Clampmittauksella

Clampmittauksella, often translated as clamp measurement or clamp meter measurement, refers to a method of electrical measurement using a clamp meter. A clamp meter is a versatile electrical testing instrument that combines a basic digital multimeter with a current sensor. The primary distinguishing feature of a clamp meter is its hinged jaw, which can be opened and clamped around a conductor, such as an electrical wire or cable.

This clamp mechanism allows for non-invasive current measurement. Instead of needing to break the circuit to insert an ammeter in series, the clamp meter measures the magnetic field produced by the current flowing through the conductor. By analyzing the strength of this magnetic field, the clamp meter can accurately determine the current's magnitude without direct contact with the electrical flow.

Beyond current measurement, most clamp meters also offer functionality for measuring voltage, resistance, and continuity, similar to a standard multimeter. This makes them a popular tool for electricians, technicians, and DIY enthusiasts for a wide range of troubleshooting and diagnostic tasks. The ability to measure current without disrupting the circuit is particularly advantageous for safety and convenience in many electrical applications.
