ingredient once the motion, tolerance, and
delay time requirements have been met.
Using Tolerance:
The Tolerance feature is a "tolerance window"
for the preset ingredient during batching. For
example, if the tolerance is set to 5 (%) and
the preset is 1000, the "tolerance window" is
±50. So the scale is in the "tolerance window"
when the display is between 50 and -50.
The auto-advance circuitry of the recipe
function activates the "delay time" counter
while the weight is in the "tolerance window".
The alarms sound continuous at this time and
the preset is considered active. This allows the
operator to slightly "under or over shoot" an
ingredient amount and still automatically
advance to the next ingredient. The auto-
advance circuitry resets the "delay time"

counter.
If the tolerance for that ingredient is exceeded,
the message " OVER " is displayed alternately
or [INGR.#] to advance to the next ingredient.
Setting tolerance to " OFF" allows the scale to
always auto-advance after the ingredient
amount has been loaded regardless of
