In this video, we’ll cover how to view calibration records in Kor Software. You can also use the EXO Handheld or the Kor Mobile App.
The calibration is applied to and stored in each EXO Smart Sensor. However, the Calibration Record is stored on the PC or device with which the calibration was performed. These records are convenient for tracking sensor performance and record keeping. They may be viewed within the software, printed, or exported to share with colleagues. You may view these records without being connected to the sonde.
In Kor Software, navigate to the Calibration screen. Then click Find Calibration Records. Here you can find all of the calibration records stored in the Kor Database. There are filters on the left panel to narrow down your results. Clicking Recently Downloaded will only display records from the last 30 days. You can also specify a date range to narrow down your results.
Other filters include Sensor Type, Calibration Parameter, Instrument or Sonde serial number, and Sensor serial number. Kor Software allows for an optional User Login to track who is performing each calibration. You can even search by user name if you utilize this feature.
Let’s filter by specific conductance calibrations. The results show sensor type, parameter that was calibrated, sensor serial number, calibration date and time, instrument serial number, and technician or User name. You can select and view a single calibration record or multiple records. I performed a multi-sensor calibration for specific conductance, so I will select all seven of these and click View Selected Calibration Records. This takes us back to the Calibration Records Panel. Here we can choose each individual sensor cal record to view the full calibration details.
Let’s now take a look at a calibration record. These records all include the Sensor Type, Last Calibration Time (if known), the calibration start time, and end time. Additionally, the record includes General information about the sensor and sonde, including the calibrated parameter; here we can see Specific Conductance, the Instrument serial number, the instrument firmware version, the instrument type, the sensor serial number, the sensor firmware version, the ‘calibrated by’ user name (if known), the Calibration status, and the QC Score.
Next, there is information about each calibration point. This includes the pre-calibration value, the post-calibration value, the temperature reading at the time of calibration, the standard value that we calibrated the parameter to, and the stability. Some calibration records include sensor-specific information. For conductivity, we see a cell constant. This is a good indicator of how the sensor is performing. Other examples of sensor-specific information include the ODO Gain, the pH millivolt slope, and millivolts per decade. Please refer to the EXO User Manual for more information about the optimal values for these results.
Finally, there is an option to add Notes to each calibration record. These notes cannot be deleted once they are saved.
Kor allows you to export these records for convenience. Choose a CSV if you would like to open this in a spreadsheet. You can choose XML if you would like to transfer to another instance of Kor Software. I’ll export it to a CSV. Once the export is complete, we can see all of the selected calibration records are included in the same file. Any notes that were saved will be included with the export.
Keeping a record of your sensor calibrations is strongly recommended and essential for quality assurance and control. Kor Software makes it easy to manage your EXO Sensor Calibration Records! Please be sure to check out our other EXO University videos, and thanks for watching!
