1. Safety instructions
The ECG/EMG box is only suitable for educational
purposes. The measurement data and curves
obtained with it must never be used for assessing the
state of health of a person.
• Do not use the ECG/EMG box for diagnostic
purposes.
• Do not use the ECG/EMG box for monitoring the
effects of therapeutic treatments.
• The ECG/EMG box must not be opened or
interfered with under any circumstances.
• Do not operate the ECG/EMG box near heart
pacemakers or other electrical stimulation or
therapeutic devices.
• Only connect the ECG/EMG box to one test
person at any time.
The ECG/EMG box is constructed in accordance with
the current safety requirements for “Protection Class
II, Classification BF (body float)”!
• An instrument configuration consisting of the
ECG/EMG box and the 3B NETlog
TM unit may only
be operated with a PC that conforms to the
current CE regulations!
2. Description
Sensor box for the measurement of an
electrocardiogram (ECG) on the skeletal musculature
using the three standard Einthoven limb leads I, II
and III:
Lead I: from right arm to left arm;
Lead II: from right arm to left leg;
Lead III: from left arm to left leg.
The three leads can be selected by push-button and
the choice is indicated by an LED.
The equipment works by measuring the changes in
skin surface potential caused by contraction of the
heart.
The action potentials of muscles in both relaxed and
energised states can also be measured
(electromyogram, EMG).
The sensor box is detected automatically by the 3B
NETlog
TM unit.
