What are test instruments primarily used for in Inspection and Testing?

Test instruments are primarily utilized to measure electrical properties, which is essential for ensuring the performance, safety, and compliance of electrical installations. These instruments can assess various parameters such as voltage, current, resistance, and continuity. Accurate measurements are crucial during inspections and testing processes to verify that electrical systems operate correctly and within designated specifications, thus preventing potential hazards and ensuring maintenance of system integrity.

While creating electrical installations is an important aspect of electrical work, it is not the primary function of test instruments. Similarly, the generation of electricity is a process related to electrical power generation, not the function of measurement or testing devices. Monitoring environmental conditions, while relevant in certain contexts, is also not the main purpose of test instruments specifically designed for electrical inspections and testing. So, the emphasis on measuring electrical properties highlights the fundamental role that these instruments play in maintaining safe and efficient electrical systems.
