FHC-VALLEYLABEZ
FHC Valleylab EZ Electrosurgical Generator
OUTPUT WAVE FORMS:
BIPOLAR: 470 KHZ sinusoid
MONOPOLAR CUT:
PURE: 393 KHZ sinusoid
BLEND: 393 KHZ bursts of sinusoid, recurring at 27 KHZ intervals.
50% duty cycle envelope
MONOPOLAR COAG:
DESICCATION:
LOW 1: 240± 40 KHZ sinusoid recurring at 39 KHZ 8% duty cycle
LOW 2: 393 KHZ sinusoid
LOW 3: 393 KHZ sinusoid
FULGURATION:
HIGH 1: 470 ± 40 KHZ damped sinusoidal bursts with repetition
frequency of 57 KHZ
HIGH 2: 470 ± 40 KHZ damped sinusoidal bursts with repetition
frequency of 30 KHZ
Output power changes by less than 15% or 5 watts, whichever is
greater, as the line voltage varies from 90-135 volts and 186-264
volts (into a 300 OHM 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
POWER READOUTS
Agree with actual power into rated load to within ± 15% or 5 watts, whichever is greater. Dosage error monitor.
PER = 97
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: 12.7 CM (5")
WIDTH: 40.6 CM (16")
LENGTH: 39.5 CM (15.6")
WEIGHT: < 6.8 KG (< 15 LBS)
INPUT POWER REQUIREMENTS
110-120 VAC 220-240 VAC
Operating Range 58-140 VAC 170-280 VAC
Max Current Cut 8A 4A
Max Current Coag 4.2A 2.1A
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.
