Fluke 1623-2 KIT provides the instrument and accessories for three- and four-pole, selective and stakeless earth testing. It includes a Fluke 1623-2, two clamps, four earth stakes, three cable reels, a USB cable and a C1620 carrying case. Results are stored in instrument memory and transferred over USB. Stakeless testing requires a closed loop with multiple earth paths; an isolated single electrode requires the fall-of-potential method.
