AEMC 4620

Product Features:

• Ground Integrity Measurement
• Measures soil resistivity (4-Point)
• Uses Fall-of-Potential method to measure ground resistance (2- and 3-Point)
• 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
• Battery powered with eight 1.5V AA batteries
• Constructed with rugged dustproof and rainproof case
• Color-coded terminals aid in easy hookup
• Suitable for continuity tests on bonding

Applications:

• Measure ground rod and grid resistance
• Measure resistance and continuity of grounding loops around transformer pads and buildings
• Measure leakage current flowing to ground or circulating in ground loops
• Conduct quick field checks
• Conduct field surveys and retrieve and analyze readings from stored data
• Measure earth resistance of the single rod or small ground grids often found in remote telecommunication switching stations
• Measure ground electrode resistance on lightning protection equipment
• Measure the earth electrode resistance of equipment in recreational areas, especially public swimming pools
• Test electrode resistance of installed ground rods and grids at new construction sites before utility power is supplied
• Test earth electrode resistance of grounded towers and counterpoises at cellular phone remote installations and power transmission towers
• Three-Point measurement of large grounding grids, counterpoises, ground mats, and grounded equipment
• Locate areas of lowest soil resistivity which is essential for achieving an economical grounding installation
