When I purchase a device or use NI's Calibration Services, I get a Certificate of Calibration that has many different dates and pieces of information. What do those mean?
The Instrument Certificate that NI provides is divided into four main sections, as shown in the image below:
The first section of the document refers to your device. (For example: USB-6341). This section contains the information regarding the calibration status of your product. You will find here:
NI lists information about the instruments used to test your device to assure you of the validity of our calibration testing: instrument manufacturer, model, tracking number, calibration date, and calibration due date.
Besides the hard data provided, NI includes some texts with explanations and disclosures regarding your device and the information we present. This section includes notes that are relevant to you and the calibration auditors when interpreting the numbers shown in the document.
Some NI devices or modules do not need to be calibrated and therefore do not have a Calibration Interval. Any NI device or module that has Warranted Specifications will need to be calibrated, and should have a Calibration Interval listed in the Specifications or Datasheet.
If your device does not have Warranted Specifications and does not require calibration then neither the Specifications nor the Datasheet will define a Calibration Interval. Similarly, if your device does not require calibration and you use the Instrument Certificate Generator, no Calibration Date or Calibration Interval will be listed in the Board Information.
