Fluke SaturnGeo X Advanced Three and Four Pole Earth Ground Tester
The Saturn Geo X Earth Ground Tester is ideal for measurement of ground resistance using the classic fall of potential test, as well as the ‘selective’ and ‘stakeless’ test. The ‘selective’ method does not require the electrode under test to be disconnected before measurement, unlike other methods. The ‘stakeless’ method is quick and simple and replaces stakes with current transformers (probes) that are clamped around the ground conductor under test. Both techniques make it faster and safer to test.
Earth ground resistance and resistivity should be measured when:

• Installing new ground system and electrical equipment
• Periodically testing ground and lightning protection rods
• Prior to design of ground protection systems
• Installing distribution equipment – transformers, switchgear etc.
• Conventional three and four pole earth ground testing
• Innovative selective and stakeless techniques for fast and safe measurement without disconnection
• Two-pole ac resistance measurement
• Four- and two-pole dc resistance measurement
• One button measurement – automatic hold of last set of measurements
• Limit for verification of measurements
• Automatic frequency control (AFC) for stable measurements
• R* measurements at 55Hz for impedance in electricity distribution systems
• Rugged housing rated to IP56
• Full range of accessories for conventional and clamp testing
• 2-Year warranty
