Extech 380947, 380941 Data Sheet
Product DATASHEET
Mini DC/AC Clamp Meters
Common 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)
CAT III - 300V
