Myself and Josh Crafts attempted to recover the first 40 front crystal temperatures again this morning.
We have ruled out the multiplexer and extension cables as the cause of the problems.
This leaves the terminal block and the manufacturer's cable that connects to the extension cable as possible causes of the issue.
Both the terminal block and the cable are located inside the calorimeter, so we would need to open up the front of the calorimeter to diagnose the problem.
We ran out of time today as the hall closed at 1 PM.
The experiment will continue without the first 40 front crystal temps until the next scheduled down time when we can open up the box and see what the problem is.
We have spare cables and terminal blocks if needed.
