply ...
     Cxx = Non-stop_3h

= SELECTION OF 4 OUTPUT CURRENTS: 1.5mA == 3.0mA == 5.0mA == 7.0mA

All frequencies have an extended duty cycle, for maximum production of harmonic frequencies.

The MZ3c is ready, as a zapper, to be used for:
    =  General zapping (original sequence 7-20)
    =  Continuous zapping (3 hours max)
    =  Zapping using frequency effect (large sweep, 2.5kHz, 1kHz, 15Hz, 7.83 Hz)
    =  Plate zapping (8.9V minimum and 30kHz)
    =  Homeography (9V minimum and 30kHz)
    =  As a zappicator (1.0kHz)
Beware:  External accessories for plate zapping, homeography or zappicator are not provided.

It has all the features needed for the health professional, as well as the discriminating zapper's

Its voltage and current regulators gives a powerful and reliable zapping, from beginning to end of the

Its selectable output current is suitable for all, sensitive skin, normal skin or “tough guy”.

Four sequences fully automatic with stop at end of session, make it useful in all circumstances.
