380947: 400A True RMS AC/DC Mini Clamp Meter ยี่ห้อ Extech, USA

True RMS mini-clamp with high current resolution

The compact Extech 380947 is a 400 Amp True RMS mini clamp meter. This meter has a small diameter jaw designed to reach in small areas while providing 1mA resolution and very low-current sensitivity. This mini clamp meter is useful for current and frequency related troubleshooting in plant maintenance, electrical, HVAC, and telecom work, as well as home electrical, fleet maintenance, marine, and motorcycle repairs. Comes with battery and manual.

Features:

Three models provide high Accuracy and Resolution
Large 4000 count LCD display with full function indication
Fast 40 segment analog bargraph
One touch “Auto Zero” for DCA measurements eliminates the need to turn a knob to zero adjust
Data hold, Max/Min recall display
0.9″ (23mm) clamp jaw opening
Overload protection to 400A DC
True RMS models recommended for measurements where distortion may otherwise cause inaccuracies
Optional 3-prong AC Line Separator enables safe and easy measurements on power cables with molded plugs (splits hot conductor from neutral and ground)
