In what direction will the null meter pointer on the model 3604 thermo unit deflect if the temperature well heat is greater than the set point?

• A. To the left
• B. To the right
• C. It will not move
• D. It will oscillate

Answer: (B)

When the temperature well heat exceeds the set point on the model 3604 thermo unit, the null meter pointer deflects to the right. This rightward movement indicates that the measured temperature is higher than the desired set point, reflecting an active response to the increase in temperature. In calibration and measurement processes, the null meter is designed to indicate the difference between the set point and current measurements. Consequently, a higher measured temperature would result in a positive deflection, visually providing feedback to the technician or operator that corrective actions might be necessary to reach the desired conditions. This behavior is typical in systems that utilize null meters for thermal readings and aligns with the expected outcomes in calibration practice.
