SETUP

The device has been provided with a SETUP-function. This function  
permits the user himself to determine his individual initial parameters  
for the percutaneous and invasive applications. 

Adjustable stimulation pulse width 

The stimulation pulse width can be adjusted fast and simple with a button of 
its own in a number of steps – with intervals ranging from 0.05 ms, 0.1 ms, 
0.2 ms, 0.3 ms, 0.5 ms to 1.0 ms, e.g. for the selective stimulation of sensory 
and motor nerve fibres in mixed nerves. 

Easy to view – simple in application

The MultiStim SENSOR

PEG- and Cannula button*

Pressing the PEG- or Cannula button will cause the stimulation to be 
switched to the handle or to the cannula, as may be required. 
The respectively active electrode will thereby be indicated by means of a 
corresponding status indicator in the display. The intensity and the 
frequency of the stimulation current, as well as the pulse width can be 
adjusted separately for both outputs. This button will remain without 
function if no PEG-handle has been connected. 

* only if the optional PEG-cable and electrode are used

Nominal/actual stimulation current intensity

The intensity of the stimulation current actually flowing through the patient 
is measured constantly, and is indicated numerically as well as by bar graph 
indicator on the display. The nominal and actual currents are also constantly 
compared and indicated visually or acoustically, if the intensity of the 
actually flowing current differs from the adjusted current intensity.

ON/OFF
PAUSE

The stimulation can be interrupted at any time with the PAUSE - button. 
The settings of all stimulation parameters can be changed without emitting 
impulses, while the device remains attached to the patient.
