Unpack and Install the Module
Remove the packaging and inspect the module. Contact NI if the module is damaged. Do not
install a damaged module.
Caution The module is static sensitive. Always properly ground yourself and the
equipment when handling or connecting to the module.
Complete the following steps to install the NI PXIe-4302/4303 module while referring to
Figures 1 and 2:
Note To maintain forced air cooling in the PXIe system, refer to the Maintain
Forced-Air Cooling Note to Users.
1. Plug in your chassis before installing the NI PXIe-4302/4303. The power cord grounds the
chassis and protects it from electrical damage while you install the module.
2. Make sure the chassis is powered off.
Caution To protect yourself, the chassis, and the NI PXIe-4302/4303 from
electrical hazards, leave the chassis powered off until you finish installing the
NI PXIe-4302/4303 module.
3. Touch a metal part on the chassis to discharge any accumulated static electricity.
4. Identify a supported PXI Express slot in the chassis. NI PXIe-4302/4303 modules can be
placed only in PXI Express Peripheral slots, PXI Express Hybrid Peripheral slots, and PXI
Express System Timing slots. Refer to the chassis documentation for details.

Cold-Junction Compensation (TB-4302 Only)
The TB-4302 contains a temperature sensor that is used to measure the temperature of the
terminal block for cold-junction compensation, which is performed when computing the
thermocouple temperature measurement.
Cold-junction compensation is the process of measuring the temperature of the screw terminal
junction for the thermocouple and applying a representative compensating temperature to the
temperature measured by the thermocouple channel. The accuracy of the cold-junction
temperature measurement contributes to the accuracy of the overall thermocouple temperature
measurement. The TB-4302 is designed to ensure high-accuracy cold-junction temperature
measurements under a variety of conditions; however, care must be taken to ensure the best
possible accuracy. Refer to the Minimizing Thermal Gradients section for guidelines to
minimize thermal gradients that can impact the CJC accuracy. Refer to the TB-4302 section for
the CJC accuracy specifications.
Minimizing Thermal Gradients
Thermal gradients can be caused by changes in the ambient air temperature near the terminal
block, heat sources from other devices near the terminal block, or by the thermocouple wire if it
conducts heat to or away from the terminal junctions. For optimal CJC accuracy performance,
ensure that changes in ambient temperature and temperature gradients near the terminal block
are kept to a minimum.
Follow these guidelines to minimize thermal gradients that can impact the CJC accuracy:
• Use the smallest gauge thermocouple wire suitable for the application. Smaller wire
transfers less heat to or from the terminal junction.
• Run thermocouple wiring together near the terminal block to keep the wires at the same
temperature.
• Avoid running thermocouple wires near hot or cold objects.
• If you connect any extension wires to thermocouple wires, use wires made of the same
conductive material as the thermocouple wires.
• Minimize adjacent heat sources and air flow across the terminal block.

• Keep the ambient temperature as stable as possible.
• Keep the terminal block, module, and chassis in a stable and consistent orientation.
• Install the PXIe filler panels in any unused slots.
• When stacking the system, avoid stacking the chassis above a heat source as heat rises and
can introduce error.
• Allow the thermal gradients to settle after a change in system power or in ambient
temperature. A change in system power can occur when the system powers on. Refer to the
warm-up time in the NI PXIe-4302/4303 Specifications for more information.
• If your PXIe chassis has fan filters, clean or replace them regularly to ensure proper system
cooling. Refer to the PXI/PXI Express Chassis Fan Filter Kit document for more
information.
Note Refer to the Maintain Forced-Air Cooling Note to Users for more
information about maintaining optimal forced-air cooling for PXI/PXI Express
devices.
