    • The PXIe-5423 is warmed up for 15 minutes at ambient temperature. Warm up begins after the chassis is powered and the PXIe-5423 is recognized by the host and configured using NI-FGEN. • All test instruments are warmed up for at least the period of time stated in the documentation for each instrument and self-calibration is performed.

    EEPROM to allow traceability. 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. Reverification—Repeat the Verification procedure to ensure that the device is operating within the published specifications after adjustment.
