Кантип сапатына баа берүү керек жогорку температурага туруктуу меш thermocouple?

1. Visually observe whether the protective tube is corroded and penetrated, whether it is leaking, etc.

2. Use a multimeter to measure the continuity. The resistance of the assembled thermocouple is generally not more than 2 ohms, and the resistance of the network cable is generally not more than 50 ohms. Generally, it can be determined that it is broken if it is greater than 1K.

3. Measure the resistance value with a multimeter. If the resistance exceeds 100K, it is bad.

4. Use the multimeter ohm measurement method to measure, adjust the resistance, connect the two ends, and burn it with a lighter. If the pointer of the multimeter is obviously larger or smaller, it means it is good. If the pointer does not move, it means it is broken.

5. Use a multimeter to measure the voltage at both ends in the millivolt range. If there is no voltage, it will be broken.
