Each channel consists of two terminal connections specific to that channel as shown in Table 2
and must be verified and adjusted individually. Do not make serial or parallel connections for
verification or adjustment.
Test Conditions
The following setup and environmental conditions are required to ensure the NI PXIe-4322
meets published specifications.
•
Keep connections to the NI PXIe-4322 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-4322 are secure.
•
Use shielded copper wire for all cable connections to the TB-4322. Use twisted-pairs wire
to eliminate noise.
•
Maintain an ambient temperature of 23 °C ± 5 °C.
•
The NI PXIe-4322 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 NI PXIe-4322 measurement
circuitry is at a stable operating temperature.
•
Ensure that the 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-4322 and TB-4322 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 with MAX, it is assigned a device identifier.
Each function call uses this identifier to determine which DAQ device to verify or,
verify and adjust.
