The Diagnosis programs P7 and P8

Programs P7 and P8 are provided for the setting of an Intensity/Duration curve
also known as I/t curve (I = Intensity and t = Duration/Pulse width).
The values are ascertained as follows:
»
Attach the electrode to the patient.
»
Connect the device and electrode with the electrode cable.
»
Switch on the stimulator with the
»
Select program 7 or 8 with the
»
The stimulation starts with the pulse width of
1000 ms. The active pulse width in milliseconds
(ms) is always shown in the lower right-hand
corner of the display. Slowly increase the intensity
with the left-hand
movement is perceived. Enter the ascertained
value for the current (I: intensity) and the actual
pulse width (t: duration) in an I/t diagram
(please refer to the enclosed forms).
»
Change to the next pulse width with the right-hand
reset to zero. The previous pulse width can also be re-selected with the left-hand
key.
»
The intensity can again be slowly increased with the
left-hand key (4) until an active muscle movement
is perceptible. Enter the ascertained value for the
current (I: intensity) and pulse width (t: duration)
in an l/t diagram.
»
The value of the I/t curve ends at a pulse width of
10 ms or at the pulse width at which no muscle
movement is detectable. In total, 8 different pulse widths are available.

Switching off the device

Press the key to switch off the device. If the battery level has fallen below a
critical value or outside the stimulation no button has been depressed for a period
of two minutes, the device switches off automatically. An acoustic signal is then
transmitted.
