7.Measure the resistance across the contacts. A resistance of less than one ohm indicates that the con- tacts are closed. An infinite resis- tance indicates that the contacts are open. Energize the 24VDC power supply and measure the resistance again. Compare to the conditions given in Table F.2. If the readings do not match the table, the relay is faulty and should be replaced.

8.Repeat the above procedure for all of the contacts.

9.Re-install relay into the relay board.
