Initial Setup for the NI PXIe-4353
You must configure the module in Measurement & Automation Explorer (MAX) to communicate with
NI-DAQmx.
Complete the following steps to configure a module in MAX. Refer to the
NI SC Express 4353
Installation Guide and Terminal Block Specifications
for complete installation instructions.
1.
Install the NI-DAQmx driver software.
Caution
Always have the PXI Express chassis powered off when inserting a module.
2.
Insert the module into an available slot in the PXI Express chassis.
3.
Attach the CAL-4353 to the NI PXIe-4353.
Note
The CAL-4353 must be within its calibration interval and if it is not, you must calibrate the
CAL-4353 before calibrating the NI PXIe-4353 module.
4.
Power on the chassis.
5.
Launch MAX.
6.
Expand
Devices and Interfaces
to confirm that MAX detects the module and terminal block.
The terminal block should appear beneath its associated module.
7.
Right-click
NI PXIe-4353
and select
Self-Test
to ensure that the module is working properly.
Note
You can also perform the self-test operation programmatically, using the DAQmx Self-Test
Device VI or the equivalent C/.NET functionality.
Verifying Module Operating Temperature Changes
A module operating temperature greater than ±10 °C since the previous calibration adjustment can
cause you to incorrectly calibrate your module. The onboard temperature sensor on the module can be
used to verify that this condition does not exist. Complete the following steps to compare the current
module temperature to the temperature measured during the last calibration.
1.
Launch MAX.
2.
Select
My System»Devices and Interfaces»Chassis 1»NI PXIe-4353
.
Note
MAX assigns a chassis name for each chassis in an application. This document uses Chassis 1.
In your application, use the appropriate name assigned to your chassis by MAX.
3.
Click the
Calibration
tab.
If the difference between the current operating temperature and the operating temperature from the
last calibration adjustment is greater than 10 °C, the limits in the calibration tables are not valid.
Note
You can also query the temperatures programmatically, using the DAQmx Calibration Info
property node or the equivalent C/.NET functionality.
Note
The temperature reading returned by the module is an internal temperature. Typically, the
internal temperature is approximately 10 °C warmer than the ambient temperature.
If the module temperature difference is outside the maximum range, you should choose one of the
following options:
•
Recalculate the test limits to include the additional error due to temperature drift. Refer to the
NI PXIe-4353 Specifications
for more information.
•
Change the system so that the operating temperature will be closer to the temperature recorded
during the last calibration adjustment.
