The Digital Ground Resistance Tester Model 4630 performs ground resistance
and soil resistivity tests. This direct reading testers measures from 0 to
2000 Ohms, and is auto-ranging, so it automatically seeks outs the optimum
measurement range. The Model 4630 is rugged, easy-to-use and is ideal for
maintenance crews performing numerous tests. It exceeds mechanical and safety
specifications for shock, vibration and drop tests called out in IEC standards.
It is designed to reject high levels of interference, so it can be used under
difficult conditions such as high stray currents that normally affect accuracy.
The Model 4630 is powered by 9.6V, 3.5 Ah NiMH rechargeable batteries. A
built-in recharge circuit, powered from 120/230V 50/60Hz line, also provides for
testing while recharging.
Applications
-
Three-Point measurements of resistance to ground of ground rods and
grids. Three-Point measurements are generally used when the electrode or
grid can be easily disconnected, if corrosion is suspected, or in
circumstances where ground faults are unlikely to occur
-
Four-Point tests or soil resistivity measurements. Locating areas of
lowest soil resistivity is essential for achieving an economical grounding
installation
-
Touch potential measurements, an alternative to 3-Point tests in
evaluating electrical safety. This test is recommended when the ground
cannot be disconnected, where ground faults are highly likely to occur, or
when the "footprint" of grounded equipment is comparable to the size of the
ground to be tested.
