Extech 380940 400A True RMS AC/DC Clamp Meter Details
The Extech 380940 is a unique clamp testing device that can be used to carry out multiple measurement types.
Although small in size and lightweight, this tester is still packed full of functionality. The main testing procedures the Extech 380940 can perform including AC/DC power evaluations, AC/DC current evaluation, AC/DC voltage calculations and frequency calculations. Results are expressed both via a numerical readings and also as a fast 40 segment analogue bargraph on the devices' LCD screen (4000 count).
When carrying out AC voltage and current measurements the 380940 uses true-RMS technology to ensure measurements accuracy at all times. The device will also power down when left idle for an extended time period and can features jaw opening of 0.9" (23mm).
This clamp testing device is EN 61010-1 compliant and CAT II 600V safety rated.
