The Extech 380941 is a miniature-sized clamp meter that’s designed for being clamped onto very small applications, or applications that may be difficult to reach with larger testers.
It features 0.9″ (23mm) jaw opening and can be used to measure AC current to 200A and DC current up to 40A. It can also be used to carry out AC and DC voltage measurements up to 400V, resistance measurements to 400Ω and frequency measurements to 10kHz.
The data hold function freezes the displayed reading for convenient recording, while the relative mode allows users to zero out the initial measurement for more accurate relative readings.
