Performance Verification Tests
These programs are designed to do the Performance Verification Tests
found in Chapter 2, "Verification Tests."
Example:
Closed Channel
Resistance Test
This example performs the Closed-Channel Resistance Test for all
Normally Open and Normally Closed contacts.
/* Closed-channel Resistance Test E1364A */
