Replace the Source
The IR source is easily accessible from the bottom of the spectrometer and can be replaced
without having to remove the spectrometer’s cover.
Tools and materials needed
• A #1 Phillips head screwdriver
• Source Replacement Kit
Time needed: 25 minutes or less
To replace the source
1. Turn off and disconnect the spectrometer.
a. Turn off the instrument and unplug the power cord.
b. Disconnect any cables from the instrument, such as the Ethernet cable or USB
devices.
c. If the spectrometer or an installed accessory is purged, disconnect the purge lines
from the spectrometer and the accessory (quick connect fittings stop the flow
automatically). See Install and Maintain a Purge Kit for more information.
d. Remove any installed accessories from the instrument.
CAUTION Before replacing the source, turn off the instrument. Replace the source only
with replacement parts supplied by us.
CAUTION The source becomes extremely hot while you are using the instrument.
Wait at least 10 minutes after turning the instrument off before you perform the
next step.

c. Use a #1 Phillips head screwdriver to fully loosen the three captive screws that hold
the source in place.
d. Swing the bale out. Steady the instrument with one hand and pull firmly on the bale
to pull the source straight out of the instrument.
3. Insert the new source.
a. Make sure the three captive screws are straight and then slowly insert the source into
the cavity until the source mount is flush with the instrument.
b. Tighten the screws to secure the source and snap the bale into its storage position.
4. Reconnect and power on the spectrometer.
a. Carefully return the instrument to its upright position and reconnect any cables you
removed.
b. Replace the desiccant. See Replace the Desiccant for instructions.
Because the internal optics are exposed to the atmosphere when removing the source,
the desiccant should always be replaced after replacing the source.
NOTICE 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 element.

5. Align the spectrometer and verify its performance.
Wait until the spectrometer’s LightBar indicates that it is warmed up and ready for use
before proceeding.
You can align the spectrometer and verify performance using either the desktop or
touchscreen interface.
To use the touchscreen interface, perform the following steps:
a. Align the spectrometer.
i. Open OMNIC Paradigm software.
ii. On the Home screen, touch the Diagnostics icon to open the Diagnostics view
and navigate to the Align tab.
iii. Touch Align to begin alignment.
b. Verify the instrument’s performance.
i. Using the touchscreen interface, beginning on the Home screen, navigate to the
Workflows tab.
ii. Select the Nicolet FTIR - Factory Qualification workflow and touch the Run
icon. Follow the on-screen prompts to complete the workflow.
To use the desktop interface, perform the following steps:
a. Align the spectrometer.
i. Open OMNIC Paradigm software.
ii. Open the Acquire Data menu and select Diagnostics > Align Spectrometer.
iii. Click Start and follow the on-screen prompts. Click Close when complete to
return to the dashboard.
b. Verify the instrument’s performance.
In the Workflows pane, double-click Nicolet FTIR - Factory Qualification and
follow the on-screen prompts.
6. Replace any accessories that you removed earlier.
WARNING To ensure a good ground connection and avoid shock hazard, do not
use an outlet that is connected to a conduit ground. The ground must be a
noncurrent-carrying wire connected to earth ground at the main distribution
box.
Note Do not install any sampling accessing until after you have aligned the
spectrometer and verified its performance
