variable name meaning in arduino library - variables

Question

Can someone help me here to understand about arduino library variable name like what is tempTC, tempCJC, faultOpen, faultShortGND, faultShortVCC,
I am so confused. please help here ! thanks

Serial.print(tempTC);
Serial.print("\t");
Serial.print(tempCJC);
Serial.print("\t");
Serial.print(faultOpen);
Serial.print(faultShortGND);
Serial.println(faultShortVCC);
digitalWrite(LED, HIGH);
delay(500);
digitalWrite(LED, LOW);
delay(500);

Answer 1

tempTC: The thermocouple value read from the IC.
tempCJC: The Cold Junction-Compensated temperature value.
faultOpen faultShortGND faultShortVCC: Flags that indicate wether any of these faults occurred while reading the temperature.
All these are done directly in the MAX31855 IC, read via SPI with the library you posted.
