Note:
The pin arrangements for the Bio Amp and the Dual Bio Amp are diff erent;
the Bio Amp cables are not interchangeable. (The Bio Amp is supplied with a 3-lead
Bio Amp cable, whereas the Dual Bio Amp is supplied with a 5-lead Bio Amp cable.)
Troubleshooting
This section describes the common problems that can occur when using the Bio
Amp with your PowerLab recording unit. It covers how these problems are caused,
and what you can do to alleviate them. If the solutions here do not work, refer to
earlier chapters, the LabChart Help Center, and your PowerLab Owner’s guide for
possible remedies. If none of the solutions here or elsewhere are of help, then
consult your ADInstruments representative.
Most of the problems that users encounter are connection problems, and can
usually be fixed by checking connections and starting up the hardware and
soft ware again. Very rarely will there be an actual problem with the front-end or
the PowerLab.

C cable or one or more BNC-to-BNC cables from the Bio Amp to the PowerLab
are not connected, have been connected incorrectly (to the wrong input, for
instance), or are loose.
•
Turn everything off . Check to see that all cables are firmly seated and
screwed in. BNC cables from the Bio Amp must be connected to a positive
input on the PowerLab. Make sure the input is the same channel from which
you expect to use the front-end in the soft ware. Start up again to see if this
has fixed the problem.
You are using an early version of LabChart.

Upgrade to the latest version of the soft ware. Contact your ADInstruments
representative for information.

Replace the cable and try again. Immediately label all cables proved faulty
so that you don’t use them again by accident.
The Bio Amp is faulty
•
This is the least likely event. If the front-end will not work properly aft er
the previous measures, then try using it on another PowerLab. If the same
problems recur with a second PowerLab, the front-end may be faulty.
Contact your ADInstruments representative to arrange for repairs.
On starting up the soft ware, an alert indicates that there is a problem with the front-
end or driver
The correct Bio Amp driver is not installed on your computer.
