FHC-VALLEYLABFX
FHC Valleylab FX Electrosurgical Generator
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 sinusoidal bursts witha randomized repetition centered at 28 KHZ. Frequencies include 21 KHZ.
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.
WEIGHT AND DIMENSIONS
HEIGHT: 11.1 CM (4 3/8")
WIDTH: 35.6 CM (14")
LENGTH: 43.9 CM (17")
WEIGHT: < 8.1 KG (< 18 LBS)
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 M ARMS
MONOPOLAR: Less than 150 M ARMS
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™ T rip is baseline impedance plus 40%. For example, if the baseline impedance is 30 ohms, the upper level trip is approximately 42 OHMS. If the pad-patient impedance falls below the baseline impedance, a new baseline is established.
