    Investigated the T5- module 2 problem.
    
    - With all anodes off  (as found this morning)
        Field a1 1350 see 260 V on cathode hv channel (no current).
    
    - Field at 0
        at small cathode voltage (400V) see 49 micro A --> 8 MOhm short
        No apperant cross talk to anode wires. *xu, y, or v)
    
    - Set all demand & deafult voltages for T5-2 to zero
    
    - Should operate remaining modules T5-A1 and T5-A3 with default
    voltages.
