What is the purpose of special tests in liquid measuring devices?

The purpose of special tests in liquid measuring devices primarily focuses on developing the operating characteristics of the device. These tests help in understanding how the device performs under various conditions and determine its accuracy, reliability, and functionality. By conducting special tests, one can identify the nuances in performance and ensure that the device meets the required standards and specifications.

For instance, special tests might include evaluating the device's response to different flow rates, temperatures, or fluids, which in turn helps adjust and improve its design and operation. Understanding these operating characteristics is crucial for proper usage and can lead to better maintenance practices, ultimately ensuring the device measures accurately over its lifespan.

While calibration, quality control, and environmental assessments are important aspects of overall device maintenance and regulation, their primary focus differs from the foundational goal of establishing a device's operating characteristics through special testing.
