4630

4630 is a digital ground resistance tester that performs ground resistance and soil resistivity tests. This direct reading tester measures from 0 to 2000Ω, 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 specified 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.

• Ground integrity measurement
• 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
• Extremely simple to operate: connect/press/hold/read
• LED on faceplate informs operator of high i/p noise, high auxiliary rod resistance, fault connection
• Large easy-to-read backlit display
• Rugged dustproof and watertight field case
• Low battery indication on LCD
