Duty Cycle; Low-Frequency (50/60 Hz) Leakage Current; High-Frequency (Rf) Leakage Current - Covidien ForceTriad Service Manual

Performance Characteristics

Duty Cycle

Under maximum power settings and rated load conditions, the system 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.
Caution
Use of duty cycles greater than 25% (10 seconds active followed by 30 seconds inactive) increases
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.
