What should I do if the detection instrument of platinum rhodium thermocouple shows zero time

Remove the thermocouple from the input end of the instrument thermocouple and short-circuit the input end of the instrument thermocouple with any wire. When powered on, if the display value of the digital tube on the instrument is about room temperature, it indicates that the external connection of the thermocouple is open, and the same example thermocouple should be replaced. If the above state persists, it indicates that the input end of the instrument was damaged during transportation and needs to be replaced.

Remove the thermocouple from the faulty instrument mentioned above and replace it with a thermocouple connected to a nearby instrument with the same calibration number that is malfunctioning. After powering on, if the digital display on the upper row of the faulty instrument shows a fever, explain that the external connection of the thermocouple is open and replace it with a thermocouple of the same type. If the above state persists, it indicates that the input end of the instrument was damaged during transportation and needs to be replaced.

Remove the faulty thermocouple from the instrument, use a multimeter to measure ohms (R) * 1, and use two multimeter sticks to measure the two ends of the thermocouple. If the resistance value displayed on the multimeter is very high, it indicates that the external connection of the thermocouple is open, and replace it with the same example thermocouple. Otherwise, if there is a certain resistance value, it indicates that the input terminal of the instrument has a performance, and the instrument should be replaced.

The above are the handling measures for the detection instrument of platinum rhodium thermocouple showing zero time. We hope it may assist everyone in handling the results.
