NON-CONTROLLABLE FUNCTIONS
Since
control
and
monitor
functions
of
the inter-
face are
implemented
to
obtain remote measure-
ment
capability
, certain
front
panel controls are
not
implemented in the interface due to
their
local operator orientation. A list
of
these oper-
ator oriented
controls are
as
follows:
