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.

The Fluke 1623 is the stand-alone unit
