We (read that I,) did a similar thing to a Fluke 4-1/2 digit dmm. It
was reading the reservoir voltage on a high voltage thyratron when we
cranked up the main HV. Only got RF to the fluke but it went south
for the winter. Again cost about $30 to repair.
Al did the same thing to his Data Precision. We fixed it in house, for
a new fuse.
That same fluke is subject to LDC screen failure after moderate drops,
(waist high to floor.) Twice already in about 6 years.
In summary, although we have only one fluke to go by, our Fluke has
not really demonstrated ability to take lots of abuse. Other than its
tendancy to go south for the winter under minor abuse, (and take a
loooong time to get fixed,) it is a very nice unit.
