As for thermocouples and thermal resistance, what is the indication value of the instrument in the following conditions?
What happens if the polarity of the compensating wire is reversed when the correct thermocouple is used to correct the cold end of the thermocouple?
Thermal resistance, open circuit, short circuit or thermal resistance use two wire system: thermal resistance open circuit, display full scale (or infinity), short circuit shows zero, use two wire system display is big
When the thermocouple open circuit, short circuit or polarity reverse: the thermocouple open circuit shows zero, the short circuit shows zero, the polarity of the reverse display is too small
