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 AA 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
• Measure current draw when conducting energy usage audits
• 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)
