AC/DC CLAMP METER CM4376 (Bluetooth®)
Easily Get Into Tight Spaces
Innovative Jaw Provides Remarkable Accessibility
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM4376 is a 1000A AC/DC True RMS clamp meter that features a uniquely designed slim jaw that lets you easily get into the narrow gaps between cables in crowded electrical distribution boxes without fear of damaging the cables or the clamp meter. The broad -25°C to 65°C operating temperature range and IP54 dustproof and waterproof enclosure to enable professionals to work quickly in challenging situations including the development, repair, and maintenance of equipment and devices such as electric vehicles. Additionally, the high-voltage DC measurement capability of up to 1700 V (*1) is ideal for the clamp maintenance inspections of electrical and solar power equipment. Finally, built-in Bluetooth wireless technology lets you send measured values to a smartphone or tablet, display waveforms in real time, and create reports right on site.
CAT IV 600 V, CAT III 1000 V
Made for Real-World Situations Uncompromising Design
Panel overcrowding is commonly found in many power distribution breakers and termination boxes. The newly designed thin sensor gets into even the most limited spaces. Eliminate the issues of trying to find the right wire or forcing the clamp around thick cables.
Key Features
- Easily get into tight spaces between cables thanks to thin sensor structure
- Measure DC voltages of up to 1700 V (*1) for open voltage inspections of solar panels
- Simultaneously measure inrush current in RMS and crest values
- Measure up to 1000 A
- Automatic AC/DC function helps boost work efficiency
- Expanded -25°C to 65°C operating temperature range
- Send measured values to a smartphone or tablet using Bluetooth® wireless technology (CM4376)
- *1:Your instrument can be used to measure voltages in excess of 1000 V DC if and only if both of the following conditions are satisfied:
- 1. The circuit under measurement is isolated from the commercial power grid.
- 2. The circuit under measurement is isolated from ground.
- e.g.: When measuring the no-load voltage of an ungrounded PV panel
- Do not use the instrument with circuits whose terminal-to-ground voltage exceeds 1000V. Doing so may result in electric shock.

Data can be downloaded to tablets and smartphones using Hioki’s dedicated free app "GENNECT Cross," available from the Google Play or App Store.
Instantly create reports by a free app (GENNECT Cross)
GENNECT Cross, a free app designed specifically for use with Hioki measuring instruments, lets you check and manage measurement results and create reports.
The software provides a range of functionality that helps manage data in the field, including photographing measurement sites, placing measurement results on photographs, and saving hand written memos.
Damage-resistant jaws! Guaranteed for 30,000 open-close cycles
The new and improved design features stronger jaws (the current sensor portion of the instrument) and a dramatic boost in the duration of the warranty from 10,000 to 30,000 open-close cycles to ensure the instrument will provide even more years of reliable use. The CM4375, CM4376, CM4141 and CM4142 deliver the dual functionality of ease of clamping and resistance to damage.
Inrush (Rush current): Assess transient currents at motor startup
The CM4000 Series can simultaneously measure inrush current in RMS as well as maximum crest values at motor startup and for welding currents.
The clamp meters automatically detect the duration of the inrush current (which can range from several dozen milliseconds to several hundred milliseconds) and measure the current during that interval, enabling them to yield more accurate
measurements than standard clamp-on meters whose measurement interval is fixed to 100 ms.
