Calibration Interval Recommendations for NI Hardware

Updated Jul 30, 2026

Issue Details

I have questions about the calibration requirements for my NI hardware:

  • How often should my unit be calibrated?
  • When does the calibration interval start?
  • Can I set a calibration interval that is different from the NI recommendation?

Solution

The appropriate calibration interval depends on the hardware being calibrated and the requirements of the application. The following information can help determine the best calibration schedule for your device.

 

How Often Should My Unit Be Calibrated?

 

Depending on your hardware and the nature of your application, NI recommends calibrating your hardware anywhere from once every six months to once every two years. The appropriate calibration interval can be determined based on the following factors: 

 

  • The NI-recommended calibration interval for your specific product, as listed in the product specifications. 
  • The reliability and accuracy requirements of your application. 
  • Environmental conditions, such as temperature, humidity, and vibration. 
  • The frequency and duration of use of the device. 

Following an appropriate calibration schedule helps ensure that the device continues to meet its specified performance and accuracy requirements.

 

When Does the Calibration Interval Start?

 

The calibration interval begins on the date the calibration is performed. The next calibration due date is calculated from the calibration completion date using the assigned calibration interval.

 

Can We Set Our Own Calibration Interval?

 

Yes. If your organization requires a calibration interval that differs from the NI-recommended interval, you can request a custom calibration interval when arranging calibration services. The requested interval can be configured in the calibration procedure and documentation so that the reported calibration due date aligns with your organization's requirements.

Additional Information

Organizations may choose a calibration interval based on internal quality standards, regulatory requirements, environmental conditions, historical performance data, and the criticality of the measurements being performed. If you are unsure which interval is appropriate for your application, review the product specifications and consult NI calibration services for guidance.
