Test Kit descriptions on next page
FEATURES
• Measures soil resistivity (4-Point)
• Measures ground resistance (2- and
3-Point) Fall-of-Potential method
• Step voltage tests and touch potential
measurements
• Auto-Ranging: automatically selects
the optimum resistance range and
test current
• Designed to reject high levels of noise
and interference
• Extremely simple to operate:
connect - press - hold - read
• LED on faceplate informs operator
of high input noise, high auxiliary rod
resistance and fault connections
•Large easy-to-read backlit display
• Battery powered (Model 4620)
• AC powered with rechargeable NiMH
battery pack (Model 4630)
• Rugged dustproof and rainproof
field case
• Can also be used for continuity tests
on bonding
•Color-coded terminals
