4.3.3
0.1 Hz stimulation button
Starts repetitive 0.1 Hz stimulation.
The third secondary function is the 0.1 Hz stimulation. The display shows the
twitch height of the last response. However, this is only valid when the TOF-Watch
has been calibrated. If not, the
reference control twitch value is used for the calculation.
4.3.4
µs button
Change of stimulation pulse width.
The µs function is used to toggle stimulation pulse width between 200 and 300 µs
for neuromuscular monitoring.
300 µs pulse width can be used if 200 µs at 60 mA is not sufficient to produce
supra-maximal stimulation.
Changing the pulse width invalidates any previous calibration of the TOF-Watch .
Changing pulse width does not affect default setting selected in set-up menu
(see Set-up menu on page 16).
4.3.5
Sensitivity button
Sensitivity of acceleration transducer.
Acceleration transducer sensitivity will be displayed for 5 s after selection of this
button. Sensitivity can be increased/decreased by pressing mA (µC) up (21) or
down (23) during display of the sensitivity.
This function can be used to optimize twitch height percentage manually.
Sensitivity can be adjusted between 1 and 512, where 512 represents the most
sensitive setting. Sensitivity setting 157 is the default sensitivity.
Changing sensitivity invalidates any previous calibration of the TOF-Watch.
