Description
The PROVA-400 AC/DC 400A Watt Clamp Meter is a versatile electrical measurement tool built for technicians who need reliable power and current analysis in the field. It supports AC and DC power measurement up to 240 kW, along with True RMS AC current and voltage, ensuring accurate readings even with non-linear loads. The compact 23 mm conductor jaw allows easy access in crowded cable bundles and switch boxes, making the meter suitable for maintenance, troubleshooting, and energy monitoring tasks.
In addition, the meter features a large 3¾-digit LCD with a 40-segment bargraph that updates up to 30 times per second, enabling quick observation of fluctuating signals. Users can quickly zero the DCA measurement, capture readings using Max/Min and Data Hold, and rely on automatic power-off to conserve battery life. With a single rotary selector, manual range selection, and robust overload protection, the PROVA-400 delivers dependable performance for electrical professionals working in demanding environments.
