Detailed Product Overview

The CM4141-90 AC Clamp Multimeter is a convenient bundle consisting of the CM4141-50 and the Z3210 Bluetooth Adapter. It is designed for technicians working in power distribution and utility companies. Unlike most clamp multimeters, it measures only AC current, with 3 dedicated ranges of 60 A, 600 A, and 2000 A. This focus on AC currents reflects the needs of the utility industry, where DC measurements are rarely required, and allows for a more costeffective instrument without compromising safety or reliability.

Drawing on HIOKI’s decades of experience in high-precision current sensing, the CM4141-90 features very slim jaws designed for conductors up to 55 mm in diameter, making it easy to clamp even in crowded switchgear or distribution panels.

More than just a clamp meter 

In addition to AC current and voltage measurement up to 1000 V AC/DC, the CM4141-90 includes key multimeter functions such as resistance, continuity, diode testing, and inrush measurement. Automatic AC/DC detection, Max/Min/Avg, PEAK values, and manual/auto hold functions simplify daily operation. With the included Z3210 Bluetooth adapter, measurement data can be transferred directly to the GENNECT Cross app on iOS or Android smart devices for easy wireless logging and reporting. The app also enables harmonic analysis from 1st to 30th order for extended diagnostic capability.

Safety is ensured with CAT IV 600 V / CAT III 1000 V ratings. Like all HIOKI instruments, the CM4141-90 is manufactured in Japan to the highest standards of accuracy, safety, and longterm reliability.
