9-6 ForceTriad User’s Guide
Duty Cycle
Under maximum power settings and rated load conditions, the ForceTriad energy
platform is capable of operating a duty cycle of 25%, defined as 10 seconds active
and 30 seconds inactive, in any mode for a period of 4 hours.
Low Frequency (50/60 Hz) Leakage Current
Deactivation impedance User selectable: 1,500 Ω, 1,800 Ω, 2,000 Ω or
2,200 Ω
Measurement accuracy ± 14% of Full Scale activation impedance while
keying active above 10 watts
+ 50%, -14% of full scale activation impedance
while keying active at 10 watts or below
± 5% of Full Scale activation impedance while
keying inactive
Keying delay User selectable in 500 msec increments from
0 sec to 2.5 sec
Caution
Use of duty cycles greater than 25% (10 seconds active followed by 30 seconds
inactive) will increase the risk that heat build-up under a return electrode may be
high enough to injure the patient. Do not continuously activate for longer than one
minute.
