Atec AEMC-4610 User Manual

Model 4610 shown in

standard soft carrying case

Catalog #2114.94

Digital Ground Resistance Tester Model 4610 performs ground resistance and soil resistivity tests. Direct reading tester measures from 10mΩ to 1999Ω, and is Auto-Ranging, so it automatically seeks out the optimum measurement range. Easy to use — simply connect the leads, Press-to-Measure and read.

The large LCD (nearly

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

The Model 4610 is fuse protected up to >250V

AC against Accidental

connection to live circuits. In the event of a system fault, it can withstand 250V

AC with spikes of 3000VAC or

1000V

The heavy duty ABS case is O-ring sealed against dust and water and the Press-to-Measure button is also sealed. Model 4610 is battery powered for convenient use in remote field applications. Mechanical and safety specifications, such as vibration and drop test, meet or exceed IEC standards, to ensure safe and reliable field use.

The Ground Resistance Tester Model 4610 is a rugged, easy-to-use instrument ideal for maintenance crews performing numerous tests. The Model 4610 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.

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 also for continuity tests

on bonding

• Color-coded terminals

• Double Insulation

• CE Mark

Applications

• Three-point measurements of resis-

tance 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 (the outline of the part of equipment in contact with the earth) is comparable to the size of the ground to be tested.

• Two-point tests for continuity tests

on bonding or on pre-established grounds. This test is commonly performed in urban environments where proper auxiliary electrode placement may be obscured by confined real estate. Measurements are referenced against a good local ground conductor.

Ground Resistance Tester Model 4610 checks the ground rod using the Fall-of-Potential method.
