  09:20 UT, power-line glitch (lights blinked) and HV off. HV fuse still OK, restarted. Did notice that the fwd and rev power meters no longer show anything. Checked +24V and +5V supplies at rear- OK. Noticed PC clock 4min 19sec slow ! at 09:32:41 UT. Corrected at 09:42 UT.
  Various tests of spare SKY boards in our PC- OK, they work. Spare ADC does not work in our PC.
  After having HV and Fils off during ADC/SKY tests, I tried to switch them on again. Got Iav 200-300 mA and relay clicking. HV fuse still OK (0.7 Ohm). Switched off and run on A300 only while I leave for Svalbard. (MTR).
