Product Overview

The FLUKE-1621 CAL D is a basic earth ground tester for resistance measurement. This easy to use tester is used for measurement of 3-pole earth ground resistance, 2-pole AC resistance of a conductor and interference voltage. It has resistance measuring range from 0.15 to 20 ohm (0.01ohm resolution), 200 ohm (0.1ohm), 2Kohm (1 ohm). The unit features basic ground testing methods including 3-pole fall of potential earth testing for basic measurements as well as 2 pole ground resistance tests for added versatility. It's convenient size, rugged holster and large, clear LCD display make it an ideal field earth ground tester for most electrical grounding work environments. With a simple user interface and intuitive functionality, the Fluke 1621 is a handy grounding tool for electrical contractors, utility test engineers and earth ground specialists. Voltages between jacks H/C2 and E/C1 is 250Veff maximum and between jacks S/P2 and E/C1 is 250Veff maximum.
