CHATTANOOGA
GROUP INC.
No Ultrasound Output
First, check that the duty cycle or intensity is not so low that you can’t observe
water movement on the applicator head. If there is some movement, but not as
high as expected, use an ultrasound power meter to test the output. If it is low,
then follow the Applicator Calibration Procedure in this manual.
If there is absolutely no output, try another applicator. Any Chattanooga Group
applicator from an Intelect
®
Legend or CPS unit that has the same connector will
work.
Did swapping the applicator fix the problem?
Yes
- The applicator is bad.
No
- The generator board is probably bad. Also check the connector and
harness inside the unit.
If you do not have another applicator, you can check for output on the Ultrasound
Generator Board using an oscilloscope. Refer to the Ultrasound Generator Board
drawing and signal list in this manual. If there is output at the board connector,
the applicator is bad.
No Stim Output
Does the display change when a treatment is selected?
No
- The Stim Board is probably bad. Also check the connector and
harness inside the unit.
Yes
- First be sure the leads and electrodes are good. If possible test the
output with a resistor.
Next be sure the output type is available at the channel you are
monitoring. For example, HiVolt is only available from channel 2. See the
manual.
Also check the output harnesses and connectors or monitor the output at
the connector on the Stim Board.
If these checks do not reveal the source of the problem and there is no
output in one or more treatment modes, the Stim Board is faulty.
