TENMA True RMS AC/DC Digital Clamp Meter - 400A

The TENMA True RMS AC/DC Digital Clamp Meter is a versatile and highly capable diagnostic tool, engineered for precision in a wide range of electrical and electronic applications. Its true RMS (Root Mean Square) technology ensures accurate readings of non-linear AC waveforms, making it indispensable for professional electricians, engineers, and advanced DIY enthusiasts who require reliable measurements on modern equipment.

This meter excels in functionality, featuring a clear LCD display with a convenient backlight for low-light conditions. Key operational functions include Max/Min recording to capture peak values and a data hold feature for stabilising and noting readings safely. It is equipped with essential testing modes such as diode check and continuity testing with an audible buzzer, alongside comprehensive measurement capabilities for AC/DC current (clamp-on), AC/DC voltage, resistance, capacitance, frequency, and temperature.

Designed with user convenience in mind, it incorporates an integrated flashlight to illuminate dim work areas and an automatic power-off function to conserve battery life after 15 minutes of inactivity. Power is supplied by three included AAA batteries, and the complete kit comes with a protective carry case for secure transport and storage, alongside a detailed manual.

With a robust jaw design capable of opening up to 30mm, it can easily clamp around conductors for non-intrusive current measurement. Its compact dimensions and ergonomic form factor make it a portable and essential addition to any toolkit, built to TENMA's standards for quality and performance in professional test equipment.
