The nVent GARDNER BENDER DSA540A Snap-Around Digital Clamp Meter is an essential tool for professional electricians and maintenance technicians requiring precise, non-contact current measurements. This 10-function, 26-range, auto-ranging unit is engineered to measure up to 400A AC/DC current and 600V AC/DC voltage without the need to break the circuit or contact live conductors, ensuring a safer testing environment. In addition to current and voltage, the DSA540A measures resistance up to 40 Mohms, frequency, and capacitance, while providing reliable diode and continuity testing. The integrated audible beeper and bright LED visual indication permit easy identification during fast-paced troubleshooting. To ensure accuracy and ease of use, the meter features data hold and relative measurement capability to maintain the reading on the liquid crystal display, even after the clamp is removed from the conductor. Efficiency is built-in with an auto power-off functionality to save battery life and a low battery indicator to ensure you never get caught with inaccurate data. The compact, lightweight design allows the unit to fit comfortably into any tool belt or small workspace, while the included carrying case keeps the instrument clean and protected between jobs. Safety-tested and certified to cETLus with CAT II 600V and CAT III 300V ratings, the DSA540A delivers the reliability and performance needed for demanding Industrial and Scientific electrical testing environments.
