These programs are designed to do the Performance Verification Tests
found in Chapter 2 - Verification Tests.
Test 2-1: Closed
Channel Resistance
The purpose of this test is to verify that all channel relay contacts meet the
closed channel resistance specification for the multiplexer. If the closed
channel resistance of any contact is greater than 3.5Ω, the relay should be
replaced. See Chapter 2 for hardware connections and equipment setup.
