    keyword=CH scaler problem

    Looks like the CH scaler data is bad for run 12382.  (Gee, I thought
    it was ok last night.  Problem seems to be intermittent.) 
    
    The symptoms:
    
    1. All channels have a frozen value -- does not fluctuate even 
    by +/- 1 which is very suspicious.
    
    2. Every few K events (e.g. 5191) all values jump to a very 
    large number simultaneously on all channels.
    
    We can swap out this scaler and see if it helps.  Next opportunity
    or when I'm told to.  Meanwhile I'll recheck signals.
