What is the primary purpose of using a clamp on ammeter?

To measure voltage
To measure current
To measure resistance
To test battery capacity

The correct answer is: To measure current

A clamp-on ammeter is specifically designed to measure electrical current flowing through a conductor without the need to make direct contact with the circuit or disconnect it. The tool uses a current transformer and can handle both alternating current (AC) and direct current (DC) measurements, depending on the model. This feature allows technicians to efficiently monitor current levels in RVs and other electrical systems, making it invaluable for diagnosing issues or ensuring that systems are operating within their intended specifications. In contrast, measuring voltage requires direct contact with the circuit leads, and resistance measurements typically involve breaking the circuit. Testing battery capacity usually involves more specialized equipment designed for that specific purpose, rather than a clamp-on ammeter. Hence, the primary function of a clamp-on ammeter is to provide accurate current measurements, reinforcing its vital role in electrical diagnostics and maintenance.
