EXTECH 380942 : 30A True RMS AC/DC Mini Clamp Meter ยี่ห้อ Extech, USA
Highest resolution (0.1mA) and accuracy at low currents
The compact Extech 380942 is a 30 Amp mini AC/DC clamp meter. The clamp meter has a remarkable 0.1mA resolution (AC), very low-current sensitivity, and a small diameter jaw designed to reach into small areas. The 30 Amp range with 0.1mA (AC) and 1mA (DC) resolution is optimized for finding problems where very low current variances would be missed by standard clamp meters. This mini clamp meter is useful for troubleshooting tasks in plant maintenance, electrical, HVAC, and telecom work, as well as residential electrical, fleet maintenance, marine, and motorcycle repairs. This CAT III-rated True RMS mini clamp meter comes with test leads, 2 AAA batteries, soft carrying case, and user 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)
