Resetting The Storage Memory
If
there
are
problems
with
the
functioning
of
the
menus
,
which
may
occur
due
to
excessive noise
when
the
roughness
tester
is
powered
from
the
mains
,
the
storage
memory
must
be
reset in
order
to
restore
proper
working
conditions
.
However
,
note
that
the
resetting
involves
the
elimination
of
all
the
presettings
and
flags that
enable
the
software
to
restore
the
condition
prior
to
the
switch
-
off
.
The
reset
is
performed
by
holding
down
the
key
while switching the
instrument on
,
and releasing it only after the mention appears
on the display.
It has been done correctly if, when you press the key again, the
following signal is displayed and if, when you check in the
menus, all the functions (print parameters, tolerances, etc.) are
disabled, and the cut-off is equal to 0.8.
If this is not the case, leave it to switch off and repeat the operation.
