The 380947 is a True RMS DC/AC mini clamp meter designed for accurate low current measurements in tight spaces. It features a large 4000 count LCD display with full function indication, a fast 40 segment analog bargraph, and one-touch "Auto Zero" for DC current measurements. The meter offers multi-range AC current measurement up to 400A with resolutions from 1mA to 100mA, and DC current measurement up to 400A with resolutions from 10mA to 100mA, all with ±(1.5% +3d) accuracy for AC and ±(1.0% +2d) for DC. Additional features include frequency measurement capability up to 10kHz with ±(0.5% +2d) accuracy, data hold and Max/Min recall functions, a 0.9" (23mm) clamp jaw opening, and overload protection to 400A DC. The compact design (183×64×36mm, 190g) makes it ideal for energy usage audits and troubleshooting in confined areas where traditional clamp meters cannot fit.
