⍀
No resistance in patient circuit-threshold value monitoring: single sound
pulses are emitted at all times.
1
10 k
⍀
If a resistance greater than 10 k
⍀
is measured in the patient circuit, then a
double sound pulse is emitted.
2
15 k
⍀
If the measured resistance in the patient circuit is greater than 15 k
⍀
, then
a double sound pulse is emitted.
3
20 k
⍀
If the measured resistance in the patient circuit is greater than 20 k
⍀
, then
a double sound pulse is emitted.
4
25 k
⍀
If the measured resistance in the patient circuit is greater than 25 k
⍀
, then
a double sound pulse is emitted.
5
30 k
⍀
If the measured resistance in the patient circuit is greater than 30 k
⍀
, then
a double sound pulse is emitted.
The double sound pulse is not emitted if the nominal current is not reached because, for example, the
resistance in the patient circuit is far too high. This case is signalized with a single sound pulse with a
deeper frequency, indicating the error.
5.1.5 SETUP LEVEL 5: Activation of the Choquet table KAN mode
ATTENTION: This setup level does not have any effect on the catheter mode
.
Pressing the SETUP-button briefl y fi ve times will activate a program option which allows you to adjust
the pulse width for the cannula mode. Here, the pulse width selection mode can be selected by means
of the turnable key button. You can either choose manual selection (Selection 0) or automatic selection
of the pulse width according to the Choquet table (Selection 1).
In the manual mode, the pulse width can be defi ned by the user. In the automatic mode, the pulse
width is dependent on the pulse current and can not be selected and changed directly.

The KAN pulse width is determined automatically, depending on the KAN
pulse current.
5.1.5.1 MultiStim SWITCH Feugeaus/Choquet
Big distance nervous location
MULTISTIM SWITCH has a particular function allowing big distance nervous location. The rotation of
the cursor habitually used to make vary issued intensity involve not only modifi cations of issued inten-
sity, but also of stimulus duration. For the fi nal positioning of the needle near the nerves, it is important
to keep a stimulus duration at 0,1ms value which is validated by scientifi c data and by the common
practice. On the contrary, during the initial detection of nerves, it is desirable to have a maximum of
range of detection got with big stimulus durations (0,3 or 0,5 or 1ms).
