@Shalini-Subramanian, after addressing these latest comments, I think this is ready for a final tech writer review. Once the tech writer completes their final review, I'll do one final pass myself. Thanks!
| 1. **Add the measurement instrument** (for example, a DMM or a DC Power instrument). | ||
| 2. **Add a multiplexer instrument**. | ||
| 3. **Set the Multiplexer Type field** to match the type identifier that your code uses when your code calls `GetSwitchNames` and `SetSwitchSession`. | ||
| 4. **Define the DUT pins** used in the multiplexed connections. |

| 1. (Optional) **Initialize the Relay Driver Module session** with the existing STL `SetupAndCleanupSteps.SetupNIRelayDriverModuleSessions` method. This method is typically in ProcessSetup. |

@Shalini-Subramanian, please change "... that test program was created..." to "... the test program was created...", otherwise looks good!
