Peak Atlas DCA Pro User Guide
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".
Problem
PC software always says
"Disconnected" in the status
bar even when the DCA Pro is
connected and powered up.
Unit displays "Boost timeout"
on the LCD
Measured parameters don't
agree with the component data
sheet.
My voltage regulator is not
being identified.
Results are always wrong or
the unit fails to start correctly.
Feel free to contact us for technical assistance. Our contact details are shown at
the end of this user guide.
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 data sheets may be
specified at different test conditions compared to
the test conditions used by the DCA Pro.
Not all voltage regulators are stable when tested
outside their intended circuit with decoupling
capacitors and a load. The DCA Pro cannot
provide the ideal conditions for all regulators.
If the regulator requires a voltage greater than
about 9V to start regulating then it may have
difficulty testing your regulator.
If the displayed results are always wrong then it is
likely that the unit has been damaged due to a
charge/voltage on the probes. Contact us for help.
