4. UTION Electro Surgery Units ESUs produce high frequency RF output voltages up to 500 volts CAUTION Always turn the ESU under test Off before making or removing connections CAUTION Never touch exposed metal surfaces on test leads or other current carrying parts while the ESU is activated CAUTION Refer to ESU manufacturer s manuals and specifications for safety and testing information CAUTION Only replace the ESU 2000A fuse with the specified rating and type CAUTION Never open the ESU 2000A case when it is connected to an ESU OPERATING INSTRUCTIONS ESU RF Power Measurements 1 Consult the ESU manufacturer s manual for load specifications 2 Turn off ESU under test Remove all connections between the ESU under test and the ESU 2000A 3 Install the BC Biomedical Switching Module on the ESU 2000A front panel so that the words ESU Power Testing are right side up When installed correctly the Active Electrode connectors should be exposed and the RF Leakage connectors should be inaccessible 4 Connect the ESU s Patient Plate to the ESU 2000A s black Patient Plate connector using a black test lead 5 Connect the ESU s Active Electrode to the ESU 2000A s desired load range connector in the Active Electrode area on the left side of the front panel The Active Electrode input connectors are color coded and each corresponds to a color coded range on the analog meter The full scale watts ran
5. ge for each range equals the input resistance For example the 50 ohms input resistance range has a full scale watts range of 50 watts etc 6 Turn the controls on the ESU under test to minimum power and then activate the CUT or COAG modes Turn the ESU power to the desired levels being careful to not exceed the full scale wattage range selected on the ESU 2000A Note the reading on the ESU 2000A on the proper color coded wattage range and record it if desired If the milliamp output rather than watts is required that reading may be obtained by reading the lower 0 1000 milliamp scale 7 Turn the ESU power to minimum and deactivate the output before disconnecting from ESU 2000A or before moving the Active Electrode test lead to a different input range connector ESU RF Leakage Current Measurements 1 Turn off ESU under test Remove all connections between the ESU under test and the ESU 2000A 2 Install the BC Biomedical Switching Module on the ESU 2000A front panel so that the words RF Leakage Testing are right side up When installed correctly the Active Electrode connectors should be inaccessible and the RF Leakage connectors should be exposed 3 Connect the ESU s Active Electrode to the ESU 2000A s red RF Leakage connector using a red test lead DO NOT MEASURE ACTIVE ELECTRODE LEAKAGE ON NON ISOLATED ESUs with the ESU 2000A Damage may occur to the ESU 2000A 4 Connect the ESU s case ground to the ESU 2000A s
