To ensure the quality of the calibration data, sensors should be installed into 2 of the calibration samples. This provides a record of the exact temperature history of the samples. This is particularly important to track the temperature of the samples on-site, and in transit to the lab. In either cool or warm weather this is critical to understanding the maturity of the samples at low ages. Once prepared, the samples should be stored together at all times, including samples containing the sensors.
Firstly, ensure that you have the necessary equipment available at the time of the calibration. Calibration can be performed with any of Converge’s temperature sensors. General guidance is provided here, although the exact details may vary from one system to another. Articles showing how each type of sensor should be installed can be found by searching 'Calibrate with Signal' or 'Calibrate with Mesh'.
In general, sensors should be registered prior to the preparation of samples using an easily identifiable name (eg. “Calibration sensor 1 (<mix name>)” and “Calibration sensor 2 (<mix name>)”, replacing <mix name> with the name of your mix).
Once registered, verify that the sensors are recording temperature data using the app (if using the Converge Mesh system, sensors will need to be connected to their Nodes too, and data will only be visible if a Hub is nearby).
When sample preparation begins on-site, these sensors should be installed into the centre of the first and second samples, prior to the other samples being prepared. The time at which the sensors were placed into the cubes should also be recorded.
