Last night at 1/5/2019 at 22:39 there was a 5 second period where the signal went from 4.5K to 255K. 

All signals that go into this this signal jumped at this time. 
CCM_DT_MAX 
CCM_USHR_DT
CCM_DSHR_DT

But only the first one above went to 255K.

A similar alarm went off this morning at1/6/2019 at 6:16
This time it was triggered by a quick step change from 4.5 to 43K on  the USHR signal.

(Neither of these can be real temperature changes so it must be something in the instrumentation)
These were false alarms. Can we find a reason and stop it from happening?

Thanks
Dave
