Advanced Earth Ground Tester, Measuring voltage: 20/48V ac, Short circuit current: 250mA ac, Measure frequency: 94, 105, 111,128 Hz

The Fluke 1625 is a distinctive earth ground tester that can perform all four types of earth ground measurement.

It is able to measure earth ground loop resistances using only clamps – called stakeless testing. This method doesn’t require the use of earth ground stakes or the disconnection of ground rods.

Testing methods:

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

The Fluke 1625 offers these advanced features:

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
