    keyword=HRS-R VDC and HV supply

    by using an additional NIM HV supply with local control
    we tested both VDCs and concluded by using cosmic data
    that VDCs are in normal conditions.
    We did several tests and concluded that the unit nominally
    used for VDCs with remote control doesn't work.
    We left both VDCs connected to one output of that additional
    HV suppy. It is on local control, but the HV value and
    the current have reading in the VDC HV "R_TOP" window.

    I advocate to install and use 1471N which is presently available.
