The Instrument Is Not Scanning; The Mct Detector Is Warm - Thermo Scientific Nicolet iS10 Using Manual

The instrument is not scanning

Note: After 1 hour without data collection activity, the interferometer automatically stops
scanning and the Scan light stays on. This is normal. Any data collection activity will cause the
interferometer to begin scanning again.
1.—Turn your instrument on (if it is not already turned on).
2.—Start OMNIC (or other instrument software you are using).
3.— Make sure the system has been on for at least 15 minutes (one hour for best results),
and then align your instrument. If your instrument does not resume scanning, proceed to
the next step.
4.—Turn off the power to the computer and the instrument. Leave the power off for 15
seconds. Turn your instrument on and wait until the start-up diagnostics finish. Then turn
on the computer and restart OMNIC.
5.—Open the Diagnostic tab of the Experiment Setup dialog box and change the Detector
selection to Reference Detector.
If the instrument scans normally (look for a flashing Scan indicator and an interferogram),
the problem is probably related to the sample or the detector. Make sure that the sample
compartment beam is not blocked, and check the Diagnostic tab of the Experiment Setup
dialog box to make sure the detector is recognized. If it is not, contact us for assistance.
6.—Check all of the indicators on the Diagnostic tab of the Experiment Setup dialog box. Click
any indicator that has a red slash through it to view diagnostic information about the
component.
If the laser frequency is outside the specified range, contact us to have the electronics
module replaced. If the laser voltage or current is outside the specified range, contact us
for assistance.
If the temperature is not in the acceptable range, make sure the cooling vents on the back
of the instrument are not blocked and nothing is stacked on top of the instrument.
Maintain at least 30 cm (12 in) of clearance behind the instrument and 64 cm (25 in) of
clearance above the table. Make sure the ambient temperature is between 16° and 27°C
(60° and 80°F), and make sure that the power supply vents are not blocked.
8.—Contact us for assistance.

The MCT detector is warm

1.—Cool the detector.
2.—Check the detector dewar for signs of leaks. If necessary, contact us to restore the dewar
vacuum.
3.—Contact us for assistance.
