Test Conditions
The following setup and environmental conditions are required to ensure the PXIe-4302/4303 meets published specifications.
· Keep connections to the PXIe-4302/4303 as short as possible. Long cables and wires act as antennas, picking up extra noise that can affect measurements.
· Verify that all connections to the TB-4302 are secure.
· Use shielded copper wire for all cable connections to the TB-4302. Use twisted-pair wire to eliminate noise and thermal offsets.
· Maintain an ambient temperature of 23 °C ±5 °C. The PXIe-4302/4303 temperature will be greater than the ambient temperature.
· Keep relative humidity below 80%.
· Allow a warm-up time of at least 15 minutes to ensure that the PXIe-4302/4303 measurement circuitry is at a stable operating temperature.
· Ensure that the PXI/PXI Express chassis fan speed is set to HIGH, that the fan filters are clean, and that the empty slots contain filler panels. For more information, refer to the Maintain Forced-Air Cooling Note to Users document available at ni.com/manuals.

Initial Setup
Refer to the NI PXIe-4302/4303 and TB-4302/4302C Installation Guide and Terminal Block Specifications for information about how to install the software and hardware and how to configure the device in Measurement & Automation Explorer (MAX).

Note When a device is configured in MAX, it is assigned a device identifier. Each function call uses this identifier to determine which DAQ device to verify or to verify and adjust. This document uses Dev1 to refer to the device name. In the following procedures, use the device name as it appears in MAX.

Accuracy Verification
The following performance verification procedures describe the sequence of operations and provides the test points required to verify the PXIe-4302/4303. The verification procedures assume that adequate traceable uncertainties are available for the calibration references.

The PXIe-4302/4303 has 32 independent analog input channels. The input range of each channel can be set to 10 V or 100 mV. You can verify the accuracy of either range for any or all of the channels depending upon your desired test coverage.
