WARNING!
Do not attach or remove any cables while the NIRvana-LN system is
powered on.
Recommended troubleshooting guidelines are available for many issues that may occur
while working with a NIRvana-LN system. Refer to
Table 10-1 for additional information.
10.1 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 detector vacuum enclosure. Turn off the detector, carefully
remove liquid nitrogen from the detector (if applicable,) and have the detector repumped
before resuming normal operation. Contact Customer Support for further instructions. Refer
to
Contact Information on page 120 for additional information.
