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.
