10. Troubleshooting
If a system is not operating properly, please contact a Campbell Scientific support
engineer for assistance. When using sensors, peripheral devices, or comms
hardware, look to the manuals for those products for additional help.
Note If a Campbell Scientific product needs to be returned for repair or
recalibration, a Return Materials Authorization
(p. 5)
number is first required.
Please contact a Campbell Scientific support engineer.

Troubleshooting — Essential Tools
•
Multimeter (combination volt meter and resistance meter). Inexpensive
($20.00) meters are useful. The more expensive meters have additional
modes of operation that are useful in some situations.
•
Cell or satellite phone with contact information for Campbell Scientific
support engineers. Establish a current contact at Campbell Scientific
before going to the field. A support engineer may be able to provide
you with information that will better prepare you for the field visit.
•
Product documentation in a reliable format and easily readable at the
installation site. Sun glare, dust, and moisture often make electronic
media difficult to use and unreliable.

Troubleshooting — Basic Procedure
1. Check the voltage of the primary power source at the POWER IN terminals
on the face of the CR3000.
2. Check wires and cables for the following:
o
Loose connection points
o
Faulty connectors
o
Cut wires
o
Damaged insulation, which allows water to migrate into the cable.
Water, whether or not it comes in contact with wire, can cause
system failure. Water may increase the dielectric constant of the
cable sufficiently to imped sensor signals, or it may migrate into the
sensor, which will damage sensor electronics.
3. Check the CRBasic program. If the program was written solely with Short
Cut, the program is probably not the source of the problem. If the program was
written or edited with CRBasic Editor, logic and syntax errors could easily
have crept into the code. To troubleshoot, create a stripped down version of
the program, or break it up into multiple smaller units to test individually. For
