AEMC 3620 Ground Resistance Tester

AEMC 3620 Ground Resistance Tester

The Model 3620 features three-terminal operation for Fall-of-Potential earth/ ground resistance and also may be used for 2-Point tests.  The large 3.1" logarithmic analog scale is easy to read, with a separate marking for 25 Ohms

A large Press-to-Measure button allows for easy measurements.  A manual zero adjust is provided for accurate readings. Color-coded binding post terminals are easy-to-use with banana plug and spade lug inputs.  The heavy duty ABS case is O-ring sealed against dust and water, and the Press-to-Measure button is also sealed.  The Ground Tester Model 3620 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 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.
