content: For all it's faults though, the range switch feels good. I suspect there are just fewer traces because a lot of the switching is done electronically rather than mechanically.

content: The only reason to open up a Fluke will be just for checking the PCB revision.Thanks Richard, I did save this page for off line use,I do safe-keep allot of technical material in my hard drives.(The current file size is very good)

content: Quote from: Alex on December 18, 2011, 07:07:30 pmThey did indeed. I complained about it on the Element-14 forums and a Fluke representative popped up and immediately went on the defensive. He said it was a function of how the remote system operated, and their consumer research had found out that users wanted it that way. Now, I would like to know what questions they asked, because I can't imagine they asked "Do you mind if your meter eats a set of batteries every few weeks". It was clear from his response that they weren't interested.So far as I can see, the units chat several times a second, and if communication is lost the RF turns on. Running the units once a second and at reduced output wouldn't have been difficult.
