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.
