Clear relevant registry items one at a time and then reconfigure the digitizer and any
Telegraphed instrument. Try clearing items such as Digitizers, Clampex software,
AxoScope software, pCLAMP software, and Common Settings.
Note: For software items, all customized window settings are lost, but signal names
and protocols save.
Run a check on the computer hard drive structure and RAM.
Call Molecular Devices Technical Support if the problem persists.
Problems With Data Throughput
Try the following if you experience data throughput problems.
If decreasing the number of analog input channels or the sampling rate improves
performance, you likely have a data throughput problem. Verify that the digitizer is
connected to a high-speed USB 2.0 port on your computer. See
. If the digitizer is connected to a USB hub, remove any other
devices connected to the hub, or bypass the hub.
Try the digitizer on a faster computer. CPU speed is only one part of the system. Other
relevant components include hard drive speed, RAM speed, and front-side bus speed.
To improve data-throughput related acquisition performance problems in Clampex
software or AxoScope software try the following:
In Configure > Lab Book Options, select Never log any events.
In Configure > Program Options, select Disable screen saver during data acquisition.
