5 Troubleshooting Guide
This section covers:
Tests that can be performed if you encounter a problem
What to do if your data does not look right
Instructions on how to return an instrument for repair
This section contains our yearlong experience in where to start looking if an instrument does not
behave as intended. If you encounter a problem, you should:
Work in a systematic way and do not neglect the obvious.
Get a good overview of the problem; make notes during the troubleshooting process.
Start by looking for simple causes such as incorrect baud rate, power not connected, bad
connections or incorrect serial port. If the system involves custom cables, power supply or the
like, first assemble and test the instrument using just the cables and battery that came with the
system. This is the easiest way to get the system to work, and if you have trouble, you can
always return to this setup to confirm that problems are not caused by a faulty instrument.
