Ensure that the PXI chassis fan speed is set to HIGH, that the fan filters (if present) are
clean, and that the empty slots contain slot blockers and filler panels. For more
information about cooling, refer to the
Maintain Forced-Air Cooling Note to Users
document available at

Plug the PXI chassis and any other instrument standards into the same power strip to
avoid ground loops.

As-Found and As-Left Limits
The as-found limits are the published specifications for the PXIe-5423. NI uses these limits to
determine whether the PXIe-5423 meets the specifications when it is received for calibration.
Use the as-found limits during initial verification.
The as-left calibration limits are equal to the published NI specifications for the PXIe-5423,
less guard bands for measurement uncertainty, temperature drift, and drift over time. NI uses
these limits to reduce the probability that the instrument will be outside the published
specification limits at the end of the calibration cycle. Use the as-left limits when performing
verification after adjustment.
Calibration Overview
Install the PXIe-5423 and configure it in NI Measurement & Automation Explorer (MAX)
before calibrating.
Calibration includes the following steps:
1.
Self-calibration—Let the PXIe-5423 warm up for 15 minutes before self-calibrating the
PXIe-5423 by clicking the
Self-Calibrate
button in MAX or calling niFgen Self Cal.
2.
Verification—Verify the existing operation of the device. This step confirms whether the
device is operating within the published specification prior to adjustment.
