    HV issue with 1458,
    the HV channels on 1458 still trip at 1200 V.
    We tried with one operating one on the other crate, it trips the same. Using another power supply we reaced 1500 V without any problem on channel 270.
    We plugged channel 253 on channel 255 of the 1440 crate since it was not used.
    I will try to look for another HV power supply to try.
