The M266 Digital Clamp Meter is a multi-functional electrical measuring instrument designed for professionals, students, and hobbyists who work with electricity. It provides an efficient and safe way to measure high AC currents without disconnecting wires, thanks to its clamp jaw design. By clamping around a conductor, the meter measures current instantly and eliminates the need to cut or strip cables, making it safer and faster than traditional multimeters.
The M266 offers a wide measurement range, including AC current up to 1000A, AC voltage up to 750V, DC voltage up to 1000V, and resistance up to 200 kΩ. In addition to current and voltage measurements, the meter can perform continuity checks, diode tests, and resistance measurements, making it a versatile all-in-one device.
Its large digital LCD display ensures readings are clear and easy to understand, even in low-light conditions. The data hold function allows users to freeze readings on the screen, which is helpful when working in tight or complex environments. The meter also features overload protection to ensure user safety during high-voltage or high-current testing.
With its rugged outer casing and compact design, the M266 Clamp Meter is built to withstand frequent use in fieldwork, workshops, and industrial environments. It is also lightweight and portable, so electricians and engineers can easily carry it for on-site troubleshooting.
Whether you are testing household circuits, maintaining industrial machines, or studying electrical systems in an educational lab, the M266 is an essential measuring tool. It combines the reliability of a digital multimeter with the convenience of a clamp meter, making it a go-to device for accurate and safe electrical measurements.
