    keyword=Something not quite rigth with the reading of the calo anode current

    Looking at the epics values read at the beginning of run 6308, it looks like the anode current for the calo are not read. For example block 11 is on, but the reading of the anode current is pretty much zero.

    anode current of block 8 (0,8) :0.000 anode current of block 9 (0,9) :0.001 anode current of block 10 (0,10) :0.000 anode current of block 11 (0,11) :-0.001 anode current of block 12 (0,12) :-0.001 anode current of block 13 (0,13) :-0.002 anode current of block 14 (0,14) :-0.001

    Measured HV on block 8 (c,r: 0, 8): -5 Measured HV on block 9 (c,r: 0, 9): -6 Measured HV on block 10 (c,r: 0, 10): -4 Measured HV on block 11 (c,r: 0, 11): -651 Measured HV on block 12 (c,r: 0, 12): -1 Measured HV on block 13 (c,r: 0, 13): -1 Measured HV on block 14 (c,r: 0, 14): -1 Measured HV on block 15 (c,r: 0, 15): -1

    Also worth noting that the measured current form the power supply doesn't seem rigth either.

    Measured HV current on block 8 (c,r: 0, 8): -10 Measured HV current on block 9 (c,r: 0, 9): -9 Measured HV current on block 10 (c,r: 0, 10): -6 Measured HV current on block 11 (c,r: 0, 11): -657 Measured HV current on block 12 (c,r: 0, 12): -2 Measured HV current on block 13 (c,r: 0, 13): -2 Measured HV current on block 14 (c,r: 0, 14): -1
