Fluke PM6666 counter freezing after 3 seconds from turning on.
<< < (3/27) > >>
pizzigri:
Thank you Coromonadalix,

that is the draft I was talking about... I know that Fluke has an updated service manual for its version of the PM6666 (the one that officially supports 160 MHz instead of Philips' 120) that is over 120 pages long, and that is nowhere to be found.
That service manual is in fact branded Fluke....

schematics in the draft are good, however no silk screen, no part placement on the PCB and a pain overall the trace back parts on it....

What Happens When I Switch to Local?
Switching to LOCAL causes the counter to adapt the set- tings indicated on the display, see ‘How to select function’. This means that the counter will never have settings in LO- CAL which are not possible to set via the front panel.
When switching to remote again, the LOCAL-setting will re- main. Bus-functions like SRQ mask, output separator, EOI, etc. will not be altered by switching to LOCAL and back again.
