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: service@fluke.com

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.

Using the ULT800

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.
