User Manual AlgiScan 23
Caution:
Electrical stimulation can cause muscle contraction and thus an involuntary
movement. The practitioner will take care that this movement does not cause injury to the
patient or bring him/her into contact with other objects or devices.
Connection of the electrode wire from the AlgiScan to the electrodes
Before touching the electrodes, always make sure that the AlgiScan is not in a
stimulation phase.
First, connect the electrode cable to the AlgiScan by pushing in the end of the cable equipped
with the connector in.
The proximal electrode should be connected to the red clip. The distal electrode should be
connected to the black clip.

Note:
The user can disconnect the electrode wire from the AlgiScan at any time to stop
a stimulation or for any other operation that is necessary. The connector is fitted with a
quick-release ring enabling the wire to be disconnected from the AlgiScan by simply pulling
the ring.
Patient/Electrodes conduction level and skin resistance
The level of conduction of the electrodes is checked by the AlgiScan as soon as an electrical
stimulation with a non-zero current is selected. This control is carried out continuously until the
main button is pressed by the user to start the measurement.
The skin resistance is one of the components of the total resistance in the
stimulation circuit, which also includes the resistance of the electrodes. The AlgiScan
generates constant current stimulations. This means that the stimulation voltage
increases automatically according to the resistance. The voltage is limited to a maximum
value of 300 V. For a current fixed at 60 mA; the maximum acceptable resistance is 5 k Ohms.
If the skin resistance is adequate, the AlgiScan displays the electrode symbol in
green. Thus the value of the stimulation applied to the patient will correspond to the value
selected. If the skin resistance value is high, the AlgiScan displays the electrode symbol in
yellow which signifies that the electrical stimulation applied to the patient will be less than the
electrical stimulation selected.
If the resistance is much too high or if the circuit is open (electrode cable is damaged,
electrode not connected to the patient), the AlgiScan displays the electrode symbol in red.
