Ultrasound Transducer Leakage Current Tester
Using the ULT800

Using the ULT800

  Warning

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.

 Caution

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 V ac, 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.

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.

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.

light glows amber when the self-test routine completes with a
successful battery test.

Checking Solution Conductivity

Note

The LED indicating a test result remains on for 12 seconds.
The ULT800 then powers off to conserve the battery. To
resume testing, power on the ULT800, allow the self­check/battery test to complete, and then reinitiate the test.

1. Select CONDUCTIVITY.

2. Press the ON/TEST button to perform a measurement
cycle.

3. At the end of the measurement cycle (two seconds), the
LED indicates the results of the test.

The green PASS light illuminates if the solution passed the
Conductivity Test. The red FAIL light illuminates if the solution
failed the Conductivity Test. Check that you have immersed the
electrodes to a depth of at least 25 mm (1 inch) and that they are
firmly connected to the ULT800, then retest. If the failure repeats,
replace the solution and then retest.
