SCXI-1503 Calibration Procedure 4 ni.com
• Allow a warm-up time of at least 30 minutes to ensure that the measurement circuitry is at a stable
operating temperature.
• Use shielded copper wire for all cable connections to the SCXI-1306 terminal block. Use
twisted-pair wire to eliminate noise and thermal offsets.
• Ensure that the SCXI chassis empty slots contain front and rear filler panels.
• Plug the SCXI chassis, computer, and the instrument standard into the same power strip to avoid
ground loops.
Calibration Procedures
The calibration process includes the following steps:
1. Initial Setup —Install the module and configure it in Measurement & Automation Explorer (MAX).
2. Self-Calibration —Adjust the self-calibration constants of the module.
3. Verification —Verify the existing operation of the module. This step confirms whether the module
is operating within the published specifications prior to adjustment.
4. Adjustment —Adjust the calibration constants of the module. The adjustment procedure
automatically stores the calibration date on the EEPROM. Go to

information about returning a module to NI for a factory calibration.
5. Reverification —Repeat the verification procedure to ensure that the module is operating within the
published specifications after adjustment.
These procedures are described in more detail in the following sections.
