The ToFscan may temporarily not dis-
play result during transient electro-
magnetic disturbances such as the
use of electrosurgery device. In that
case, the ToFscan will maintain the
safety of the patient and the user.

Stimulations
• TOF (Train Of Four), T4/T1 and T4/Tref calculations.
• AUTO TOF (ToF programmed from 15s to 15min).
• TET (Tetanus 50 Hz)
• DBS (Double Burst Stimulation) modes 3.3 and 3.2
• PTC (Post Tetanic Count)
• ATP (Automatic TOF PTC)
• TWITCH (Single Twitch) 0.1 Hz and 1 Hz.
Acceleration sensor
• Three-dimensional accelerometer (+/- 8 G at 10 bits, Fq:200 Hz, Resolution 0.016G)
Electrical stimulations
• Constant output current of 0 to 60mA (accuracy +/- 10%) (on an resistive load of 4 Kohms)
• Monophasic, duration of impulse 200 µs, frequency 50 Hz
