Just a safety suggestion - If you have a HV probe that has been dropped, or
has a crack in it of any kind, DO NOT use the probe until you can test it,
and verify that it is safe. I watched someone get hit really bad after using
a probe that they dropped on a conrete floor. He went to move the probe to
the side a bit so he could adjust the HV in a monitor. Unfortunately, this
was an older guy, not a real strong heart. He nearly killed himself. I'd make
sure any probe that has been dropped is not leaking before you touch it with
the juice on...
