keyword=VDC thresholds
Noticed at about 10:30 after lowering prescales that the DAQ deadtime went through the roof. The cause was right side VDC thresholds = zero. This was almost certainly the result of the VDC high voltage going to zero during an earlier crate reset. We failed to notice that the thresholds had gone to zero as well. This should probably be alarmed in some fashion or at least have the threshold readback on the control screen turn red when the thresholds are out of spec.
