Selecting the Pulse Width
Setting a Pulse Width sets the duration of the stimulation pulse.
In the
Setup NMT window:
1 Click on Pulse Width to open the Pulse Width window.
2 Select the required setting.
3 Select Confirm if you wish to modify a previously calibrated pulse width.
CAUTION
Changing the stimulation pulse after calibration invalidates the stored reference data.
Value Lifetime
Displays the time after which an NMT numeric value disappears from the resting display.
The
Value Lifetime setting is visible (grayed out) in the Setup NMT window. The setting can only be
changed in the Configuration Mode.
NMT Tone Volume
Enters a list of selections to adjust the audio volume of the NMT stimulation tone. If not zero, each
NMT stimulation pulse is indicated by a short beep.
You can change the
NMT Tone Volume in the Setup NMT window.

In the Setup NMT window:
1 Select the TOFcnt High Lim.
2 Select limit: 0, 1, 2, 3.
NMT Alarm Suppress
Depending upon your configuration, the TOFcnt high alarm maybe suppressed until the TOFcnt value
has reached 0 for the first time. This setting can only be changed in the Configuration Mode.
Understanding NMT Numerics
Numerics
TOF ratio (TOFrat), TOF count (TOFcnt), Twitch ratio (Twitch) and DBS Count (DBScnt) numerics
show the result of an NMT measurement. Together with these numerics either the time the
measurement was taken or the time until the next measurement is shown. The extended numeric
representation shown will only be available when using a screen designed to show it. The relative
strength of individual muscle responses, as measured by the acceleration sensor are displayed as a bar
graph.
