B. Working Principle
The DT-302-1 works by sensing temperature through the TP01 temperature probe. When the probe is placed on or into the target area, it detects the temperature and sends a signal to the instrument. The thermometer processes this signal and converts it into a temperature value displayed on the large LCD screen. The Data Hold function allows the user to freeze the displayed value so the reading can be noted even after the probe is removed.
