Running Self-Calibration
Running self-calibration enables the PXIe-5163 to yield full performance over its operating
temperature range and two-year external calibration cycle.
Before running self-calibration, warm up the PXIe-5163 for at least 15 minutes.
Note
Warm-up begins after the chassis and controller or PC is powered and
NI-SCOPE is loaded and recognizes the PXIe-5163.
PXIe-5163 modules are externally calibrated at the factory, but for optimal performance, use
self-calibration in any of the following situations:
•
After first installing the PXIe-5163 in 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 previous self-calibration
•
To periodically adjust for small performance drifts that occur with product aging
•
When 90 days have elapsed since the previous self-calibration
Tip
You can use the nodes on the NI-SCOPE External Calibration palette to
programmatically return the date and module temperature of the previous self-
calibration. You can also view this information by selecting the device in MAX.
Self-calibrate the PXIe-5163 programmatically in NI-SCOPE or on demand in MAX.
Option
Description
NI-SCOPE
Use the Self Calibrate node to self-calibrate the module.
MAX
Select the device in the
Devices and Interfaces
menu and click the
Self-
Calibrate
button.
When the two-year external calibration interval expires, an external calibration is required to
ensure performance that is within specification over the subsequent two years.
