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)

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.
