Briefly describe the working principle of the data processing and storage unit of the furnace temperature tester.

Core conclusion: The data processing and storage unit of the furnace temperature tester receives digitized temperature signals, performs calibration conversion and time correlation for storage, while supporting key parameter calculation and data export.

1. Signal Reception and Calibration Conversion

• Receive the digitized signal after A/D conversion, which has undergone amplification and filtering.
• Convert the digitized signal into accurate actual temperature values based on the sensor’s calibration coefficients to correct measurement deviations.

2. Data Correlation and Calculation

• The microcontroller unit (MCU) matches each temperature value with a timestamp to establish a "temperature-time" correspondence.
• Some devices can real-time calculate key process parameters such as heating rate, holding time, and peak temperature.
