    Fluke 199C

    Hi, I'm facing a problem with my FLUKE 199C oscilloscope battery which becomes dead very often and the oscilloscope will not turn on anymore even when the power adapter is connected. Is there any way to make it run on the power adapter regardless of the battery condition.

    is PV worth it - 9 panels facing west

    I'm starting to think a PV system just isn't worth investing in for my roof, considering only 9 panels and the roof faces just 18 degrees south of due west. Another factor seems to be how much of the electricity generated could be used, rather than sold. I'm thinking of it all ways round, but I...
