1620-2 Series
Earth Ground Testers GEO
The new Fluke 1620-2 series offer data storage
and download capabilities via USB port, have a
new large display and world class accessories
will simplify and speed up testing time.
These unique earth ground testers that
can perform all four types of earth ground
measurement:
• 3- and 4-Pole Fall-of-Potential (using stakes)
• 4-Pole Soil Resistivity testing (using stakes)
• Selective testing (using 1 clamp and stakes)
• Stakeless testing (using 2 clamps only)
Plus:
• IP56 rated for outdoor use
• Professional carrying case
• USB data storage and transfer
In addition, the Fluke 1625-2 offers these
advanced features:
• Automatic Frequency Control (AFC) -identifi
es existing interference and chooses a
measurement frequency to minimize its
effect, providing more accurate earth ground
value
• R* measurement – calculates earth ground
impedance at 55 Hz to more accurately
refl ect the earth ground resistance that a
faulttoearth ground would see
• Adjustable limits – for quicker testing
Earth ground resistance and soil
resistivity should be measured when:
• Designing earth ground systems
• Installing new ground system and electrical
equipment
• Periodically testing ground and lightning
protection systems
• Installing large electrical equipment such as
transformers, switchgears, machines, etc.
