HAM ThermoSense calibration
Ilias Dadis
Last Update 6 months ago
The HAM ThermoSense temperature recorders are equipped with special sensors. After conducting several tests, we can confidently state that they exhibit almost zero deviation from the actual temperature. This means that the temperature displayed in the application is quite accurate. At times, there may be a difference between the value shown in the application and the value indicated by the thermometer in our refrigerator. This difference is primarily due to the different positions of the two sensors. To minimize this variance, we have included an option in our application to calibrate the sensor. To calibrate the sensor, please follow the steps below.
Going to the calibration tab
- From the "Devices" tab, select the device you want and press the "More" button to go to the corresponding page
- Select the "Settings" submenu
- Press the "Advanced" button
- Press the "Calibration table (DEGREES)" button
- In the checkbox that appears, accept to display the calibration table
What I see in the calibration tab
- "Raw XXXX": it's temperature as read by the sensor
- "Output XXXXX": is the temperature as read by the sensor as read by our application.
- In the table, the measurement column is for the raw temperature while the reference column is for the output temperature
- The graph showing the linearity of the measured values
- Button for adding the Offset
What I do for the calibration
- Check that the table is empty, if not I delete any values from the corresponding button
- Calculate the difference between the raw temperature and the temperature I want to see (Desired-Raw = Final)
- Press the "Add offset" button
- Enter the value of my operation(If it is negative I put the corresponding symbol -)
- Confirm with "OK"
- Press the new button that has appeared "Submit (Calibration)"
Calibration risks
If you want to calibrate your recorder, make sure you have tried all other options first. When a sensor leaves our facility, it is already calibrated, meaning it has been tested and we are confident that its deviation is close to zero. However, by calibrating it again, we cannot guarantee the accuracy of the measurements.
