• Ensure that the PXI chassis fan speed is set to HIGH, that the fan filters (if present) areclean, and that the empty slots contain slot blockers and filler panels. For moreinformation about cooling, refer to the Maintain Forced-Air Cooling Note to Usersdocument available at ni.com/manuals.• Plug the PXI chassis and any other instrument standards into the same power strip toavoid ground loops.PasswordThe default password for password-protected operations is NI.Related InformationAdjusting the PXIe-5413 on page 14Setting the Calibration Date and Due Date on page 18Calibration IntervalRecommended calibration interval 2 yearsAs-Found and As-Left LimitsThe as-found limits are the published specifications for the PXIe-5413. NI uses these limits todetermine whether the PXIe-5413 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-5413,less guard bands for measurement uncertainty, temperature drift, and drift over time. NI usesthese limits to reduce the probability that the instrument will be outside the publishedspecification limits at the end of the calibration cycle. Use the as-left limits when performingverification after adjustment.Calibration OverviewInstall the PXIe-5413 and configure it in NI Measurement & Automation Explorer (MAX)before calibrating.Calibration includes the following steps:1. Self-calibration—Let the PXIe-5413 warm up for 15 minutes before self-calibrating thePXIe-5413 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 thedevice is operating within the published specification prior to adjustment.3. Adjustment—Perform an external adjustment of the calibration constants of the device.The adjustment procedure automatically stores the calibration date and temperature onthe EEPROM to allow traceability.PXIe-5413 Calibration Procedure | © National Instruments | 5
