Point-to-Point Continuity Test Procedure

Point-to-Point Continuity Test Procedure

• Power off the cathodic protection unit;
• Connect test leads to voltmeter on 2 volt (or lower) DC range;
• Place test leads to individual structures
• Test and record voltages observed

Make the judgement based on the following criteria

V≤ 1 mV, the structures are electrically continuous.
V≥ 10 mV, the structures are electrically isolated.
10> V>1 mV, it is inconclusive and further diagnostic testing is required.
