Changing the
Acceptance Tolerance
Over and Under tolerance can
be set from the User menu or
the Setup menu (see Service
Manual) but not both. The
choice where the tolerances
appear is made in the Setup
menu. The tolerances will not
appear in the User menu if they
appear in the Setup menu and
vice versa.
If you change the tolerance but
decide you would rather keep
the original value, press the
^
key in step 2 to return to OVER
without accepting the displayed
value.
Target weight and the toler-
ances are saved in nonvolatile
memory. They are not lost
when the unit is powered
down.
In gross mode, the indicator
will always represent negative
weight with a leading minus
sign. If the weight becomes too
large, positive or negative,
overscores or underscores will
be displayed while the condi-
tion persists.
