General Troubleshooting Hints
Instrument problems may not always result in error messages. Proper
instrument performance is determined by the quality of the results. Even if
your instrument turns on, passes its self tests, and operates without
generating error messages, it may not be functioning perfectly. The results of
measurements can provide hints for troubleshooting if measurement results
are less than optimal.
During a typical power on sequence the following events occur:
• the power switch LED will ignite and remain on,
• the front panel LED will turn yellow, then flash red, green, and stay yellow,
• the fan speed will decrease,
• the shutter will close, if you listen carefully you may here a click,
• the front panel LED will turn green.
The green front panel LED indicates successful completion of the self test
sequence.
Your software may be set so that lamp ignition does not automatically occur
during power on. In this case use your software to ignite the deuterium and
tungsten lamps.
