Detailed Product Overview
The CM4375-50 Clamp Multimeter is designed for professionals who often work in tight spaces and need precise AC/DC current measurement. With a wide 1000 A range and True RMS accuracy, it is ideal for industrial power distribution, heavy machinery, and EV charging systems. Drawing on decades of HIOKI expertise in current sensing, its super slim 34 mm jaws allow users to clamp conductors even in confined spaces, allowing safe and reliable measurements where conventional clamp meters don’t fit.

Drawing on decades of HIOKI expertise in current sensing, its super slim 34 mm jaws allow users to clamp conductors even in confined spaces, allowing safe and reliable measurements where conventional clamp meters don’t fit.
Voltage measurement up to 1000 V AC/DC covers most applications. When paired with the
optional P2010 High Voltage Divider, the measurement range extends up to 2000 V DC in
CAT III environments, making the instrument suitable for safe testing of photovoltaic strings
and high-voltage batteries. True RMS technology guarantees accurate results even with
distorted waveforms.
Versatile multimeter functions
In addition to current and voltage, the CM4375-50 offers multimeter functions such as
resistance, capacitance, continuity, diode polarity check, and inrush measurement. Automatic
AC/DC detection and advanced display options (Max/Min/Avg, PEAK values, filter function,
manual/auto hold, pass/fail judgement) simplify daily tasks and save time. The included L9300 test leads feature a slide-type mechanism that allows the metal tips to be extended or
retracted, eliminating removable caps and simplifying handling, and enables a safe switch
between short tips for higher CAT ratings and fully extended tips for tight measurement
points.
Bluetooth and safety ratings
When combined with the optional 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.
The CM4375-50 complies with CAT IV 600 V / CAT III 1000 V, and with the P2010 it also
supports CAT III 2000 V. Its rugged housing is rated IP54 for dust and splash resistance,
ensuring safe operation on construction sites and in harsh outdoor conditions. Like all HIOKI
instruments, the CM4375-50 is designed and manufactured at HIOKI’s own factories in
Japan, ensuring accurate performance, safety, and long-term reliability
