Warranty and Product Support
Fluke Biomedical warrants this instrument against defects in materials and
workmanship for one full year from the date of original purchase. During the
warranty period, we will repair or, at our option, replace at no charge a prod-
uct that proves to be defective, provided you return the product, shipping
prepaid, to Fluke Biomedical. This warranty does not apply if the product has
been damaged by accident or misuse or as the result of service or modification
by other than Fluke Biomedical. IN NO EVENT SHALL FLUKE BIO-
MEDICAL BE LIABLE FOR CONSEQUENTIAL DAMAGES.
Only serialized products and their accessory items (those products and items
bearing a distinct serial number tag) are covered under this one–year warranty.
PHYSICAL DAMAGE CAUSED BY MISUSE OR PHYSICAL ABUSE IS
NOT COVERED UNDER THE WARRANTY. Items such as cables and
nonserialized modules are not covered under this warranty.
Recalibration of instruments is not covered under the warranty.
This warranty gives you specific legal rights, and you may also have other
rights which vary from state to state, province to province, or country to
country. This warranty is limited to repairing the instrument to Fluke Bio-
medical’s specifications.
Warranty Disclaimer
Should you elect to have your instrument serviced and/or calibrated by some-
one other than Fluke Biomedical, please be advised that the original warranty
covering your product becomes void when the tamper-resistant Quality Seal is
removed or broken without proper factory authorization. We strongly rec-
ommend, therefore, that you send your instrument to Fluke Biomedical for
factory service and calibration, especially during the original warranty period.
In all cases, breaking the tamper-resistant Quality Seal should be avoided at all
cost, as this seal is the key to your original instrument warranty. In the event
that the seal must be broken to gain internal access to the instrument, you
must first contact Fluke Biomedical’s Technical Assistance Department at
775-883-3400. You will be required to provide the serial number for your in-
strument as well as a valid reason for breaking the Quality Seal. You should
break this seal only after you have received factory authorization. Do not
break the Quality Seal before you have contacted us. Following these steps
will help ensure that you will retain the original warranty on your instrument
without interruption.

Introduction
The ULT800 TEE Transducer Leakage Current Tester measures the
leakage current of ultrasound transducers independent of their ultrasound
systems. Use the hand-held, battery-operated instrument during the routine
transducer cleaning procedure conducted between patients.
Connect the transducer to be tested to the ULT800 via a unique adapter.
The ULT800 performs the measurement with the transducer immersed in
either the cleaning solution or saline. To insure that the leakage current
test is accurate, first test the conductivity of the fluid. A special dual
element probe also connected to the ULT800 tests the conductivity of the
fluid. A green PASS light or a red FAIL light indicates the results of the
conductivity and leakage current tests.
In addition to verifying that the ultrasound transducers are safe for patient
use, the ULT800 makes it possible to reduce expensive repairs. Identifying
transducers that exceed safe leakage currents early may allow for repairs
to be made before a transducer becomes non-repairable.
Key Features
•Hand-held instrument
•Stand-alone operation
•Direct measurement of leakage current
•Battery operation for safety
•Independent of 120 or 240V ac systems
•Built-in self-test circuit
•Auto shut off to conserve battery

Claims
Our routine method of shipment is via common carrier, FOB origin. Upon
delivery, if physical damage is found, retain all packing materials in their
original condition and contact the carrier immediately to file a claim.
If the instrument is delivered in good physical condition but does not operate
within specifications, or if there are any other problems not caused by shipping
damage, please contact Fluke Biomedical or your local sales representative.
Certification
This instrument was thoroughly tested and inspected. It was found to meet
Fluke Biomedical’s manufacturing specifications when it was shipped from the
factory. Calibration measurements are traceable to the National Institute of
Standards and Technology (NIST). Devices for which there are no NIST
calibration standards are measured against in-house performance standards
using accepted test procedures.

Obtaining Assistance
If you have trouble operating the equipment, or just need some clarification on
its operation, contact Fluke Biomedical’s Technical Assistance Center at 800-
648-7952.
Returning the Instrument to Fluke
If it becomes necessary to return your instrument to Fluke, proceed as follows:
1. Every product returned to Fluke must have a Return Material
Authorization (RMA) number. To obtain an RMA, contact Fluke
through one of the following methods:
Phone: 888-99FLUKE (888-993-5853) or 425-446-5560
Email: [e-mail]
2. Pack the instrument carefully, using the original packing materials if
available. Failure to pack the instrument properly could void your
warranty and result in you paying for the instrument’s repair.
Insure the unit for full retail value and ship to the address specified by Fluke.

READY Glows amber when the self-test procedure
completes (approx. 8 sec.). The ULT800 is
then ready for testing.
PASS Glows green when either the Conductivity
Test or Leakage Test passes.
FAIL Glows red when either the Conductivity Test
or the Leakage Test fails. Pulses red when
the Leakage Test results in less than 20 µA,
indicating a possible open circuit condition
with invalid test results.
LOW BAT Flashes red to indicate that the battery
requires replacement.

XWWarning
To avoid personal injury, do not touch the dual
conductivity electrode rods. Voltage is present on the rods
during a test.
Inspect the conductivity probe for damaged insulation or
exposed metal. To avoid personal injury, replace a
damaged conductivity probe before using.
WCaution
To avoid damage to the transducer, observe the immersion
levels. Do not immerse or allow the cable or connector of a
transducer to become wet.
The ULT800 TEE Transducer Leakage Current Tester is a portable, self-
contained, battery-operated device. It measures the leakage current of the
devices attached to its connectors. The ULT800 applies 120 VAC, 60 Hz
to devices placed in a conductive bath (basin or storage tube). The
ULT800 measures the current and compares the results to an internal
threshold. The instrument displays the results as a PASS or FAIL
indication. It also performs an internal self-calibration on each
measurement cycle.
The ULT800 makes two types of measurements. The Leakage Test
measures the current between the probe and the electrode. The
Conductivity Test measures the conductivity of the bath solution between
the two electrodes.
Figures 2 and 3 show some typical test setups. Figure 2 shows the
HP/Agilent Disinfection Basin (HP Part No. 21110A). Figure 3 shows the
ATL Disinfection and Storage Tube. You can use other setups, as long as
you observe the following rules:
1. Connect the ultrasound probe you are testing to the probe
adapter. See the list of available adapters under Accessories.
2. Place the probe you are testing in a saline bath with the entire
critical area of the probe fully immersed.
3. Place the dual electrode (Part No. 2392502 or 2392569) in the
saline bath to a depth of at least one inch.
