Group International, Inc. recommends that it be
calibrated at least once every 12 months.
Calibration must be done by qualified personnel.
Contact BC Group International, Inc. for
calibration.
ii
WARNING - USERS
The ESU-2000A is for use by skilled technical
personnel only.
WARNING - USE
The ESU-2000A is intended for testing only and
should never be used in diagnostics, treatment or
any other capacity where it could come in contact
with a patient.
WARNING - CONNECTIONS
All connections to patients must be removed
before connecting the DUT to the ESU-2000A. A
serious hazard may occur if the patient is
connected when testing with the ESU-2000A. Do
not connect any leads from the patient directly to
the ESU-2000A or DUT.
WARNING - MODIFICATIONS
The ESU-2000A is intended for use within the
published specifications. Any application beyond
these specifications or any unauthorized user
modifications may result in hazards or improper
operation.
WARNING - USE
Never touch exposed metal surfaces on test leads
or other current-carrying parts while the DUT is
activated.
iii
WARNING - LIQUIDS
Do not submerge or spill liquids on the ESU-
2000A. Do not operate the ESU-2000A if internal
components not intended for use with fluids may
have been exposed to fluid, as the internal leakage
may have caused corrosion and be a potential
hazard.
CAUTION - SERVICE
The ESU-2000A is intended to be serviced only by
authorized service personnel. Troubleshooting
and service procedures should only be performed
by qualified technical personnel. Never open the
ESU-2000A while connected to the DUT, as a
hazardous condition may exist.
CAUTION - ENVIRONMENT
Exposure to environmental conditions outside the
specifications can adversely affect the
performance of the ESU-2000A. Allow ESU-2000A
to acclimate to specified conditions for at least 30
minutes before attempting to operate it.
CAUTION - INSPECTION
The ESU-2000A should be inspected before each
use for wear and should be serviced if any parts
are in question.
CAUTION - VENTILATION
The ESU-2000A includes ventilation slots to help
prevent overheating during operation and should
not be blocked.
CAUTION - FUSE
Only replacethe ESU-2000Afuse with the specified
type and rating.
iv
CAUTION - CLEANING
Do not immerse. The ESU-2000A should be
cleaned by wiping gently with a damp, lint-free
cloth. A mild detergent can be used if desired.

The Model ESU-2000A is a precision Electro-Surgery Unit Analyzer (ESU). It tests the RF
power output of Electro-Surgery Units. The power reading is taken from a large 4-½ inch
analog display. It offers sixresistive loads forRF power testing from50 to500ohms,along
with a 200 ohm load forRF leakage current testing. The patientreturnelectroderesistance
simulation is adjustable in one ohm increments from 0 to 999 ohms.
The following are highlights of some of the main features:
•LARGE 4 ½ INCH ANALOG DISPLAY
•± 2% OF FULL SCALE CURRENT ACCURACY
•0-10 MHz BANDWIDTH
•RETURN CONTACT MONITOR TEST
•RF LEAKAGE TEST
•ISOLATED OSCILLOSCOPE OUTPUT
•PORTABLE
•EASY OPERATION
•NO BATTERIES OR POWER SUPPLY REQUIRED
•STANDARD ACCESSORY KIT INCLUDED
•HIGH IMPACT PLASTIC ENCLOSURE

DUT RF Power Measurements
1. Consult the DUT manufacturer’s manual for load specifications.
2. Remove all connections between the DUT and the ESU-2000A Analyzer.
3. Install the 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 a single electrode REM cable from the ESU-2000A terminal labeled
“Patient Plate” to the DUT’s Patient Plate or Return Electrode.
5. Connect a yellow safety lead from the DUT’s RF Active Output to the desired load
terminal of the ESU-2000A. The Active Electrode input connectors are color coded,
and each corresponds to a color-coded range on the analog meter.
6. Set the DUT for proper output mode and power level, being careful that the power
setting does not exceed the full-scale Power range selected on the ESU-2000A.
7. Activate the DUT output. The Analyzer will indicate both mA RMS and Power (W)
on the appropriate color-coded wattage meter range.
8. Deactivate the DUT outputbeforedisconnectingfromESU-2000A,orbeforemoving
the Active Electrode test lead to a different input range connector.
DUT RF Leakage Current Measurements
1. Remove all connections between the DUT and the ESU-2000A Analyzer.
2. Install the 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 ayellow safety lead from the ESU-2000A terminal labeled “RF Leakage” to
the DUT’s RF ActiveOutput.DONOTMEASUREACTIVEELECTRODELEAKAGE
ON NON-ISOLATED ESUs with the ESU-2000A. Damage may occur to the ESU-
2000A.

4. Connect a green safety test lead from the ESU-2000A terminal labeled “EARTH” to
the DUT’s Earth Ground; an alligator clip with safety jack may be necessary. If no
accessible Earth Ground point exists on the DUT, it is acceptable in most cases to
use Receptacle Earth.
5. Set the DUT for proper output mode and power level.
6. Activate the DUT output. The Analyzer will indicate the RF Leakage current from
the DUT Active Electrode on the color-colored RF Leakage scale.
7. Deactivate the DUT output.
8. Repeat Active Output RF Leakage Testing for all available Output Modes and
Output Electrodes as called for in the DUT Leakage Test Procedures.
9. Remove the yellow safety lead from the DUT’s RF Active Output and the ESU-
2000A.
10. Connect the single electrode REM cable to the DUT’s Patient Plate or Return
Electrode and the Leakage Input on the ESU-2000A.
11. Set the DUT for proper output mode and power level.
12. Activate the DUT output. The Analyzer will indicate the RF Leakage current from
the DUT Active Electrode on the color-colored RF Leakage scale.
13. Deactivate the DUT output.
14. Repeat Return Output RF Leakage Testing for all available Output Modes and
Output Electrodes as called for in the DUT Leakage Test Procedures.
DUT Patient Plate or Return Electrode Monitor Test
1. Remove all connections between the DUT and the ESU-2000A Analyzer.
2. Connect the dual electrode REM cable from the ESU-2000A terminals labeled
“PATIENT PLATE” to the DUT Patient Plate or Return Electrode.
3. Adjust ESU-2000A Patient Plate Resistance as necessary to verify DUT Patient
Plate or Return Electrode Monitor mode as specified by the DUT manufacturer.
