When should you check the zero balance indication during an inspection?

Checking the zero balance indication both before and after the test, as well as after removing test loads, is essential for ensuring accurate measurements and reliable data. The zero balance indicates whether the scale is calibrated correctly and can provide accurate readings. By checking it before the test, you confirm that the scale is starting at a true zero point, which is crucial for the integrity of the test results.

After the test, checking the zero balance verifies that the scale remains accurate and has not drifted due to environmental factors or mechanical issues. Additionally, checking again after removing test loads ensures that the scale returns to zero, which can help in identifying any discrepancies that may arise during the testing process. This comprehensive checking process helps maintain high standards of accuracy and reliability in weight measurement, which is vital in licensing and regulatory contexts.
