Sue Witherspoon (from ACC) did modify the Calorimeter DC monitor GUI. The match between the epics values and the block number is now correct.
Note: this morning we did test the ADC reading by plugging a battery in place of each PMT signal. We noticed that it took ~30 s for the epics readings to come back to its base value once the battery got unplugged. So one should keep in mind this fact when measuring rapidly varying conditions.
