The Fluke 1623 is perfect for performing predictive maintenance checks of commerical and industrial applications.
The Fluke 1623 is an all-in-one earth ground tester, offering 'one-button' simplicity. Not only measure
ground resistance using the classic 'fall of potential test' but also
enable time saving testing using the 'selective' and 'stakeless'
methods. 'Selective' testing does not require the electrode under test
to be disconnected during the measurement, thus increasing safety. The
simple 'stakeless' method quickly checks ground connections using two
current transformers (probes) clamped around the ground conductor under
test.
Testing Methods
3- and 4-Pole Fall of Potential – standard earth ground testing using two ground stakes
4-Pole Soil Resistivity testing – determine soil resistivity using four 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.
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.
