Record the device identifier MAX assigns to the hardware. Use this identifier when
programming the PXIe-5172.
Note
When you install, uninstall, or move an NI-RIO device in your system,
resource identification of your NI-RIO devices may change. Whenever any of
these changes occur, verify resource identification of all your NI-RIO devices
in MAX, and, if necessary, make changes to your software and documentation.

Self-Calibration
Self-calibration adjusts the PXIe-5172 for variations in the module environment. Perform a
complete self-calibration after first installing your module and letting it warm up for 15
minutes.
Note
Warm-up begins after the chassis is powered, the device is recognized by the
host, and the device is configured using the instrument design libraries or
NI-SCOPE. Running an included sample project or running self-calibration using
NI MAX will configure the device and start warm-up.
The PXIe-5172 modules are externally calibrated at the factory; however, you should perform
a self-calibration in any of the following situations:
•
After first installing the PXIe-5172 into your chassis
•
After any module in the chassis is installed, uninstalled, or moved
•
When the system is in an environment where the ambient temperature varies or the
module temperature has drifted more than ±5 °C from the temperature at the last self-
calibration
•
To periodically adjust for small performance drifts that occur with product aging
To programmatically self-calibrate the PXIe-5172 when using instrument design libraries, use
