Determine methods: with a table with three "buzz off" block measuring thermocouple positive and negative, such as No beeps, then the thermocouple bad.

Judgment: in a three-table "beep on off" block measuring thermocouple positive and negative, in the absence of beeps, the thermocouple.

Judgment method: “The buzzing make-and-break” keeps off the survey thermo-element positively and negatively with the volt extremely, if non-buzzing sound, then the thermo-element is bad.

Method 3: Use a form "buzzers" block off thermocouples polarity measurements, if there is no beep, the thermocouples bad.

Judgment: in a three-table "beep on off" block measuring thermocouple positive and negative, in the absence of beeps, the thermocouple.
