Product Highlights

Self-contained, portable, convenient 120 VAC tester provides an easy way for an electric utility to check the resistance in protective grounding sets used by line personnel.

• Simple one-button testing shows the resistance measured in milliohms to be compared with included ASTM data tables to ensure ground set is safe
• Displays the resistance of each specimen in milliohms with ±1percentage accuracy, from 1 micro-ohm to 6.5 ohms
• Troubleshooting mode can help isolate the problems using included pair of test probes if a ground set does not pass initial test
• Three optional adapters are available as separate items to test special-application grounding sets for underground distribution transformers or switchgear
• All components store in the tester's integral carrying case
