Appendix A – Troubleshooting
First thing to do:
It is important that you ensure you've got the latest version of firmware
(software that's inside the DCA Pro instrument) and the latest version of PC
software. You can do this by connecting the unit to your PC and selecting the
"Help" menu and then click on "Check for Updates".
It is possible that a firmware update and/or a PC software update will resolve
your problem.
Here's a further guide to helping you with your DCA Pro if you're having
problems:
Problem

"Disconnected" even when
the DCA Pro is connected
and powered up.

Possible Solutions
Unplug USB, wait a few seconds and plug
back in.
Try a different USB socket on your PC.
Restart your PC.
Uninstall and then Re-install the software.
It is possible that your battery is in poor
condition. Replace with a new Alkaline
AAA battery.
Most semiconductors have very wide
tolerances and even identical transistor types
can show huge gain variation between them.
Characteristics shown in datasheets may be
specified at different test conditions
compared to the test conditions used by the
DCA Pro.
