7 Troubleshooting
The USB-UT350 utilizes the full amount of current available as outlined in the USB 2.0
specification. The real world implementation of USB 2.0 varies between computers and
some will provide more current to the device than others. If you are having difficulties
maintaining a steady signal at high pulse voltages, make sure that there are no other
devices drawing current from the USB. If this does not resolve the issue it may be
necessary to connect the external power adapter to the USB-UT or to use the device with
a different computer.
