Applications
• Measure electrical ground rod and
grid resistance
• Use on multi-grounded systems
without disconnecting the ground rod
under test
• Measure resistance and continuity
of grounding loops around pads
and buildings
• Measure leakage current flowing
to ground or circulating in ground
systems
• Conduct field surveys and retrieve
and analyze readings at a later time
• Use on cell towers and
telecommunication sites
• Use on pools, spas and other
consumer installations
