Refractory Period Delay
The three modes: TOF, DB and PTC are subject to refractory period delays, providing a
safety period which prevents the user from repeating stimulation while the nerve synapse
is recovering from the effects of the previous stimulation.
Immediately after stimulation in one of these modes, the countdown timer is activated and
shown on the screen. If repeat mode is activated, only the repeat timer will be displayed
on the screen because the repeat period for the repeat timer will always be larger than the
refractory period timer. If an attempt is made to stimulate while the refractory timer is active
a warning screen will be displayed reminding the user that the refractory period is active.
Default refractory period delays are as follows for the three modes:
TOF: 15 seconds
DB: 1 minute
PTC: 2 minutes
