• Three cut modes, all controlled by Instant Response™ technology, offer surgeons a variety of choices:
  • Low Cut for delicate tissue or laparoscopic cases

  • Blend for cutting with hemostasis
• Four coag modes:
  • Desiccate for low voltage contact coagulation suitable in laparoscopic and delicate tissue work

Output Waveforms

• Bipolar
  • Precise: 470 kHz sinusoid
  • Standard: 470 kHz sinusoid
  • Macro: 470 kHz sinusoid
• Monopolar Cut
  • Low: 390 kHz sinusoid. Similar to the Pure Cut mode except the maximum voltage is limited to a lower value.
  • Pure: 390 kHz sinusoid
  • Blend: 390 kHz bursts of sinusoid, recurring at 27 kHz intervals. 50% duty cycle envelope.
• Monopolar Coag
  • Desiccate: 240 kHz sinusoid repeated at 39 kHz. 8% duty cycle.
  • Fulgurate: 390 kHz damped sinusoid bursts with a repetition frequency of 30 or 57 kHz into 500 ohms.
  • Spray: 390 kHz damped sinusoidal bursts with a randomized repetition centered at 28 kHz. Frequencies include 21 kHzz < f < 35 kHz. Output is further modulated by a random 250 Hz envelope with a variable duty cycle.

Output power changes by less than 15% or 5 watts, whichever is greater, as the line voltage varies from 104-132 volts and 208-264 volts (at rated load).

Low Frequency Leakage (50-60 Hz)
Source current, patient leads, all outputs tied together.

• Normal polarity, intact chassis ground: < 10 µA
• Normal polarity, ground open: < 50 µA
• Reverse polarity, ground open: < 50 µA
• Sink current, 140V applied, all inputs: < 50 µA

PER = 98
PER (Power Efficiency Rating) is the measure of an electrosurgical generator’s ability to accurately deliver the selected power into a wide range of tissue types.

Physical Weight & Dimensions

• Height: 57 inches
• Width: 51-1/2 inches
• Depth: 24-1/8 inches

Input Power Requirements
Operating range is 85 to 132 AC volts. Maximum current is 7 amperes in Cut and 4 amperes in Coag.

High Frequency Leakage

• Bipolar: Less than 60 mA (rms)
• Monopolar: Less than 150 mA (rms)

REM™ Contact Quality Monitoring System

• Measurement Frequency: 80 kHz ± 10 kHz
• Measurement Current: Less than 10 µA
• Acceptable Resistance Ranges:
  • REM™ pad – 5-135 ohms
  • Non-REM™ pad – less than 20 ohms
• Acceptance range is 5-135 ohms after REM PolyHesive II return electrode is applied.
• Adaptive REM™: REM™ trip is baseline impedance plus 40%. For example, if the baseline impedance is 30 ohms, the upper level trip approximately 42 ohms. If the pad-patient impedance falls below the baseline impedance, a new baseline is established.
