GP-2A Ground Resistance & Resistivity Tester
DUAL RATED
For installation and troubleshooting, this instrument provides accurate and reliable
measurements of ground resistance and soil resistivity to help you reduce power quality
problems.
• Measures earth ground resistance with
3-point (fall of potential) or 2-point tests
• Calculates resistivity with 4-point test
• Automatic voltage measurement prevents
false measurements

DGC-1000A Clamp-on Ground Resistance Tester
User-friendly and accurate, the DGC-1000A helps you work safely without test leads or auxiliary
electrodes. The on-board memory and data logging features improve efficiency.
• Accurate ground resistance measurements from
0.025 to 1500 Ohms
• True-RMS current and leakage current
measurements
• Accurate readings in less than 10 seconds
• Audible alert if continuity beep if the resistance
is below 40 Ohms

TOP R ATED
“Great instrument. An advantage to have.”
“On a motor grounding job where 800hp motors were failing on a continuous basis, we were able to pinpoint
the lack of proper grounding that was causing harmonics and energizing armature shaft, to the point where it
was reading 400v. On that job alone this tool proved invaluable and allowed the customer to save thousands on
downtime and predictive maintenance. This tool will become a gem in your tool-bag just clamp it on and take
live readings without breaking connections, I highly recommend it”
