Which document or guideline deals with putting measuring devices into service?

The document that deals with putting measuring devices into service is HB 44. This document, published by the National Conference on Weights and Measures (NCWM), serves as a foundational standard in the field of measurements. HB 44 provides specifications, tolerances, and other technical requirements for various types of measuring devices, ensuring they operate accurately and reliably in commercial applications.

When it comes to putting measuring devices into service, HB 44 outlines the necessary procedures and requirements that must be met before a device can be used for legal transactions. These guidelines ensure that devices are installed correctly, calibrated appropriately, and maintained according to established standards, thereby promoting fairness and accuracy in trade.

Other documents mentioned, such as Document S-3, Field Manual 102, and Guideline 7A, provide relevant information and practices related to measurement and testing, but they do not specifically address the detailed requirements and processes for putting measuring devices into service in the same comprehensive manner as HB 44. This focus makes HB 44 the correct reference in this context.
