Step 3: Upload Calibration Files¶

This step uploads and parses sensor calibration files so calibration coefficients can be applied during data processing.

Prerequisites

Sensor record created in CORIOLIX (Step 1)
Access to the sensor calibration file(s)

Overview¶

For some sensors, calibration coefficients are required to convert measurements from raw engineering units (like volts or counts) to scientific units. Recent calibration files must be uploaded to CORIOLIX before data collection and processing begins.

During the upload of a calibration file, CORIOLIX will determine whether the file is a parseable calibration file known to CORIOLIX.

If the file is parseable, CORIOLIX will then:

Parse the uploaded file, extracting the date of calibration and the calibration coefficients
Store the calibration date and calibration coefficients in a CORIOLIX database table
Make the calibration information accessible to the data processing code

During real-time processing, the relevant calibration coefficients (based on the calibration date) are applied.

When the file upload is complete, the uploaded file is stored on the server and made available on the CORIOLIX sensor details page and the documents page.

Best Practices

Upload all calibration files and certificates regardless of whether they are needed for processing or not
If a parseable copy needs to be made of a calibration file, upload both the parseable version and original version
Fill out the document upload form as completely as possible
Assign calibration files to the document category "Calibration File(s)"
Assign the calibration file to the specific sensor it applies to

After creating the new .cal file, upload both the original PDF file and the new .cal file to CORIOLIX separately. CORIOLIX will automatically parse the .cal version.

FLNTURTD¶

WET Labs {Sea-Bird WETLabs} ECO FLNTU(RT)D combined fluorometer and turbidity sensor

For the ECO FLNTU(RT)D, WET Labs provides a PDF version of the calibration file only. To make a parseable version for CORIOLIX, the contents of this file must be manually copied over to a text file in the exact format shown below. Replace the values in the example with those from the PDF calibration sheet.

The new text file name must end in '.cal'. It is recommended that the FLNTU serial number and the calibration date be included in the filename (e.g. FLNTURTD8749_Feb2025.cal).

Example: FLNTURTD8749_Feb2025.cal
