Troubleshooting

This section describes most of the common problems that can occur when using your Power-
Lab unit. It covers how these problems are caused and what you can do to alleviate them. If
the solutions here do not work, earlier chapters or your software guide may contain possible
remedies. If none of the solutions here or elsewhere appears to help, then consult your ADIn-
struments distributor.
Most of the problems that users encoutner are connection problems and can usually be fixed
by checking connections and starting up the hardware and software again. Very rarely will
there be a problem with the PowerLab itself.
