Mode of Operation of the Treatment
The BCR Premium MSTU 100 is a treatment system of the category of “electrotherapy
devices“ and “LED light therapy devices“ and is used for Preventive Health/Wellness,
Rehabilitation of pain/physical disabilities and Beauty.
In the biological therapy through microcurrent, currents between 10 and 999 microamps [µA],
with frequencies between 0.1 and 10,000 Hertz [Hz] are applied to the affected region using
electrodes. With this low current, a stimulation of physical activity takes place, which is the
basis of the healing process.
Verifiably, microcurrent is effective in the painless therapy of acute and chronic pain,
especially of the joints. Studies show a reduction in pain through microcurrent e.g. in cases
of Arthrosis, Arthralgia, Epicondylitis (tennis elbow), Fibromyalgia, etc.
A blood circulation promoting effect has also been proven, which is beneficial for the
rehabilitation of physical disabilities and wound healing.
BCR Premium MTSU 100 is controlled by a central microprocessor. All user in- and outputs
are performed via a capacitive touch display. The hardware for the generation of the
microcurrents allows for the independent generation of current pulses with frequencies of up
to 1 kHz for two channels, with currents up to 999 µA.
Additionally, a constant measurement of the skin resistance takes place. The generation of
an initial voltage of 60V for each channel is galvanically isolated from all other electric
potential, and allows for both the simultaneous treatment of one area or region with different
currents, or the independent treatment of different regions.
Through the use of a flash-processor, the installation of firmware updates by the user is
possible at any time.
The following parameters can be set for the channels:
•Currents from 10 to 999 µA in 1 µA steps
•Pulse frequencies of 0,1 Hz to 1 kHz in 0,1 Hz steps
•Rise time of the preset current from 0,1 to 1,0 sec (Amplitude modulation of the current
output from 10 to 100% within the selected time in 10% steps)
From the output of current-controlled impulses, the maximum strength of which can be
selected, the amplitude of the voltage output is derived, depending on the connected load,
the body through which the current flows. The maximum Amplitude of the voltage is limited to
60 Volts, so that the following relationship is valid for maximum current output (Ohm’s law):
R = U / I
Rx = 60V / 990µA
Rx = 60.6 kΩ

Änderungen vorbehalten – Stand 08.05.2019

This means that in cases where the resistance of the connected body is lower than 60 kΩ,
linearly lower voltages can be expected. Current regulation provides for an absolute short
circuit resistance, and thereby the safety of the system.
The period of a master unit for current output is 2.5 seconds, so that the channels are
restarted after 2.5 seconds while a program is running. The purpose of this sequence is as
follows:
•A change, respectively restart every 2.5 seconds
•Channel A and/or B can output current impulses unidirectional (+ or -) or bidirectional,
meaning that the polarity changes from + to – and vice versa after 2.5 seconds.
Simultaneously with the start of a cycle, the rise of the current is reactivated, so that an
amplitude-modulated current flow follows.
Here is an example of a measured output signal:
The voltage was measured on a load of 10 kΩwith the following parameters:
Polarity: +/- , Current: 500µA , Rise time: 1 sec , Frequency: 3 Hz
At the beginning of a period, the amplitude of the pulses is zero, then it rises to its maximum
value of 5 Volts within 1 second. It maintains this amplitude until the end of the period.
(U=R x I, so 10kΩx 500µA = 5V)

The device contains an automatic diagnosis mode. At the start of each program segment,
the conductivity of the connected body is measured on channel A, and the value is scaled on
a logarithmic scale from 0 to 100. A value of 50 on this scale corresponds to a resistance of
95 kΩ. This is based on Dr Voll’s theory where the values 0 to 100 equates to 0 to 800 kΩ
resistance over the organ or tissue where 95 kΩ, the baseline value of balanced energy,
equals to 50 in the scale.

this manual for more detailed information.
