Mini DC/AC Clamp Meters 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. Features: • Three models provide high Accuracy and Resolution 380942 • 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 380941 • 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) 380947 Specifications True RMS AC Current: Resolution Accuracy DC Current: Resolution Accuracy AC Voltage: Resolution Accuracy DC Voltage: Resolution Accuracy Resistance: Resolution Accuracy Frequency: Resolution Accuracy Dimensions: Weight: 380942 True RMS 30A 0.1mA ±(2.0%+5d)@50/60Hz 30A 1mA — 400V 0.1V ±(2.0%+5d) 400V 0.1V ±(1.0%+2d) — — 7.2x2.5x1.4" (183x64x36mm) 6.2 oz (190g) 380941 — 200A 100mA ±(1.0% +2d) 40A 10mA ±(1.0% +2d) 400V 0.1V ±(1.5% +4d) (50/60Hz) 400V 0.1V ±(1.0% +2d) 400Ω 0.1Ω ±(1.5% +2d) 10kHz 0.01Hz ±(0.5% +2d) 7x1.75x1.25" (178x45x32mm) 6 oz (170g) 380947 True RMS 4A/40A/100A/400A 1mA/10mA/100mA/100mA ±(1.5% +3d) 40A/400A 10mA/100mA ±(1.0% +2d) — — — 10kHz 0.01Hz ±(0.5% +2d) 7.2x2.5x1.4" (183x64x36mm) 6.2 oz (190g) Ordering Information 380942..............True RMS 30A Mini Clamp Meter 380942-NIST ....380942 with Certificate of Calibration Traceable to NIST 380941..............200 Amp DC/AC Mini Clamp DMM 380941-NIST ....380941 with Certificate of Calibration Traceable to NIST 380947..............True RMS DC/AC Mini Clamp Meter 380947-NIST ....380947 with Certificate of Calibration Traceable to NIST Accessories 480172..............AC Line Separator - 3 prong www.extech.com Specifications subject to change without notice. 1/26/12 - R1 Copyright © 2007-2011 Extech Instruments Corporation.
