Vectra Genisys®/Intelect Legend XT®/ Intelect® Vet Therapy Systems
5 TROUBLESHOOTING
A. General
The following information is intended to aid
in troubleshooting the major components
of the Vectra Genisys, Intelect Legend XT
and Intelect Vet Therapy Systems to “Board
Level” only. These tests are FACTORY standard
testing procedures and methods used at
the factory before shipment of any Vectra
Genisys, Intelect Legend XT, or Intelect Vet
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.
Any special tools or fixtures required can
be obtained through Chattanooga Group
Service Department.
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 Vectra
Genisys, Intelect Legend XT or Intelect Vet
Therapy Systems, Modules, and Accessories
should be performed only by authorized
technicians trained and certified by
Chattanooga Group.

Ultrasound 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
Ohmic Instruments UPM DT 10 or DT 100
Ultrasound Power Meter
Audio Signal Generator, B-K Precision, Model
3001
14 cm diameter (5.50”) Optical Cast IR
Longpass Filter (For Cluster Laser
Applicators)
UV and IR Laser Detection Cards (For Laser
Applicators)
Dissolved Oxygen Test Kit. Used to test
oxygen level of degassed water
Degassed Water (<5 ppm) for Ultrasound
Power Meter
D. Recipe(s) for Degassed Water
Boil Distilled Water for 30 minutes. Place
water in a non-porous container and
immediately cover with cellophane.
Allow to cool to room temperature
of approximately 70 °F (21 °C). May be
refrigerated to aid cooling time.
Bring Distilled Water to a boil. Place the
container under vacuum for 5 to 10
minutes.
NOTE:
Two liter soft drink bottles are ideal storage and
transport containers for degassed water as they are
designed to keep oxygen out. Do not allow aeration of
degassed water during transport or filling of the power
meter.
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
