Problems solved by technology
[0002] As we all know, when the temperature sensor is tested at the factory, the resistance of the two wires of the temperature sensor is usually detected with four pens of a four-wire multimeter. The disadvantage is that during the detection process, the contact is unstable because there is no positioning device , slow detection speed and low work efficiency
