?What is the primary function of a multimeter in electrical testing

The primary function of a multimeter in electrical testing is to measure various electrical parameters such as voltage, current, and resistance. It is a versatile tool that can be used for diagnosing electrical problems, testing circuits, and ensuring components are functioning correctly. By providing accurate readings, a multimeter helps electricians and technicians troubleshoot and repair electrical systems efficiently.

?How does an insulation resistance tester ensure the safety of electrical systems

An insulation resistance tester ensures the safety of electrical systems by measuring the resistance of the insulating material around conductors. High insulation resistance indicates good insulation quality, preventing leakage currents that could lead to electrical shocks, short circuits, or equipment failure. By regularly testing insulation resistance, maintenance personnel can identify deteriorating insulation and take corrective actions before major issues arise, ensuring the system's reliability and safety.
