WebThe continuity test (also called low resistance measurement) is measuring the low resistance of cables, from 1 mΩ to 250 Ω. The continuity test can be made in 2 or 4 wires according to the resistance to be measured: 2 wires for resistances > 1 Ω, and 4 wires for resistances < 1 Ω. The continuity test in 2 wires mode consists in injecting a ... Web• The test is used to identify excess resistancein the grounding system that could limit the effectiveness of the ground to perform its intended level of shock hazard protection. Test Objectives: There are two objectives to keep in mind: 1. Low Resistance: The main objective of the Ground Continuity Test is to verify that the
