[Dsg-rich] broken Humidity sensor on left side of RICH to be swapped with spare interlock cable

[Tyler Lemon]

Hello, 

This afternoon, Mindy replaced the humidity sensor on the left side of the RICH that was not working. After connecting to the feedthrough, we were still unable to read the humidity for that sensor. This most likely means there is an issue with the PCB board. 

To avoid a delay in planar mirror installation while the board is fixed, I gave Sandro and Marco the spare nitrogen volume interlock cable from Mindy's desk and verified that the temperature sensor and humidity sensor are working on that board. 

This evening, they will remove the cable with the broken humidity sensor and install the spare in its place. We will then be able to repair the cable with the broken sensor for use as the spare. 

Best regards, 
Tyler
