4610 4-Point Ground Resistance Testers

The Digital Ground Resistance Tester 4610 performs ground resistance and soil resistivity tests. This direct reading tester measures from 10MO to 1999O, and is auto-ranging, so it automatically seeks the optimum measurement range. The Model 4610 is easy to use - simply connect the leads, press to measure, and read.

The large LCD (nearly 3/4" high) also indicates low battery status, overrange, and test lead shorts and lead reversals. Three LED indicators on the front panel continuously warn user of measurement problems to ensure accurate and reliable tests.

Features
-Fall-of-Potential method
-Measures ground resistance (2- and 3-Point) and soil resistivity (4-Point)
-Step voltage tests and touch potential measurements
-Auto-Ranging: automatically selects the optimum range
-Designed to reject high levels of noise and interference
-Extremely simple to operate: connect - press - read
-LED on faceplate informs operator of high input noise, high auxiliary rod resistance and fault connections
-Battery powered
-Rugged dustproof and rainproof field case
-May be used for continuity tests on bonding
-Color-coded terminals

Applications
-The Model 4610 may be used to perform the following tests:
-Three-point measurements of resistance to ground of ground rods and grids.
-Four-point tests or soil-resistivity measurements.
-Touch potential measurements (an alternative to three-point tests in evaluating electrical safety).
-Two-point tests for continuity on bonding or on pre-established grounds.
