For both indoor and outdoor earth resistance testing, the IP56-rated Fluke 1623-2 GEO Earth Resistance Tester is ideal. The 1623 impresses with its dependable performance and usability, offering a large internal memory and high accuracy. This tester is capable of conducting 3/4 pole fall-of-potential earth resistance testing, 4 pole soil resistivity testing, and stakeless and selective earth ground rod testing. Each test mode's acquired data can be directly kept on the inbuilt memory (up to 1500 records maximum) or exported via USB to a PC for additional analysis or long-term storage. As was already noted, this model has several important quality of life features and is very user-friendly. In order to guarantee that the right connections are made, this model automatically prompts the user for the necessary stakes or clamps for each of the four test types—4 pole fall of potential, 4 pole soil resistivity, selective or stakeless testing. Test data is shown in real time on the huge 4-digit LCD, and the large rotary dial is very simple to operate with gloves on. In conclusion, the unique stakeless testing feature of this earth resistance tester is a product highlight. It is an incredibly useful tool with remarkable accuracy and functionality.
