Reasons for the low temperature display of the muffle furnace

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;

messen:

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

2. Check the electrode and wiring connection;

3. Ersetzen Sie das Thermoelement;

4. Adjust the measurement position;

5. Replace the compensation wire;

6. Connect the compensation wire correctly;

7. Replace the compensation wire;
