AEMC 3620 Ground Resistance Tester Kit - 500ft

The Analog Ground Resistance Tester Model 3620 performs ground resistance measurement from 0.5 to 1000Ohms with speed and accuracy. The Model 3620 features three-terminal operation for fall-of-potential earth/ground resistance, and may also be used for 2-Point tests.

The large 3.1" logarithmic scale is easy to read, with a separate marking for 25Ohms. A large Press-to-Measure button allows for easy measurements. A manual zero adjust is provided for accurate readings. Color-coded terminals are easy-to-use banana plug inputs and binding posts.

Applications

The Ground Resistance Tester Model 3620 is the ideal instrument for electrical contractors, power utilities, REAs, telephone and CATV technicians, and inspectors who must check ground to determine compliance with NEC, OSHA and other specifications. Applications include:

• Measuring earth resistance of the type of single rod or small ground grids often found in remote telecommunication switching sites
• Measuring ground electrode resistance of lightning protection equipment
• Measuring the earth electrode resistance of equipment in recreational areas
• Testing electrode resistance of ground rods and grids at new construction sites, when utility supplied power has not been supplied
• Testing earth electrode resistance of grounded towers at cellular phone remote installations
