Changing the Source

Thermo Scientific
Note Turn the locking ring on the power supply connector until you feel it snap into
place.
3. Connect the new power supply.
Simply reverse the order that you disconnected the power cords in the previous step.
4. Turn on the instrument.
The scan bar on the instrument touch panel will cycle red, yellow and green until the
instrument is ready and then change to a solid-pulsing, green light. If your instrument
does not function normally, turn off the power and check the cable connections between
the power supply, the instrument, and the wall outlet or power strip. If the connectors are
seated properly and the instrument still does not function normally, contact us for
assistance.
Both mid-IR and near-IR sources are available for your spectrometer. This procedure explains
how to change from one kind of source to the other.
Time needed:
25 minutes or less
Tools needed:
• 4-in-1 tool (included with your instrument)
• Finger cots, gloves, or laboratory tissue
• Alternate or duplicate source
NOTICE
• Use only Thermo Scientific certified replacement parts. To order parts, contact us.
• Never touch a source element with your bare fingers. Skin oils or other deposits on
the element will shorten its life. Always use clean finger cots, gloves, or clean
laboratory tissue when handling a source.
Note A spare source, or an alternate source, can be stored in a holder in the same
compartment as the 4-in-1 tool (above the desiccant compartment).
CAUTION The source becomes extremely hot when the instrument is powered on. Always
allow the source to cool for at least 15 minutes after the instrument is powered off before
you work with it.
1. Turn off your instrument, wait 15 minutes for the source to cool, and then remove the
Smart Accessory or open the sample compartment cover.
