Appendix E: Troubleshooting
WARNING!
Do not attach or remove any cables while the camera
system is powered on.
Recommended troubleshooting guidelines are available for many issues that may occur
while working with a NIRvana HS system. Refer to
Table E-1 for additional information.
E.1 Baseline Signal Suddenly Changes
A change in the baseline signal is normal if the temperature, gain, or speed setting has
been changed. If this occurs when none of these settings have been changed, there
may be excessive humidity in the camera vacuum enclosure. Turn the camera off and
contact Teledyne Princeton Instruments Customer Support. Refer to
Contact
Information on page 100 for complete contact information.
E.2 Camera Stops Working
Problems with the host computer system or software may have side effects that appear
to be hardware problems. If you are sure the problem is in the camera system hardware,
begin with the following simple checks:
• Turn off all AC power.
• Verify that all cables are securely fastened.
• Turn the system on.
If the system still does not respond, contact Teledyne Princeton Instruments Customer
Support.
