The software allows you to cycle through a number of measurement points. Once done, committing the calibration will apply the calibration to the K-TCxx, and measurement accuracy will be improved.

Pressing the Load Button Loads the calibration contained in the K-TCxx and displays them on the screen.

You may use this function if you wish to check that the K-TCxx is calibrated.

Alternatively, press the start button and attach the appropriate thermocouple test signals to the inputs of the K-TCxx in order to cycle through the test points in order to calibrate the K-TCxx for maximum accuracy: Select the Channel of the Calibration Point you wish to calibrate by either clicking the Radio Button on the channel.
Or by clicking on the point you wish to calibrate in the field to the right
Adjust the input temperature from the calibrated test equipment that you are using to match the voltage for the test point: ![](https://1039220062-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FRhWtYvkHNZy7Jvdnc3wk%2Fuploads%2FLfevmOQkw0aKszh3A5GB%2Fimage.png?alt=media\&token=20dbd892-4753-4577-824c-b93c96444f59) Press the Start button: If the input temperature is stable and correct, the calibration of the channel will be updated as follows: ![](https://1039220062-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FRhWtYvkHNZy7Jvdnc3wk%2Fuploads%2FQSVTdQSRTopxLOXLotdB%2Fimage.png?alt=media\&token=c613fdcf-6772-4307-8a15-fa668cb13cc8) If it is not, you will receive a warning:
Repeat the steps above until you have calibrated all the calibration points.

Once you have configured the K-TCxx as desired, click Commit to send the configuration to the K-TCxx. If you make a mistake and wish to clear the calibration, you can also use the Clear button.

This will save the calibration to the K-TCxx and create a report detailing the calibration:
--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.influxtechnology.com/support_guides/k-series-product-manual/k-series-product-manual/k-tc-logger-manual/using-the-k-tcxx-cal-software/calibrating-the-k-tcxx.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
