Reasons for the low temperature display of the muffle furnace

1. The temperature of the reference terminal of the thermocouple is too high;

2. Leakage of thermocouple electrode;

3. Deterioration of thermocouple electrode;

4. The measuring position of the thermocouple is too far;

5. The compensation wire does not match the thermocouple;

6. The polarity of the compensation wire and the thermocouple is reversed;

7. Compensation wire insulation is reduced;

đo lường:

1. Check the temperature of the reference terminal and it should meet the requirements;

2. Check the electrode and wiring connection;

3. Thay cặp nhiệt điện;

4. Adjust the measurement position;

5. Replace the compensation wire;

6. Connect the compensation wire correctly;

7. Replace the compensation wire;
