Intelect Transport® Combo Therapy System
A. General
The following information is intended to aid in
troubleshooting the major components of the
Intelect Transport Combo Therapy System to
“Board Level” only. These tests are FACTORY
standard testing procedures and methods
used at the factory before shipment of any
Intelect Therapy System.
Due to the complex nature of the technology
utilized by Chattanooga Group, the
recommended troubleshooting techniques
are to determine “Bad Board” and board
replacement only. No board component
level troubleshooting is recommended, nor
will information or parts be supplied by
Chattanooga Group. Any board component
level troubleshooting performed will be at
sole risk and liability of the Service Technician
performing such troubleshooting techniques.
Once a particular PC Board has been
determined as bad, refer to the appropriate
Removal and Replacement Section of this
Manual for proper replacement.
B. Special Tools, Fixtures, & Materials Required
Certain tests require the use of special
tools and fixtures. These will be listed at
the particular test where they are required.
Testing with any other special tool or fixture
other than those stated could give erroneous
readings or test results. Always perform the
tests exactly as stated to ensure accurate
results.
Scope and other standard test equipment
settings will be listed for each test performed
to aid in performing the test to FACTORY
standards and ensure proper readings.
The troubleshooting and repair of the
Intelect Transport Therapy Systems and
Accessories should be performed only by
authorized technicians trained and certified by
Chattanooga Group.
C. Equipment Required
Oscilloscope and Probes
ESTI-2 Load Test Fixture
Digital Multi meter
Intelect Transport Applicators (Accessories)
Dielectric Withstand (Hi-Pot) and ground
resistance tester
NOTE
:
Adjust Dielectric Withstand tester to indicate
fault with 120 k Ohm Load across the output
when at specified test voltage.

Milliohm Meter
10k Resistor
Ohmic Instruments UPM DT 10 or DT
100 Ultrasound Power Meter
Dissolved Oxygen Test Kit used to test
oxygen level of Degassed Water
# 1 Phillips Screwdriver
# 2 Phillips Screwdriver
Insulated Needle Nose Pliers
1/4" Nut driver or Wrench
Degassed Water (<5 ppm) for
Ultrasound Power Meter
Recipe(s) for Degassed Water
1) Boil Distilled Water for 30 Minutes.
Place water in a canning jar, and cover.
Allow to cool to room temperature
of approximately 70 °F (21 °C). May be
refrigerated to aid cooling time.
or
2) Bring Distilled Water to a boil. Place
the container under vacuum for 5 to 10
Minutes.
NOTE:
Canning jars are ideal storage and transport containers
for Degassed Water. In order to minimize aeration
of Degassed Water during transport, fill to a positive
meniscus and slide the lid over the surface. Seal tightly.
When pouring Degassed Water into and out of
containers pour slowly down the side of the container
to minimize aeration.
Do not use Tap Water or Distilled Water in the
Ultrasound Power Meter. Use only Degassed Water in
order to obtain correct test results. The chart below
illustrates the oxygen content of Degassed, Tap, and
Distilled Water.
WATER TYPE
ppm of OXYGEN
Degassed
(per Recipe 1 or 2)
Less than 5 ppm
Tap Water
Up to 35 ppm
Distilled Water
Up to 20 ppm
