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

•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)
Ideal for low current measurements
Extech’s Mini Clamp Meters, with their high resolution, are the ideal tools for
accurately measuring very low AC & DC currents. Smaller in size than traditional
clamp meters, they easily fit into tight spaces.
