Measurement of thermal resistance
Thermistor measurement is good or bad, you first test the resistance in the indoor environment, and then hold the product test hand to see if the resistance is smaller, if the change shows normalSpecial instruments are to be used for accurate measurement
Thermistors are a type of sensitive element. They are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to their temperature coefficients. Thermistors are typically sensitive to temperature and exhibit different resistance values at different temperatures. When the temperature is higher, the higher the resistance value, the negative temperature coefficient thermistor (NTC) the higher the temperature, the lower the resistance value, they belong to the semiconductor device (PTC).
Test the resistance in the indoor environment first, then hold the product test with your hand to see if the resistance is small, if the change shows normal, otherwise it is not normal.Note: when testing, accurate measurements should be made with specialized instruments.
