ACI Certification Practice Exam

When should the temperature sensor be removed after reading?

1. It should be removed immediately

2. It should be left in place until all readings are complete

3. It can be removed at any time

4. It should be removed only after verifying accuracy

The correct answer is: It should be left in place until all readings are complete

The correct approach is to leave the temperature sensor in place until all readings are complete. This ensures that the data collected is consistent and reliable throughout the entire measurement process. Removing the sensor prematurely could lead to gaps in data or inconsistencies, which could compromise the accuracy of the results. In scenarios where temperature readings are crucial—such as in material testing or environmental monitoring—maintaining the sensor in place allows for an accurate assessment of conditions over the entire period of interest. This practice also enhances the repeatability of measurements, as any subsequent readings can be directly compared to prior data collected under the same conditions. While other options suggest different practices, they fail to account for the necessity of a thorough and consistent data collection protocol, which is vital in ensuring the integrity of the evaluation process.
