Specification
1625, Fluke Earth Tester
Digital Earth Tester
Basic Features
• 3- and 4-Pole Fall of Potential – standard earth ground testing using two ground stakes
• Selective testing – without disconnecting ground rods, a technician can measure ground resistance using a combination of stakes and a clamp.
• Stakeless testing – innovative solution using only clamps, instead of ground stakes, to measure earth ground loop resistance.
• Automatic Frequency Control ( AFC) – identifies existing interference and chooses a measurement frequency to minimize its effect, providing a more accurate earth ground value.
• R* measurement – calculates earth ground impedance at 55 Hz to more accurately reflect the earth ground resistance that a fault-to-earth ground would see.
• Adjustable limits – for quick test result verification.
